adding more tetras ...

[lyric112209]

So Ive got 4 neon tetras, if I were to get more would those tetras school with the ones already in the tank??

I would think so. If they're the same fish they should school together. Maybe not right away but once they get use to the new surroundings

Same (and sometimes similar) tetra species will school together. No tetra will school with all others.
