one of my fish a yellow tail blue damsel which i have had for over two years has suddenly begun to swim upright seems to have difficulty getting horizontal, i have seperated him from the others in the tank and when i feed him he eats well. is this condition treatable? the other fish in this 55gal tank seem alright, they are a bicolour, a coral beauty, and a maroon clown, all have been together for two and a half years.thanks for any advice you can give me, malmar, ontario, canada
