I have had my true percula clown for 4 months now. Today I noticed a few black spots on his sides. One is close to his side fin and some are just on the side of his body. It kind of looks like he has been stung by a coral. The only thing that I have that could sting anything would be a frogspawn. I have never seen him laying in it before! If he is laying in it at night could that be the cause of the black marks? Anyone have a link to some information? I don't want to lose my fish
Thanks in advance!
