how often to clean a siamese fighting fish tankDamaging biting during subsequent fighting was dramatically decreased in fish which were surrounded for a couple of weeks by conspecifics, though the overstimulated fish conducted only opercular and fin shows to the fish surrounding them, not biting. The latency to opercular demonstrate was diminished, however the rate once opercular reveal began was not significantly various. In the 18 encounters accompanied, a socially overstimulated fish never ruled a control fish. This result suggests a visually mediated mechanism, which reduces biting tendency when there is extended, inescapable visual exposure to mildly aggression liberating stimuli akin to those which cause biting in live encounters. There are a number of species in the genus Betta, however the best known and most excellent is the Siamese Fighting Fish; Betta splendens; the splendid Betta. This fish comes from Thailand and the old name of Thailand was Siam.
