So i have had this guy for a year now. He used to beg for food. Eats pellets,shrimp, snails when he wants to. For past few weeks he acts like he wants to eat but can't. I thought it may be his teeth so i used clove oil to sedate him. Looked at his teeth and they weten't that bad. I trimmed them a little. It almost seems like there is to much skin around his mouth. I also took notice inside his mouth there is like a white thing that was soft and inflated. Almost like a small ballon behind his toungue. It seemed to deflate and inflate. He has no problems swimming and water parameters are fine. Ill attach pic but it is hard to see. Any ideas? I don't want to lose him.
