Schooling fish

[SeaSerpant]

what kind of small fish would be good in a 60g aquarium that school?

[pandafishowner]

chromis?

[justinl]

imo a 60g is too small for any kind of fsh to show any kind of schooling behaviour... you would need a much bigger tank. in a 60g my guess is that a group of chromis would just pick each other off one at a time.

[SeaSerpant]

anything else?

[fmelindy]

maybe some of the smaller schooling cardinals would not be too big of a stretch

I haven't been able to find a type of find that stays schooling after extended period of time in a hobby tank. The natural instinct for fish to school is for protection. When you introduce the school of fish into your tank, it will school because it feels threatened. After a period of time when they no longer feel threatened by your presence, they will stop schooling and often display aggression towards each other. Chromis is one such fish that I've had that will pick on the weakest in the school until one or two remain.
