Black Tang Fin issues

[blstravler]

My black tang's fins are in horrible shape. Pieces are missing all over the place. They don't look like bite marks, but you never know. Other tank inhabitants include a bunch of anthias, a few chromis, and one golden pygmy angle. The only fish I could think would do it is the angle. However the angle does not show any signs of being in a fight with the tang. Then again the tang looks perfect except for his fins.

Could this be a crab or a disease?

TIA

First thing you should always check with a tang problem is water quality.

Test all your parameters and temperature.

I think it might be the angel... I once added a strawberry dottyback in with my black tang. The tang's fins were fine before I added the dottyback but once I added him I saw little rips everywhere in the fins. I never once saw the dottyback nip at the fins or go at the tang. (The dottyback was 2'' and the black tang is around 4-5''). Once I removed the dottyback, the tang's fins recovered right away.

I would remove the angel and see if the tang's fins heal up. Don't want to take any chances and lose a high $$$ fish...

luvtolean-
Way ahead fo you, everything is fine, I've been checking water every third day for a while to see if I notice anything strange, but nothing.

AI3- I am thinking of taking the angle out and see what happens. Now how to I get a small angle out of a 180 gallon reef with a few hundred pounds of rock in it...... I think I just got a headache.
