My RES, Sammy is showing signs of fungus on his shell ( I think). I've been treating it with betadine and I bought him a better basking light. I keep his tank and filter very clean. But I cleaned his tank very deeply and changed filters even though it was ok. He is about 5" and acts fine, but I don't want this to get out of hand. I love my boy. I've had him about 4 years. (I've been treating him twice a day) TIA for the help!
Also, I have a small RES (about 2") that I saved from the mouth of a rotwoller. He has a shell wound but it's not deep. Can I treat him with betadine as well?
