Schooling fish

[Drock169]

I second the choice for the bar/zebra gobies, and you could mix in some scissortails with them. Both choices are jumpers though. Chalk bass will also form small groups. Generally I just tell people to give up on the idea of schooling stuff, its just not practical. You can also look into the mini dartfish, they max at about 1 inch. A. megastigma and T. collini, i think are the names, common name is something like tiny dartfish.
