I have a clownfish, and flame angelfish. 2 days ago I noticed a raised white circular bump on the angelfish's tail fin was too big to be a ich, 24 hours later it was gone, but there was now a circular hole in the fin, yesterday another raised white bump appeared on his anal fin again 24 hours later it is gone again ,leaving a perfect round hole in the fin, anyone have an idea what could be causing this?
