All right, so I heard somewhere else that bettas COULD be kept with other fish.
It made both me and my mother quesy to think about, but then I thought it rather made sense -- if the other fish don't look fancy, aren't small enough for food and aren't big enough to be threatening.

However, I figured PT would be able to answer my problems.

I've got 8 various tetras hanging out right now. They've been healthy for two months and according to my fishie biologist (literally, that's what her BS is in) mother, their water quality is good. Should the betta go in a seperate tank or would it be ok for it to go in the same one?
