dwarf rasbora? celebs rainbow?
no way, they maybe small but they are very active
what is that? generally speaking any tetra is going to need more room than 3g
oh and whilst I'm here 3g is not a tank it is a vase
Whats wrong with them being active? Surely thats a good thing? Its not a case of a tank being to small, its a case of not doing enough maintenance to keep the water quality good. Qays, seems to know what he's doing, so why not a 3g? The dwarf rasbora is the perfect fish for this size tank. The great Amano himself kept some in a 1lt tank, you just have to do daily water changes.
The platiumn tetra Hemigrammus armstrongi. I have several of these and they are smaller than most tetras and 2 or 3 would be fine, so long as the water quality is kept up.
