Spots on Tang

[gmarchetti]

Our little Blue Tang just developed 2 spots on his dorsal fin. One is fairly large- oval and somewhat see through. The second spot is farther back and much smaller. Any idea of what this could be and if it is dangerous to him? I don't believe it is either black or white Ich. The fin is not rotted completley through so I don't think it is fin rot. We've had him for awhile now and I just learned he needs to also be fed seaweed. Could a deficiency be causing this?

Welcome to RF. Your best bet is to go post this at the Marine Fish topics moderated by Steve-S. He'll be your best bet and good luck. Mike.

Welcome to RF!! Bummer on the spots. :doubt: I agree...SteveS would be a great person to ID it, but a pic would probably be needed. Good luck and hope you enjoy the forum
