Water temperature for a japanise fighting fish?

Answer 1

There is no such thing as a fighting fish that originated in Japan. However there is a fighting fish that evolved in tropical Asia and that is probably the fish you are refering to. Its' proper name is 'Betta splendens' and its expected life span under good conditions is around 3 to 4 years. When kept in the tiny containers some people insist on using to house them, they rarely live for much more than 2 years

Answer 2

There is no fighting fish that comes from Japan, so I am assuming you have been missinformed and are refering to the fish commonly known as a "Siamese fighting fish". The correct (Taxonomic) name for this fish is "Betta splendens". They are very short lived in the tropical rainforests and paddy fields of Thailand only lasting a couple of seasons at best. In captivity, given reasonable conditions of at least a 3 gallon tank properly filtered, heated etc to live in they can last up to 3 or maybe even 4 years. Kept in tiny, cramped, cruel, bowls and jars (as supplied by the 'unconscionable' pet shops) you would be lucky to get one to last out 1 year.

Answer 3

I assume you mean the 'Siamese fighting fish' (Betta splendens) they prefer to be kept at around 75F under normal conditions and 80F when breeding.
