I think the fish you are asking about is the Siamese Fighting fish AKA (Betta splendens). They are tropical fresh water fish.
A Siamese fighting fish/betta? Yes! They cannot survive in salt water.
no. they are tropical fish.
The scientific name for the Japanese fighting fish is Betta splendens.
No, any additional animal put into a confined volume of water will increase ammonia levels and will therefore not keep water 'fresh'.
Japanese fighting fish are called 'des combattants' or 'des poissons combattants' in French.
No idea but I know that they live in fresh water and come from asia!
