Male Fighting Fish are very popular tropical aquarium fish, with their spectacular fins and bright colours. Their reputation for fighting other males also arouses much curiousity with males having to be housed separately to prevent them fighting. They are excellent aquarium fish, easy to keep and suitable for community aquariums. Tankmates can be any similar sized peaceful species, but should not include fin-nippers such as some Barbs, or male Guppies (which are sometimes attacked by Fighters). Male Fighters can also be kept singly in glass bowls or similar small receptacles, provided temperatures are not too cool.
