Thread: Irridescent Shark
11-05-2012, 12:48 AM #1
I have a irridescent shark that is about 12" and he one has half of his upper tail fin, it was this way when I got him. He has had the top of his tail fin start to turn red, and a pretty deep red. He is eating fine, acting normal but it is red, no other problems or marks on him. Is this normal, is this stress maybe because I did change up the tank recently. Any ideas?
