Thats actually him flaring out against a mirror in some of the pictures though the end of his tail is a bit translucent butterfly sort of pattern with purple on the inside. He's actually a rescue and have had him since he was even tinier... so far he's grown well but is very courageously timid whenever new objects come by his tank. He pulls in his tail whenever he is curious about a new object and swims to it then flairs back out when he realizes its safe and gets comfortable.. And yes its heated. Usually without any interference his tail always appears flared as with the pics in the mirror.
