maroon clown

[j_hammer]

my maroon clown has got a white stripe on the top of its head looks like flesh is missing what would cause this, there is a damsel in there that a little agressive but i have never seen the two off them close to each other, what could i use to get the clown back in shape, i have some vita chem says good for fin regeneration. i'll try to get a pic of him tonight he eats good and swims around good to. thanks jason
