The scientific name for the Japanese fighting fish is Betta splendens.
There are no fighting fish that come from Japan. I think you are asking about the Siamese fighting fish (Betta splendens). They do naturally have a round stomach almost like a ball. That is their body shape.
Japanese fighting fish are called 'des combattants' or 'des poissons combattants' in French.
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.
青いベタ /a oi be ta/ would mean 'blue betta/fighting fish' in Japanese.
No not really
no. they are tropical fish.
I think the fish you are asking about is the Siamese Fighting fish AKA (Betta splendens). They are tropical fresh water fish.
Fighting fish is their nic-name so they should be kept separate
