Will different breeds of tetra school/breed together?

Question

I want to get 5 neon tetras and 5 black neons, will they school together?

Answer 1

They may jump together if startled, but the chances of them staying in a single school for a long period of time are low.  Just expect to see two fairly separate schools that may swim together once in a while.

Answer 2

Some different species of tetras may school together. However, they must be around the same body shape and size. And it is not a difinite but it has been known to happen.
