I just noticed a scale dangling from his kok just now. He seems to be in normal behavior and still eating. Is this okay? Is there something I should do about this? Im new to FH's and I'm not sure what to do with this... Thanks guys.
He hit his head on something and it peeled a scale off. Perfectly normal with flowerhorns and some other cichlids with large nuchal humps. Give it some time and it will heal. Just make sure your water he's in is clean to minimize any chance of infection
