Hello, I was wondering if I could receive some advice about my flowerhorn as I have been really worried about him lately. A couple days ago I noticed he had a small bump on both of his sides behind his fins but I figured that he just scratched himself on something in his tank. Since then the marks on his sides have gotten bigger and I am not sure what to do. He is acting like he normally does and is still eating and pooping really good. What should I do, and is this normal?

Sorry for responding so late but the tank is a 15 gallon (small I know but I’m waiting to get a bigger one) and there is no other fish in the tank with him

That’s a pretty small sized tank for the size of fish that or the photo makes the FH look bigger. How regular is your water testing and WC?
