Clown, Black Percula missing tail. Certain death?

[fdiddy]

I've had a clown that was being kept in the sump make it into my pump (only 300 gph at the time) and lost most of his pectoral fin and tail. He also appeared to have back problems (Runs in the family ) but he's fine now... well he swims fine and he made a full recovery.. even after swimming on the bottom with a hurt back for two weeks.. GL
