A little white bump has formed on my angelfish's tail. It's not acting any different, and none of the other fish are showing any similar problems. Any ideas what it is and how to treat it?
Nothing to worry about, many angelfish that I've breed over the years have developed the same feature. It's just a fractured spine in the fins, weither it was from a fight or spazzing out and brushing too hard against a piece of driftwood or filter intake tube. It will heal quickly, but the scar will stay for some time.
