Betta Fish mixing with others in 20gal? Is it safe?
I have a female betta fish, 1FW molly, 3Guppies, and 1Blackskirt Tetra(i will rack up on these guys later). And don't forget the two baby mollies that will be added once they get bigger, and once i feel they wont be sucked up by my filter :( Anyway,I got a 20gal for Christmas, and I was curious if it would be safe for the other fish to move my Betta Fish in there. Its a large enough tank, and I've heard of people putting their Bettas in a 10gallon with other fish. My mom thinks that my Betta would eat the other fish, and I wanted to find out. If not, I have a spare 1.5 gallon she's going to be put into, and I am also getting another Betta, and I think that if I go out and buy another kit like the current 1.5 gallon, that he'll be fine in there. But if I would get a female, could I put her in the tank too? Only if its safe... I've also heard that Whisper Filters are not good for bettas. Should I find another brand of filters? Whisper has been a good brand for me, so should I change now?
Eating the other fish? Defiantley not, unless it is molly or guppy fry.
I would not do it. Even though female bettas have smaller fins, it still has the potential to be nipped by other fish. Black Skirts are *very* nippy, and I have seen a lot of mollies who nip. Bettas do not make good tankmates as well.
Whisper internal or external? The Internals are great, but I have no experience with the HOBs. HOBS generally produce a lot of flow, unless it has an adjustable setting.
