Fish Fanatic
Just returned to fishkeeping after many years away,I was given a fluval edge as a xmas present,set it up this weekend,I was thinking of starting a Killifish tank,any suggestions from anyone on which species,how many could I keep in such a small tank[21 lts].
The second, and IMO more suitable species is the Lampeye Killifish. It's much less sensitive than the Clown Killifish and can look great in a slightly dim tank. Note that the Lampeye Killifish are shoaling fish and should be kept in groups of 6 or more. The more the better as they will shoal tighter and become less shy. Clown Killifish should be kept in pairs or trios but no more than 2 males in the same tank.
