yes they can live beside each other i have a tank in the hexagon with all of them beside each other. they will try to fight still but that is normal.
All bettas will fight each other, male or female. Always keep them separated.
No, you should never keep a male and female betta fish together for long time periods. They should only be put in the same tank for breeding purposes and then separated after.
no because male betta's are really aggressive to other betta's which plakats are male's. but female betta's can stay with other females. don't try to, one of your betta's are going to end up dead.
other Betta fish and the bigger fish.
Male Betta splendens fight with other male Betta splendens so the answer is most other fish will not fight with a Betta in the same tank. To try to list every species of fish here would be impossible.
becuse thay bite other fish
yes, currently most of all the betta fish come from china. they are found in little ponds with other betta's.
No. Betta fish will attack each other no matter the sex.
Male Betta's are solitary. They cannot be placed with other fish. That's why they are known a Japanese fighting fish. They will kill other fish for territory.
Yes, Betta Fish are extremely aggressive and they will most likely kill your other fish.
yes but only if yours is very hurt by the other betta fish.
There are over 20 members of the Betta family that I know of. They are all small fish and all have the same labyrinthine breathing system. None of them have the magnificent finnage of the common Betta splendens though. Other relations of the Betta are all of the other Anabantids including the Gouramies.
