terminalMTS;2603360; said:what are the tankmates? that behavior is typical of a fish trying to surrender. if you have other aggressive fish in there, one or more could be attacking your fish. even at a young age, some fish get very aggressive. watch closely to see. check for ammonia and nitrite. fish often gasp at the surface if they have been exposed to nitrite. i am only guessing, but i would think aggression is the problem
