any good, non-fin nipping, schooling fish, that are only about 2 inches?!

Or, they don't even school!
How many are you planning to keep together? Six fish vs. twenty fish makes for a very different "schooling effect"...

Rasboras are some of the tighter schoolers, but what are the fish that will eat them that you are planning on keeping in there? Personally, I don't think any 2" schooling fish should be in a tank with fish that would eat 1" schooling fish. Common sense.
 
Truthfully don't think that ANY of my fish would do that. I've kept some 1/2 shrimp in there with no consequence! But, just to be safe, it seemed like a 2 inch fish would be perfect. Especially because my leporinus is only supposed to get to be at most 7 inches, but some people say they will still try to eat smaller fishes, or grow to be a foot, but that is only specific types of leporinus. Must be specific fish though that will try to do that, because mine doesn't bother anyone, not even my 1 inch cockatoo cichlids. Although I think my little rosy barbs are going to have to go, because someone keeps trying to shred my angels fins, and I'm not sure who would do that, but they seem like a good culprit. Hmm... Maybe I'll just post a question on it. Oh, and I'm planning, depending on the size of the fish, to keep about 5-6 in there.
 
I don't blame you, I almost got him myself for my yellow lab (mbuna) tank once :) I decided against it after reading the reports of their aggression, but hopefully yours is a mellow one!

By the way, that's "grow older" not "grows older" up there...stupid typo, lol.
 
cardinal tetras, rummynose tetras, harelquin rasboras

These are real good suggestions - none of them will likely get eaten by other fish, ( at least most others), and they do school well - there are others too., such as Lemon Tetras, Amber Tetras, and especially the Rasboras - I really like the Copper Rasboras.


Schooling fish will swim in tight formation, making movements almost in unison. When they agree just hanging out, facing different directions, buzzing around as individuals, then they're just swimming together.
At least that's how I understand it.

Can't think of a better way to describe it !
 
Yah, I really like the Rasboras, the glolites are pretty too. Not to be ignoring all the suggestions above, but has any one ever kept black winged silver hatchetfish? I saw a normal silver hatchetfish at Petsmart the other day, and really liked it. The rasboras are plan B right now!
 
Hatchets are interesting but IME they don't school too much. They are usually fairly spread out in the upper parts of the tank.
