What’s wrong with this fish??? Long story. I’ll try to make it as short as possible. Have a 55gal tank that had a single blood parot fish in it for many years (prob 8). The tank was poorly maintained but the levels never got bad but the ph was always low (low 6’s). Our daughter decided Sushi (yes that’s his name) needed a friend. I cleaned the tank thoroughly and did water changes over the course of about 2 months and got the ph stabilized to over 7 and all other levels were fine. After the water was stabil for a few weeks I decided it was safe to get another fish. We got this large flowerhorn due to the size of our blood parot. They didn’t get along so I put a divider between them in the tank. Fast forward a few weeks and these white spots start developing around his eyes and gills. I put ick medicine in thinking that was it. No luck. The spots grew. I went to the fish store and asked what they thought it was and they said fungus. At the same time I tested the water quality and the levels were crazy. Did an immediate water change and got them down a bit. (Also had an algae bloom in the meantime due to the nitrate spike) Got API fungus cure and did 2 treatments as directed. Pet store said to treat fungus before worrying about the levels. So today was the last day of the second treatment. I’m going to do a water change and put the charcoal back in the filter. The white “spots” are growing. They are kinda “flakier” than they were but def bigger. And I think there are a few more small spots forming on his other side. What could this white stuff be? And how do I get rid of it??? Thank you all in advance!
