i just recently am on the downslope of fighting off some ick, thanks to all for the great advice and the reading that i've done here! my question is now on my irridecent shark. he seems "cracked" i know this is a strange description, but it seems as if he is shedding almost. he acts fine, but his skin just looks weird. like i said, its almost as if he's shedding the current skin that he's got. i'm curious if he has some kind of infection or if this is normal for this type of fish. thanks.
