pretty much any fish except their own kind, but don't mix them with fish that may nip their fins, such as tiger barbs.
Generally they will not get along.
they might for a while but soon one will die
Contrary to common belief, bettas DO NOT live in tiny puddles or footprints. Bettas live in rice patties in the far east. These rice patties are the size of the drainage ditches along most major highways, and are stacked next to each other for hundreds of acres. Male bettas often claim entire patties as their territory
It is easier to say what fish Bettas do not get along with. The only fish a male Betta will not get along with is another male Betta. Bettas are slow moving peacefull fish and they get along OK with most species that are not too big (eg.some Cichlids) and are not known for fin nipping (eg. some Barbs).
Provided the tank is large enough to house them all (1 inch of fish needs a minimum of 1 gallon of water) Guppies and Bettas should get along OK.
well i dont. i have a betta and it killed two of my gold fish that i put in there so no sorry :(
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
