Hello, I have a mature Flowerhorn cichlid who's lips have become slightly swollen and he seems to have trouble moving his mouth. There is also a small abtrusion or sore on the bottom side of his mouth/jaw. He hasn't been eating for the past two days. I don't know if this has anything to do with it but this situation occurred after feeding him a food called "bug bites" made by the Fluval company. Also, he has a small "dent" on his crown, I guess from hitting his head on something in the tank. Can anyone offer advice? Thanks
