I’ve got a description here! This topic is so deep, I don’t even know where to start. We’re gonna talk about fish today! Welcome to the beautiful world of aquascaping! Sorry Balazs, but not today! Why not? Welcome to the beautiful world of fish! Oh yeah! This is a big topic and we have another video on that actually on this channel, with Jurijs and Gyula Pasaréti, a famous Hungarian fishkeeper. Check that out, we’re gonna link that in the description. We have all the names of all the fish in the descriptions under each video. We will try to answer all the comments below this video. If you have any question about fish, – it’s not we, it’s gonna be Lory actually, because he knows everything about fish. So if you have any questions, please do not hesitate to ask them in the comments below this video. [Background] The fish have arrived! Oh yeah, let’s go, get the fish! 500 fish! Alright, so we have two boxes of fish actually. I’m gonna make room for them and we’re gonna place the box on the table. Oh, you already put it! [Lóri] Yeah! We do receive some comments from time to time, accusing us maybe, or just asking us, whether we take the need of the fish into consideration, when we’re building, or maintaining a planted tank. And I want to talk about that just a little bit. Aquascaping is about the harmony of the hardscape, plants and fish. All of these are equally important. So we will try to create an ecosystem, which is suitable for fishkeeping, it’s suitable for having healthy fish on the long run. What kind of fish do you want to choose for your planted tank? I want to talk about four aspects here. The first aspect is the color. So what is the best color for fish in an aquascape? What would you say? I think it depends on the hardscape and also depends on the plants. [Balazs] Yes! Do you want the fisht to contrast the layout? The hardscape, as Lóri said. Do you want the fish to blend in? The second aspect, however, is the size. So what size of fish is suitable for a planted tank? I’m always saying that I don’t want to choose big fish in a layout, because then the layout itself would appear smaller. The third is the fish habits. So behavior is really important. Do you want fast movement, shoaling fish in your tank? Or you just want fish, that are a little bit more static, to accentuate the calmness of the layout. Do you want fish, that swim in the upper area if your tank, or you want to have fish, that swim in the lower area. Or you want some bottom dwellers, like Corydoras – the little dwarf catfish. [Lóri] And they are also useful, not just moving on the bottom. And the fourth aspect would be the shape of the fish. If you’re doing a contest tank and if you’d like to accentuate the dynamics of the layout, you can choose fish that are longer – they look more dynamic. And if you want to accentuate the calmness of the layout, you can choose fish, that are kind of roundish, so they would look better in a very calm layout. How many fish can you use in a tank? That was another question. There’s somebody coming! Do we need to open that? Some more fish are coming? What’s happening? [Lóri] I don’t think so. So how many fish can you use in a planted tank? Well, you can use as many as you want and as many, as your filter can cope with. It’s already done? Yeah! You have everything! Alright, so how many fish can we use? We’re discussing about the number of fish in a tank and I’m always saying that filtration is the most important thing. [Lóri] Guys, it’s really important, when you buy these fish, you know, it’s not the final size. So try to calculate with the fish later growing bigger and producing more waste. You can only introduce the fish, when the filter is cycled. So when you set up a new tank, you really have to wait at least three weeks, or more, until your filter cycles. If you have used the startup bacteria for the filter, obviously the filter will cycle quicker. We say, that the second week you can put in the algae eaters, and when all the algae is gone, later you should try to put in the other fish. The community fish for example, or any other fish that you want. But if you can wait a longer time, it’s better. The longer, the better. And actually algae eaters are very important and I’m glad that you mentioned them, because you really need to cope with the algae, that comes at the beginning of the lifecycle of the tank. Okay, so let’s talk about the algae eating crew! We have a number of fish, that we prefer here, at Green Aqua. For me, probably the best algae eaters are the Amano shrimp and the Siamese algae eater. Another very good fish is the Otocinclus Affinis, which can eat the brown algae. And the other one, that I really like is the Clithon corona snail, which can eat… [Lóri] The dust. And the black brush algae. – Also the black brush.
– And the green dust algae. Yeah and the green spot algae also. What are you doing now? [Lóri] I’m just helping Ati! Oh, you can like tear that? Yeah! What are you doing, you tear it? Yeah, because it’s a very tiny pack and… Oh so then you do a knot in the beginning, and then you bend it over, right? It is a double bag! So it’s a double bag, right? Cool! How do you transport the fish? So when you buy a fish at Green Aqua, what do you do with them? We usually pack small fish together. So it’s not good, if you put together small fish and big fish. If you travel far, we can put some Oxygen in the bag, that’s okay for one day. In this cold weather we need to keep them warm too. How do we introduce the fish in the tank? This is a big topic and you guys are gonna see, when we unpack these, we’re doing basically the same thing. First of all, the temperature needs to be the same. And for that reason, you need to put the bag inside the tank and just let the temperature equalize. And also, you need the water parameters to equalize, which means that you need to punch little holes. It is better for the two waters to mix and you shouldn’t be afraid of bringing in any diseases together with the water. [Lóri] If you’ve got any problem with the fish, it doesn’t matter, if you put this water in your aquariums, or not. There’re no parasites in the water, that are not on the fish. Without the fish, yeah! Alright, the colors of the fish. So you have to know, that when fish are stressed, – and obviously a transportation will always bring stress to the fish – they’re gonna look a little bit worse. More worse! A lot more worse! If you have the same pale colors after a couple of months, you have to be sure that you’re doing something wrong. Which means that you’re not feeding the fish with proper food, or they have some problems with Oxygenation, or something stresses them. We use Dennerle food, the Color Booster, Hikari’s Micro Pellets. And Hikari’s Micro Pellets, and we use a third Dennerle product. Yeah, there’s Dennerle Gourmet Menu. Maybe twice a week, I also use frozen food. It’s also important guys, don’t forget it! What about live food? Would you recommend that? I think the frozen food is better, because of the parasites… Also, it’s better to keep. Cause I remember those worms in my toilet… Yeah! …in my childhood, I don’t know. That’s why I don’t like… My mom stepped in: “Ayy, what’s that?” What about the bottom feeders? We also have two types of food from Hikari. One for algae eaters and one for other types, for example catfish. Alright, so algae eaters need plant-based nutrition, so they obviously have a different composition. I feed our fish every day, excluding the weekend. [Balazs] It’s good to starve a little bit sometimes. Yeah, the weekend is for the diet. Diet time! Yeah, okay! Please be confident guys, to feed your fish daily at the beginning. After like six months, you can stop feeding them daily and feed them every other day. [Lóri] But it also depends on the kind of the fish. There are some fish that need daily feeding, like the bigger fish, or something. Yeah, for example. How much do you give them? My rule of thumb is that I give them enough food, so that they can eat it in about 2-5 minutes. Usually I start with disconnecting the filter. That’s important, because I think it’s easier to feed your fish. I think you don’t want to run, while you eat your lunch for example. Sure! I start by feeding small portions, that they can eat in about a few seconds, not more. So you just feed them. [Lóri] Yeah, I wait a few seconds and I repeat it. Everything that we’re talking about here, is a rule of thumb. Okay? So this is like a general idea and don’t blame us, if your fish die. What do you do, when you have algae eaters, and you have no algae. Sometimes I can see they can eat the normal granules also, but the sinking tablets for example are also good. For the algae eaters, it’s important that it’s plant-based. So what would you say, how long can we comfortably go away from our fish and starve them to death? So if your fish are in a good shape, it’s possible not to feed fish for one week. What about my grandma, because usually people ask their grandmother. You told them not to overfeed them, but they usually do. You can put some portions to… Oh, like do it in advance for them! Yeah, yeah! Not more, yeah! In those portions would you pack more, or would you pack the same amount, like you usually feed them. Maybe I think less is better. Maybe grandma can’t turn off the filter for example, and the filter will suck it in… Grandma can’t turn on… I was just… I was picturing it, like what would grandma do? Let’s talk about the lifespan of the different fish. [Lóri] Usually the small kind of community fish for example live between 3-5 years, the smaller shrimp about 2-3 years… [Balazs] Okay! The snails? About the same time. Alright, so what would be the longest living tropical fish, that we have here and we sell here at Green Aqua, what type of fish? [Lóri] For example the Corydoras. [Balazs] Oh yeah, they could live probably 16 years! [Lóri] About that, I’ve heard of it. Okay, so what about the fish, that jump? We don’t really like these types of fish. Can you name one? Dermogenys pusilla. Okay, it’s a beautiful little fish, and I really like it, but I don’t really want to use it in a planted tank. If the water quality is good, if they feel good, they will not jump out of the tank. And obviously you don’t want to fill up the tank to the top. Let’s talk about the Amano shrimp trying to escape. I heard a very interesting story about that. They’ve been living in ponds in the nature. When the ponds dry out, they tend to migrate to another pond. What you see is that they’re trying to go to another tank, because they’re probably getting bored, or whatever. What we say here at Green Aqua, is that they just want to go back to Japan. It’s important, that you need to keep good water parameters. Yeah! If the water is cool, then it’s… And the other thing, what I think it’s important, is feeding them. Because if they don’t have any food, then they’re gonna try to find a more favorable tank. People were asking me to do a Cychlid tank. Well we’re not gonna do a Cychlid tank, because we cannot put plants in it, so it’s not possible, to do it. I’m trying to find only one type, a main type of fish in a tank, because I really like the minimalist style. So I want to have one type. But if you want to have two or three types, this is a good thing. You’ve got some fish, that would compensate each other quite well. So for example in Tommy’s tank, – a 120P beautiful Iwagumi -, you have the Ember tetra together with the Rasbora Kubotai. And one of them is red and the other one is a green fish. These two go together quite well. Or for example, if you have got one kind of community fish, that are not brave, you can mix them with another kind of community fish. So they would come out from their hiding place? Alright, so “these guys know what they’re doing!” “It must be safe, so let’s go out!” If you build an Iwagumi, that has no hiding places, what happens then? Would they be stressed? [Lóri] No, because I think the community fish, they don’t need hiding places. [Balazs] Who needs a hiding place? For example the catfish. The catfish will probably need, they will probably disappear. Yeah! Let’s talk about the temperature, because that’s another question, that I always get. Tap water is really cold during the winter, so if we don’t wait for that, to go back to room temperature, you can stress any types of fish. [Lóri] Yeah! We don’t change the water with GH 0… For a GH 3 tank, as then fish are gonna be super stressed and they’re just gonna die, because of the temperature change and because of the water parameter change. Obviously, when you’re changing 50% of the water weekly, you’re not gonna have problems with that, because the GH will not fall down to zero. Okay, so let’s talk about the fish health in a planted tank! Some of you guys have told us, that you have problems with fish in your tanks. Here at Green Aqua, for some reason, we don’t have so many sick fish. Also it’s because of the TwinStar, I think. It helps a lot! TwinStar is sold and advertised, as a water sterilizer, so I’m really happy, that we don’t have that problem here, at Green Aqua. We do have some fish arriving here that look sick and Lóri is good enough, to identify all these problems and the biggest thing that you can do, is to know, what kind of disease you have. Whether it’s a fungus, or it’s a bacterial infection, or it’s the “Dara-kór” – I don’t know the English name, we’re gonna put that here… Probably it’s white spot… White spot disease? Alright, so the white spot disease. I think that we have promised you, to do the unboxing video for this. But the light died and it’s already too late, and it’s already we’re there 15 minutes into this video. So I think that we’re gonna continue this video the next week, so you’re gonna see the unboxing. And I promise you, these fish will not stay here for a week. Hit that like button, if you like what we did here with Lóri! Thanks again for your help! You’re welcome! We’ll see you next week! Bye! Bye! What I forgot to tell you, is that we’re gonna come back in two weeks with this unboxing video, not in one week, because next week, you’re gonna see the ADA workshop. I’m really excited for Daichi Araki and the ADA, having a good workshop here. So stay with us for that!


  • I keep seeing German Blue Rams in video's like this promoted as good aquascape fish. How do you reconcile the high water temp requirements of German Blue Rams with the low water temps needed by many aquascaping plants?

  • My hygrophila siamensis 53B keeps melting away (holes on leaves , chunks of the plants float away) no matter what I do. I plant it in fluval flex 15 gallon, stock equipments and daily dosing with nilocG fertilizer. No CO2. All other plants (rotala rotofondulia, crypts and mosses) are doing well and I can't figure out why this supposedly 'easy' plant is such a struggle for me. I've even purchased new and different strain of hygrophilas and it just keep doing the same thing over the few months 🙁

  • Great video! Just wanted to point out that the 2-5 minutes rule of thumb for feeding is not always the best to go by simply because it increases the chance of over feeding your fish. I’d say do research ladies and gentlemen depending on the fish you get to really feed your fish the right amount. For my betta fish I feed only 4 small pellets some days and 3 bloodworms other days and 3 tiny little pieces of frozen mysis shrimp other days to mix his diet while still keeping the amount appropriate for my betta. Also there’s research for how many fishes to have in a tank according to the type of fish. Is never how many fishes you would like because that can cause overcrowding in your tank. Just some tips I’ve learned over the year of research to make sure we provide the best environment and diet possible for our aquatic friends!

  • I'm curious about your thoughts on German blue Rams and their higher temperature requirements in the planted tank. I know you guys run your temperature lower but do you have success keeping higher temperature fish in a planted tank? Thanks!

  • Best thing i ever did with going away for both reef and fresh tanks was lay out the daily feed amount in icecube trays and freeze in ro water. That way the person looking after your tank knows to just put 1 ivecube in each day..done and no excessive feeding disaster!👌🐠

  • Man such an informational video as always. I was pumped for this one ever since you replied to my comment about acclimation. Your explanation totally makes sense too so I'll be using that introduction method from now on. Thanks for the tips Lori and Balazs

  • Dude, WTF! The issue with the grand-mothers-feeding-freenzy it's fucking real and international… I though it was just me… D:

  • Hi, will you recomend to feed fishes in planted tak by Artemia salina?

    I wonder if this kind of feeding will increase hardnes of water. Thanks

  • Great video!
    So easy to forget about the needs and importance of the fish in planted tanks. I had a great chat with Tomi and Viki yesterday about what fish works best for a contest scape. I'd love to see a video from that angle of the fish part as well.

    Thanks for all the knowledge Lóri 🙌🙌🙌

  • Nice as always. // I stop use Crossocheilus because eats my Java moss and other similar mosses, even having special food for herviborous fish mixed with other foods … Saludos!

  • You guys are so hugely informative! I love love love this channel!

    I only have a 60L tank, and not much money to do any crazy cool hard scaping like what you do, but you guys inspired me to really think about how to maximize the impact of what I could afford and I think for my first go on a really small budget I did pretty good 😊 and I had so much fun watching through your videos to pick up little ideas and tips here and there 😊

    I'd love to see you do a tank with a big school of rummy-nose tetras (one of the types of fish I got) I think the schooling looks so good, especially in tanks that are long rather than tall 😊 keep up the amazing work you guys! Love from Ireland 🇮🇪

  • Finally a fish video 😁 It would be nice to see more of this. Like for example at the end of the scaping video you could about the fish you're going to stock it with and give us some info on their max size and water requirements

  • I wish we had more options for bright white fish. I have some platinum white guppies in a dark naturescape and they look amazing.

  • Love the channel and videos. Would like to visit your country some time.

    I am converting my Red Sea Reefer 250 from saltwater to freshwater planted because of you guys. Keep up the good work.

    Chris from NJ

  • Thanks for videos like these. I'm thinking about jumping into the hobby and it is really helpful to hear open, honest advice.

    One question: I'm thinking about starting with a blackwater betta tank. What would some of your favourite tank mates be if I wanted a bottom dweller and a school of fish to hang out with my betta too?

  • 1 cm fish per 1 litter is not correct way of measuring how many fish can be kept in a tank by any means, biased on that analogy a 30 cm Koi can be kept in 30 litter tank!

  • It's good to know that no matter where in the world you are, there is always a grandmother that wants to over feed you…or your fish. LOL! Thank you for another informative and excellently produced video!

  • Hello guys, I have 52 Gallon with:
    2angels, 3 corys, 5Ember tetra,2 silver foxes.
    Can I add more fish in there ? (Smaller or bigger whatever)!!
    And yes I have lightly planted tank! With black background!

  • Hi I’m new to the hobby & am starting slowly. Is it okay to put a couple of adult shrimp in a small planted tank with one male betta or could you recommend anything to keep him company. I love your videos & am learning so much. Thanks Tony in UK.

  • Great video! Lots of info and tips! You guys always put out awesome videos! Plus the aquascapes and fish look amazing! THANK YOU!

  • First of all, I would like to point out that the content of this video does not have a trace of a rule of thumb. I. e. 1cm per Liter is not valid in the case of a planted tank since it disregards the open swimming area, which is vital for any species. For instance, You did not mention that Crossocheilus reticulatus tank should be at least 100 cm in length as this fish needs an awful lot of space. In addition, it likes to graze on mosses, especially Fissidens mosses. If you are not careful, you will have no Fissi in your tank in no time. Fish jumping out of the tank has to do with a) quality of water b) the imbalance of sexes (males per female ratio), c) light suddenly switched on (there is a reason why LED light manufacturers placed more emphasis on dimmable lights).
    And now my marketing past comes out. As Lóri knows well, there should be a separate vlog on which foodstuff is suitable for which fish species (mouth stand, behavior in nature, hence which of your products are suitable as a staple diet for a particular fish). With that kind of vlog, you can hit two flies with one stone.

  • man! soooo much to know before hand. I bought my first tank a month ago and just wanted fish in it… until I found these videos and started to learn about aquascaping lol damn it 😛

  • what name instagram balazs farkas?

    Fyi : my latest aquascape settings are finished, I want your criticism and suggestions from you, may I send the photo via ig 😁

  • Can you do a.short video on plant pearling and also can you answer if all pla rs pearl or there are only few plants which pearl

  • Hey guys! You are all awesome!
    How about a challenge, ppl always commenting on your videos stuff like "I can't afford this" or "I would love a beautiful Aquascape tank if I had the money", how about Balázs, Viktor and Tommy each get 150 Euro as a budget and see what they can each achieve.
    All tricks aloud, buy used hardware, find hardscape in nature for free, or even find ppl on Facebook that wanna give you some clippings.
    No making special offers in own shop, no harvesting from own tanks and documenting where you got it. No going over budget.
    Let's see who is more resourceful and creative.
    Love your channel, thank you!

  • Hello guys thanks for the great videos! Can you do one on the plant for hire temperature fish tank, like a discus tank? Thank you.

  • I heard you mention that your filter depends on how many fish you can keep. I was wondering your thoughts on using a sump. Do they work as well as a canister filter?

  • Hi GreenAqua.. would you make video how to add details touch with different tank? adding detail in different iwagumi tank, jungle and etc. I need inspiration.. i just build tank, but when adding details i stop for makesure something. I allready saw it in few videos but i think better to make it in one video so noob like me can easily understand 😅

  • I try to make yt Chanel talk to move a nature near to your room house.still want fix some Besic problem .Camera and all media stuff and some little think.There is so much thing on my brain i want to make it to be realita.pipe garden,vertikal garden,wall water garden,And Manny idea. And this Aquascape it one of it,but it will take a time. I start with empty bottle Chivas

  • Hi, can you recommend some open-aqua-friendly (not escaping 🙂 snails? You mentioned clithon corona – how about clithon sp., neritina, …?

  • Hi, do you have experience with green neon + neocaridina shrimp? Will the fish eat shrimp babies or it is safe combination? Thanks a lot…

  • @Balazs in one of the videos you mentioned a quote from Amano san that goes something like "a tank without fish does not have a soul" or something like that…..can you please mention that exact quote here or point me to that vdo at least?

  • Great video and I real like that you told us all the name of the fish that you showed in the video, I have only one question: There are any cichlids that can live in a planted aquarium?

  • I have a planted tank with 14 types of plants. My tank size is 45'30'36 cm.3 weeks ago my all fish died strangely. Before that day all fishes were good the color was good Guppies had some babies but that day all fish died first the big ones then the babies. Then I changed 70% water, the next day 30%,the nextday 20%.I changed10% water daily. After 3 weeks I have bougt 6 new fish but they also feeling stressed. Another thing I don’t have check valve in my DIY co2 but I don’t think in day it Can't kill all my fish in one day that it couldn’t do in 4months.So what should I do?

  • My question is , do neon tetra and amano shrimp will be fine in little bit of high water flow ?

    Due to algae issues i added small pump for better water circulation in my 12 gallon planted tank ! After a week algae is gone and it's been 4 weeks so i want to add neon tetras ! Please guide me ! 🙂

  • Looking forward to the unboxing. With regards to the jumping fish… I find that psuedomugil luminatus and clown kilifish like to jump out a lot. This is especially when lights are out and you are walking around in front of the tank. This is inspite of having the ADA glass cover. Do you ever notice any fish that have jumped out in your gallery??

  • Hi, I set up a pretty nice planted aquarium with lots of small shrimp. I was wondering what mid or top level swimmer fish would be suitable to keep with these shrimp, other than harlequin rasboras and tetras.
