coral beauty question

[kimbertent]

For the past few days my coral beauty has had a few noticable marks on her and I do not know where they are coming from. Today i noticed that her fins were seperated in two spots, instead of being a smooth fin it was cracked in two spots. anyone know what could be causing this? i just added in an atlantic blue tang but i have seen no agression whatsoever from him towards the coral beauty.

my whole tanks inhabitants:
coral beauty
atlantic blue tang
scalefin anthias
3 chromis
percula clown fish
2 fairy wrasses (the LFS wasnt sure what kind they were)
3 camel shrimp
fighting conch
sea hare
various snails

anyone have any ideas as to what could be causing the spliting of the fins???

See if you can get a picture, it's hard to even hazard a guess without being able to see what the fish looks like.

It might not be anything to worry about. Just keep a good eye on it for a few more days..
