A few time ago it was uploaded in the channel Michael Langerman, the video “Self-Sustaining Aquarium Prototype Tank”.
As informed by Michael Langerman: “Here you can see my 4 month old self-sustaining aquarium with snails and seed shrimp as it was on January 20th, 2018.
I use this aquarium to learn what it takes to build a self-sustaining aquarium for fish https://www.youtube.com/watch?v=ZrQKfd8T2n4&list=PLM88hGt0AfGvTwxtpc8005q8jwWelt_Yc
In this prototype, I made holes in the upper part to provide access to atmospheric air while reducing water evaporation.

January 30th, 2018
I punched more holes to check if it would make any difference.
February 7th, 2018
I moved a 5 month old female guppy, born in August 2018, into this aquarium.
This aquarium became a testing ground for a number of ideas that I will talk about in future videos.
May 6th, 2018
The water level has dropped a few millimeters in the prototype tank in the past 3 months compare to about 2 cm in my open top aquariums (though, I keep them covered).
Also, I added a male guppy and plants https://www.youtube.com/watch?v=Ms9D7_xyvPQ&list=PLM88hGt0AfGvdY1rnqapi-0wLa0LUFgSG
June 4th, 2018
I added Elodea https://www.youtube.com/watch?v=5zJN7hyjzhY&list=PLM88hGt0AfGt6Kve9jdKNtoph6X-Na8cf
July 25th, 2018
The water level dropped few millimeters.
December 17th, 2018
16 months passed since the initial setup of this prototype aquarium.
I doubled the number of holes about a year ago.
Let me shake it a bit for you to see the water level.
For all the time water level dropped…he-he…about 1.5 cm or about 1 mm a month.
This aquarium can stay without a water refill for a couple years 🙂
The layer of algae on the walls of the tank prevents to see the beauty inside…
Let’s take a look from the top.
Here you can see the fish and all the way to the bottom.
In future videos, I will share about other things I have been doing in this and other aquariums to make small self-sustaining aquarium for fish.
Have fun and happy aquariums 🙂
