if you're talking about the safety of a male betta (the kind with long, flowing fins) with other fish in your tank...
male bettas WILL attack most fish of similar size and appearance. But ive seen bettas go after fancy goldfish the size of tennis balls.
also, be warned that a male betta is an easy target of fin nippers. the worst fin nippers are generally schooling fish like tetras and especially tiger barbs. ive also had bad expieriences with danios. when a bettas tail is bitten, his delicate fins can be ruined by painful fin rot. And he may fight back, especially if the nipper is smaller than him.
female bettas are usually fine in a community tank. but, to be on the safe side, i would keep a male betta in a separate tank, maybe five gallons. you can really show them off that way.
but in case you're curious, no, bettas don't really have natural enemies in the wild, just male-to-male fights.
Other bettas: they will fight until one dies.
Large fish or other predators: the betta will become food.
Fast/aggressive fish: they may chase it around and start tearing up its fins because bettas don't move that quickly over long distances.
Fish that have brightly colored and long fins: the betta will probably think it is another betta and bite it.
So, there aren't a lot of other things bettas should be kept with. They're territorial and aggressive, but slow targets. Small peaceful fish like some tetras, platys, mollies are okay, as are snails, African dwarf frogs, and small algae eaters.
Betta fish fight will all fish. Even their own kind. If a betta has babies there is a good chance that they will eat the younglings. Betta babies are not born in the egg. They come right out as very small fish. Do NOT mix betta with betta or any fish.
each other and any other fish that comes in its territoy
Bettas can be kept with most community fish. They will only fight with other Bettas.
yes it is, all animals are predators.
It depends on what species the frogs are. African dwarf frogs (which remain very small) are ideal tankmates for female bettas provided the tank is filtered and large enough for all the occupants. African clawed frogs are fine while young, but grow quite large and will eat the female bettas when fully grown; when grown they also need a much larger tank than the average betta sorority.
yes
yes you can it just they will breed together.
Boy bettas have really big fins and are very colorful, and girl bettas are pretty much the opposite!
Bettas originate from Southeast Asia.
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!
bettas are very territorial fish, the males fight for their territiory.
the same as all the other 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
They see them the same as other male bettas,as competition,they cannot tell the diffrence between their reflections and other bettas.
Bettas won't spawn at all if there is not a bubble nest.
No.
