Not sure I'm going to ask this correctly.

I'm looking into a couple types of fish that "school" (i.e. cory cats and tetras) and was wondering if the school had to consist of all the same breed of that fish type, or if you could mix-n-match within the species (i.e. a school of 6 tetras, consisting of 2 members each of 3 different kinds of tetra).

Probably a dumb question, but one I wanted to ask before I work up stock lists.
 
Cories mix-and-match well when it comes to schooling, but they'd still prefer their own species.

I've seen Neon and Cardinal Tetras schooling together at the LFS, I'd assume that's only because they look similar though.
 
It's each species for itself. A lone cory will welcome another species well, but would prefer it's own species.

Tetras, however, only school with their own species, unless something like a school of neons and a school of cards were being chased or scared, they might school...
 
i had thought i read one time of someone who kept large schools of cardinals and neons in the same tank, and each species pretty much kept together and didnt mass together in one giant blob of red and blue, but ive never tried it, any fish that size that enters my tank is eaten pretty quickly
 
Our harlequins and penguins school together, but i don't think thats the norm........:)
 
I have Harlequin Rasporas, Brilliant Rasporas, Pristella tetras and Neons. I find they normally do not school together but every now and then I will actually see the Pristella's and the harlequins schooling together. Generallly the Neon and the brilliant's keep to themselves, well of course except for feeding time then its one big party..lol.
 
Normally same species school togather and the other outside of that species do not. Cories sometimes will school outside of their own species but much prefer to school with their own kind. IMO schools all of the same species look better then one or two of each.
