Schooling Fish for 15gallon Community Tank?

Copeland's tetras are what I have... if you can find them, though. I have 6 in my 15. They're pretty rare tho, but it's another option. :) They are closely related to bleeding heart tetras.
 
no not the numbers...why stick with the neons? wrote that in response to mostlycichlids
 
Because ifv you go with another species of schooling fish then you are going to be adding at least six more fish...IMO you really need a few more neons...In the wild schooling fish like tetras school in groups of hundreds. If you get another species of six then you will be overstocked in my opinion....I would just add to the group you already have and make it a large school rather than have two small schools.
 
well if I add another type of fish I'd be replacing the ones that I have....not having 2 types
 
Gold tetras stay small and are pretty. Mine don't seem to school super tight though. Harlequin rasboras are small and school tightly and are very common/inexpensive.
 
if i were to mix cardinals in with neons would they school together?
