Foo the Flowerhorn : *Most ASKED questions:* *Did you put the fish and shrimp in or did they come from plants?* A: I put 4 wild shrimps, 2 Amano shrimps, and a nerite snail first. You can see their first day in the “2 months update” video : https://www.youtube.com/watch?v=BBGcPGQvO9Y I put the adult sparkling gouramis in the “3months update” video: https://www.youtube.com/watch?v=xut0YAvE8eQ The baby fish that are in now are the second generation. They first appear in the “4 months update” video: https://www.youtube.com/watch?v=FtdkRe6VjSs The wild snails and infusoria came from the plants. *Does this tank smell bad?* No. b/c it’s an established tank and the plants are all doing well, it doesn’t smell at all. My friends who aren’t into fish agree. However, in the beginning, before all of the plants were established, it did have a very faint fresh soil smell that you can only smell if you put your nose right next to it. *What’s the music?* A: It’s in the description. At the bottom. *How did you make this tank?* A: The “setting up” video: https://www.youtube.com/watch?v=ZvmGJuquuLE *How did you make the plant separator?* A: I made it. You can see it in the “2months update” video. *Why is water so clean and how do you clean this tank?* B/c I’m using the plants as filter, they are doing most of the work. The glass hardly gets dirty. It does get dirty maybe once a month or every month and a half. Then I use a magnetic algae scrubber. I showed this in the “setting up” video, and the link is in the description. Things I do to maintain this tank is: I feed it once a day. I do around 5~10% water changes once in a while to get rid of surface bio-film. And usually 25% water change once a week or once every 10 days. And trim the plants when they get too bushy. I never vacuum the substrate. *This is #6 video of the series of this tank. All of the video links are in the description. Also, all of videos on planted tanks are in the description, too.*

TerminalMontage [Jeremey] : This is the cleanest looking dirty tank I've ever seen.

Zena : I have no idea what’s going on but it’s really cool!

OtakuBKツ : I don't know what's happening but I like it

dazhibernian : Instigate a world war between them, keep the population under control.

Maria Atwani : Me : have tons of things to do Also me : watching every minute of this video

Bret Maverick : WHY IS THIS IN MY RECOMMENDED HAHAHA Low-key enjoyed this immensely though...

therandomdot : For folks needing some explanation ... when left alone, every environment reaches a point of homeostasis.. a point where the energy cycle balances itself out. Food chains work in trophic levels, with plants being base level producers of food by taking in light and growing. Then next level animals (consumers) eat them, then next level animals eat them, etc, etc... then they produce excrement and die, and that floats around as detritus to either feed decomposers (like bacteria) or other consumers (snails). When an environment is left alone, the populations of all species in the environment will explode and retract until they reach a point of homeostatic balance.. . EG: at first, there will be an explosion of plants that establishes the ecosystem.. then there will be an explosion of first level consumers as there's an abundance of plants to eat.. but they will over-eat the plants. This causes a temporary population explosion, but in the next wave of life cycle, since so many plants get eaten away, the consumer population starves itself back down to a manageable population that the first level producers can support. (This happens in the wild all the time, and in biology they usually use deer and wolves as the example. During a good growing season, deer will propogate like crazy, which means wolves can propogate like crazy from eating a bunch of deer. Then if the next season has a drought, there won't be enough food to support a large deer population, so the large wolf population will get culled via starvation back to something that can exist with the lower deer population.) "So, why is he feeding them flakes?" Well, it's estimated that the jump to each trophic level requires consuming 100x a creatures weight in energy in order to survive. So, first level consumers will need to eat 100x the amount of plants to survive, second level consumers will need to consume 100x the first level baby shrimp to survive, etc. But, only 10% of this consumption is used for growth. The rest is expended as energy... to move, to heat, etc. Energy is lost to the environment ... and while this can be considered a "closed loop" environment .. if you think about it it still has interaction with the outside environment. The heat the fish give off via movement or body temperature is transferred to the water.. which can get transferred to the glass of the aquarium, which is then transferred to the air in the room. That is a loss of energy from the environment. The movement of something near the surface disturbs the water, which disturbs the air molecules above the water.. the energy is transferred outside of the environment. So, while it's a fairly efficient "closed loop" environment, there are still losses of energy to an external environment (his room). In order to maintain a steady population, you need to supply extra energy to "top off". If he really wanted to just keep it "closed loop", he'd only use the lights to supply new energy .. because the level 1 producers (plants) take it in as energy and convert it to food that consumers can eat and keep the food chain going. But, by supplementing extra food, he can ramp up population growth beyond what only the plants can maintain.. essentially, adding food to the tank is adding in an extra energy from an external source to artificially push the environment beyond what it's natural energy intake / output would normally allow. This is why he can have such a large amount of consumers living with a smaller amount of producers. The tank stays relatively clean, b/c as the populations reach homeostasis, they grow to a point where every niche of possible survival is covered. In nature, one creatures excrement is another creatures meal. So, the consumers are producing waste, but the snails are cleaning it off of the tank as fast as it's produced. The waste that ends up in the gravel gets eaten by bacteria as fast as it shows up. Same with the oxygen / carbon dioxide. The plants are scrubbing the co2 as fast as the o2 is being used. This is another control mechanism of the environment. It's not just the energy the environment has circulating around, but also the support systems creatures need. The creatures could only exist up to a point of maximizing o2 use. There could be tons of energy, but if not enough o2, then growth will still be stifled. But, this is where the producers (plants) end up thriving, b/c they take in co2 and and light to make food. So, ramped up co2 levels actually help in feeding the plants. As you can see, there's a lot of "moving parts" to a real closed-loop environment .. plants, bacteria, different levels of consumers, decomposers, etc.. to keep the loop circulating. And it may not be fine-tuned for a specific species that you want to survive. That's why most fish tanks are setup with highly artificial environments to control bacteria, plants, etc to make for an ideal environment for a specific species to survive.

Tony Leon : I found out I am into fish porn and shimp maternity

Its Genji : Some intern at YouTube: “omg this video is amazing, how do I make sure everyone else sees this video too?” Me: “what’s this video doing in my recommended”

Jacob Krom : Why isn’t David Attenborough narrating this lol

Hobbs Charles : This was recommended to me, sometimes YouTube knows me too well.

Your Neighbor Amos : Interesting lol.

DONNASAWR : Am I the only one who went out of their way and selected 1080p quality as well as slowed it all the way down to the lowest playback speed setting just so I can replay back several times, specifically how gnarly that shot is @ 0.45 seconds. So fucking crazy seeing all those little swimmers in a single sac (or whatever it may be that it was - feel free to correct me cause I’m super curious and I’d love to know at just exactly what I was looking at) 🦐 As I’m writing this comment - the video is still playing above in 1080p super slo-mo; along with super creepy/Trippy classical instrumental which is actually somewhat hypnotizing I’m now realizing. ...then again - now that I think about it — it must just be the weed...... ....fuck it. I guess it just makes all this just as much interesting to me versus having to watch this without the use of the happy smoke. I know I ain’t the only one feeling some type of way and zoning out clicking away at the most random videos in suggested videos section and somehow ended up here. But then again - I love when that happens especially landing on a video you would never think or care to look up - but somehow get reeled in and by the end of it - you’ve learned several new interesting facts about the most random, odd but super interesting topics. And before you know it - you unexpectedly find yourself as the life of the party spitting out an encyclopedia of the most useless random info and facts that may actually impress others with your vast extended knowledge containing random facts 101.

Isaac Rè rref : This guy just created an eco system by himself. LET ME REPHRASE THAT. THIS GUY CREATED LIFE. HE JUST MADE LIFE. (EDIT: Almost done with the video, still can't believe it.)

Iivari Loukasmäki : When you get tired of them, you can just release a predator in there :) Would be a brutal but interesting vid.

alejandro jara : I don't normally get interested in these kinds of things, but this was amazing!

Clap clap : Best 8:07 mins of my entire life! I regret NOTHING!!! No sarcasm Maybe I was being a little exaggerated, nonetheless was entertained.

egh wtvr : I feel warm amd peacefull inside.

sudija falkone : Day 200-first sharks are coming out

Hizkia Jeremmy : imagine this is our wildlife, no chemical polution, no mass hunting, only a peaceful life, plants and animals live freely, humans and other creature living together, a balanced ecosystem... I want this peaceful life 😊

Mikeitisssz : Life is beautiful!

James Ultron : Thanos could've kept it under control with the snap of his fingers 👌

HD_POWER : Why u started drinking from the tank at 7:53 ?

Paul A : Either it isn't stated or I missed it, but what creatures did you actually start with? Awesome video, great choice of music.

KNIGHT RIDER RAJIB : YouTube recommendation. I don't know why But it's beautiful

Salim Kabbani : Now do a 6 months eutrophication tank experiment, it will be horrifying but I'm just curious to what will the tank look like after 6 months

Valentina Guadalupe. : My mother Earth needs this

pranav patel : Most satisfying vdo of the year

Ahmad Syawgy : Thank you for making this stress release video

RobertIDK : The fact that you filmed this on a $200 phone blows my mind

Yunus Emre : Why climate change happenning, how to stop it. Sun energy hits the Earth and leaves some energy on Earth. Some of that energy becomes Earths electro magnetic field. Electro magnetic field is basicly electric. We are living in electric. If your electric and Earths electric is same amount; that electric doesnt hurt you because same amount of energy, yuno44907 ignores @ each mail other . but com energy always wants to go to the low energy zones. Thats creates winds and climate because energy want to move and become equal at everywhere. But this is not possible because polars are cold, middle zones are hot so wind will be always exist. Humans generate electricity by using power plants. But you cannot generate electricity because electricity is a solid object just like a stone and you cant make electric. Humans are collecting electricity from Earths magnetic field. So wind energy, nuclear energy, thermal energy stuff stuff all comes from Earths magnetic field and using electricity causes deserts at the low magnetic field zones. Magnetic field comes from polars and looks like magnetic field is bended by gravity because magnetic energy doesnt go straight; it makes circles or stuff like that i dont know but magnetic energy doesnt go straight; light goes straight that is difference.

Grady Yarger : Where there is water. There is life

Tassos Tsirigotis : Why does this look like a real-life videogame?

Lavish Life : Its like playing god

Subhodeep Biswas : Hope we are not somebody's experiment too.....😯😯


Nanli : This is beautiful, to have and see an ecosystem in a nano tank.

Leonardo Ignacio : Don't know why youtube recommended this to me, but I ain't complaining though

Tiggertron420 : 🤔😬 2,000 dislikes!?... Damn, misery really does love company smh... Very relaxing video lol watched it twice, back to back.👏👏👏

chandra danuarta : I can feel the meaning of peace

LeVish hunted : I'm not much into watching fish but I can see how people would be interested by this. This was pleasing somehow

Lebron James : So much life going on in just a 5 gallon tank

Vladimir Lenin : Came here by accident, best accident of my life

SmileCow : I don't know why this video popped up in my recommendation list, but it really is interesting though 💯💯👌🏼👌🏼

Justin Y. : In a couple of days a shark is going to come out of there

Dylan Mengell : That was the most beautiful shit I have ever seen

Marvelle Banks : This was amazing to watch!! Thanks for publishing! One question: how come the baby shrimp never get any larger? are they getting eaten by the fish, or are you removing them? Also, if they are reaching maturity in larger numbers and it is just not seen on camera for whatever reason, what do you plan on doing with them?

Glitched : Wish this was in 4k, it's beautiful!

John Donrick Zerna : So peaceful and fascinating
