Yes they will. Male Bettas will fight if they are in the same aquarium with another male Betta. Other than by separating them, there is nothing that can be done to stop them fighting. They have evolved over millions of years to do this. A Male Betta is OK with all other species of fish but he will fight another male Betta on sight. He will attack and kill a female Betta too if she doesn't spawn with him. Even if she does spawn with him, she will be killed as soon as spawning is over if she is not removed from his tank. Several female Bettas can be kept together OK. It is only the males that behave that way.
some times but not often and its a good idea to get the same coler.
yes, i have 2 female Bettas in the same bowl and they act as if the other betta weren't there
Generally they will not get along.
they might for a while but soon one will die
Yes,but those betas can not have baby's together!
2 female Bettas will not fight provided they are in a large enough aquarium.
Yes. Female bettas of all ages can live safely with other female bettas. Female bettas, unlike males, are not violent. Actually, they are quite docile and calm.
His gills will flare up.
Betta's are pretty good with other fish, it's rare that they will fight, maybe with other betta's
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!
A female Bettas body length excluding the tail fin is around 1.5 to 2 inches.
Likely, cories and less aggressive bettas such as females generally get along, but it really depends on the individual betta's temprament.
Bettas are agressive towards smaller fish, so neither.
Bettas should be kept at around 75F to 78F.
