I have 3 tangs in my tank that have been in there for a couple of months. The sailfin gets these tears in his dorsal fin that are usually about 1 inch. The tears heal completely in under 2 days everytime. He has doubled the size of the other 2 in the last couple of weeks. Is there a reason that this tang is growing so fast, his fins are huge siloweted in the tank he looks like a batfish. Has anyone ever had similar experience with sailfins dorsal fin tearing or ripping during growth?
