Alright, so, I've had my tank for about a year. About 6 months ago I
introduced a new fish to the aquarium (there was just one in it
before). About 3 months afterward, I saw this odd white...."clump" on
the edge of his tail fin. Does anyone have any idea what this is? It's
since fallen off and the fish as matured in to adult hood. However, I
would want to be prepared if it's something that could happen again.
