Hi everyone! This is happy face (I don’t know if it’s a female or male) but he has a dot in his cheek and they look bruised. I’m wondering if it’s Gill disease or something else? My water parameters are perfect. Sand substrate, lives with angel fish, not aggressive, feed him cichlid sinking pellets, flakes, and blood worms and frozen shrimp. What is it if it is anything and how can I treat it? Also I am currently in PR for a couple weeks and I need to find a company or someone to do a water change for me in Orlando FL. Can anyone recommend one for me?
