Sorry I was talking about self sustaining aquariums. Not terrariums. Got confused for a sec.
My friend who is the current decision maker in our project wants to have Neon Tetra there. Think of basic and common stuff. This is our first go at this.
I mostly want to keep nitrogenous fish waste in control. I found some testing kits on AliExpress for that. I know from high school biology I need nitrifying bacteria in there but I am not sure about which species would work best for my purposes.
Also, plants. Preferably stuff which will help consume nitrates produced by the bacteria and produce oxygen for the fish
We got some random playground sand from outside and washed it real good. I am very skeptical that it will work. We couldn't find anything in local pet shops when we asked about "aquarium sand". Will cat litter work or should we look for aquarium sand on the net?
