Betta's are pretty good with other fish, it's rare that they will fight, maybe with other betta's
Female Bettas if you want them to mate get more then one female betta get 2 to 3
No. Male bettas can be kept in community aquariums, but should not be kept with fish that look anything like they do, or are small enough to eat. A male betta will mistake a guppy for another betta and kill it. Female bettas, however, can be kept with other "betta-like" fish without a problem.
because they are fish
yes bettas do fight for the woman that is y u only puts one male and one female in a tank together. but no more than one male.
only if they eat them or the fry are adults
Only male Betta fish make bubble nests! they make these for the females, who will lay her eggs in it!
No. Male Bettas only fight with other male Bettas.
Bettas will eat baby guppys as will most other fish, but in general, male Bettas will only fight with other male Bettas. They do not fight with other species of fish
tetras, and other non-aggresive fish
If these are male Bettas they should never be kept in the same tank. Male Bettas (or 'Siamese Fighting Fish') are strongly territorial and won't tolerate the presence of another male. You can keep Bettas just about anywhere (a jar will do) since they're a labyrinth fish and can breathe air. Separate your Bettas.
Male Bettas will only fight with other male Bettas. They do not fight with any other species at all.
No, for a number of reasons. Firstly, one goldfish needs at least 20 gallons on it's own. In addition, not only are bettas and goldfish not compatible, but their needs are different including foods and water temperature; Bettas are best as a solitary fish.
Bettas and goldfish
Male bettas should be kept alone. Female bettas can sometimes be kept with other fish, but in a large community tank. Bettas need their space!
keeping multiple bettas in the same tank is not reccomended
Yes all bettas can mate with other bettas. " regular betta fish" there are different types and they can all breed together.
Yes, you can just not have 2 male bettas together.
Most any other community tropical fish, with the exception of any fish small enough for the beta to kill and eat.
