Pics are quite dark to clearly see but appears as a bacterial growth which would cause the pause in feeding. Treatment will have to be performed in quarantine using Seachem Kanaplex whjich is a broad spectrum treatment easily absorbed by fish and addresses Mouth rot. Other option is Maracyn 2 but I prefer the seachemPlease help what treatment is required for my angelfish. The growth appeared very fast and is stopping it from eating. I am dosing primafix and after 3 days no improvement. It almost looks like cotton wool. The treatment says it treats fungal infections.
The lights are off aT the moment, injury I can only think it could have come from the head section of a shrimp I fed. I've had the fish nearly 4 years now.
