Although they may not kill other fish it is not a good idea to put them in a tank with other fish with flowy tails such as guppys or sword tails. The take the tails as another male betta and will be very aggressive towards them causing stress and illness and possible death.
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.
'Japanese fighting fish' 'Chinese fighting fish' 'Siamese fighting fish' and 'Betta' are all names given to the 'Betta splendens'.
Japanese fighting fish are called 'des combattants' or 'des poissons combattants' in French.
78-80 degrees they are tropical fish
Japan
青いベタ /a oi be ta/ would mean 'blue betta/fighting fish' in Japanese.
No not really
No, a betta (fighting fish) is best as a solitary fish due to aggression, but their needs are also different with a betta needing tropical temperatures
Hi! feed your fish once a day
they are the same thing
only if your breeding.
