Truly Nanofish

[black_knight]

I started a list of some truely small fish available in the hobby. So if your looking to stock that 2.5-5 gallon here are some candidates. Though those on the bigger end may benifit from larger quarters. I chose 1 inch as the cut off for schoaling fish, as these do better when stocked 6 or more. For nonschoaling fish 1.5 cm was about the cut off. And yes there are larger fish you can keep in small quarters, but this is my cut off. I'll add more to the list when I can verify more max sizes on other species.

Re: Truly Nanofish

Corydoras hasbrosus and corydoras hastatus are great candidates as well. Similar size to the pygmaeus
