Is there anything tiny enough to school in a 5g?

you could get 4-5 neon tetras, but I don't reccomen dit since they should have moree room and a larger schools.

I reccomend you just get either a betta, dwarf gourami, or dp and 2 otos.

What would school in a 10g?
I just noticed that hoods for one are only about $25-$30.
