Schooling fish
 

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

chromis?

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.

anything else?

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.

I've tried small damsels and as Chin said they stayed together for a couple weeks then aggression started until 2 were left. I am open also for suggestions.

Pigmy Sweepers...but I can't find them available in the stores. Here's a photo I took of them at the Georgia Aquarium.

I suppose this isn't helpful. I want to find a tight schooling fish also. I've been unable (so far) to find a fish that behaves this way and is also one that I can get.

chalk bass will school, as well as firefish, but the firefish from angry schools like damsel (except fins to go missing)

Will chalk bass actually school or will they only school for a while, like Chromis, then kill each other off (like Chromis)?
