Good Schooling fish for 55 gal

[k0y0te]

try some Bala Sharks

I though bola sharks got too big for a 55????

i would go with a type of Rainbow fish.

Id say barbs or Cory's for sure. but if you want bigger fish and smaller schools columbian or bala sharks. I have a school of barbs 2 tigers one green tiger and 2 rosies. the different varieties seem to school together with no problems. So id get a big school of barbs of several different varieties such as golds cherries tigers rosies etc....
