don't go with a betta splenden (siamese fighting fish), they're not community fish at all. they're either the bully or the victim. tetras would rip their long fins to shreds, and i had one that would have great fun trying to pick off my corys eyeballs (they were seperated pretty sharpish)
I completely disagree. Betta's are community fish! From my own personal experience (look at my profile) I keep my betta with barbs, tetras, cories etc. and he's fine! I agree, each betta is different but I think a betta with neons/cories is fine and I would quite happily take full responsibilty if it went wrong.
Bettas are not the best community fish.
Sure, you can put them with other fish, often with no problems, but other times....
I say why chance it? Bettas always seem happier on their own, and it's not hard. Also, filters usually bother bettas with the current, so if you keep the betta in his own tank, you can skip on the filter. Standing water's best for a betta.
