No they can not. Some people call a Betta splendens a Betta or a Siamese fighter or a Japanese Fighting Fish. They are all refering to the same species of fish. They come in both males and females and both are needed to produce any young.
only if your breeding.
the female beta fish is "plainer" than the male as where the male is a darker shade near the face and lighter shade near the tail.
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. If they are left in with the male for too long he will eventually eat them.
If there is a male and female beta fish, the male probably ate them, and those 2 unlucky babies were definitely male. (male beta fish will kill other fish.)
If Japanese male fighting spiders keep fighting eventually there will be EXCTINT
yes they can.
I don't think so.
Fighting Fish do eat each other so, yes
Probly depends on WHAT fish it is
no, physically impossible.
The 'Japanese fighting fish' is another name for the fish correctly named Betta splendens. They only fight with others of the same species. That means you can keep most fish species that enjoy similar environmental conditions with them.
