Hello! I need help trying to figure out what’s wrong with my Pac-Man frog. He’s a little over a year old, I keep him in a ten gallon tank with coconut fiber mixed with a bit moss, and feed him twice to three times a week. Today I noticed a somewhat large clear cyst on the left side of his butt. I looked all over and I can’t find anyone else who has this same issue. Please help me identify it!
