I got my betta fish, Tsunami, about 4 months ago. When I first got him, he had fin rot which I treated with Imagitarium Bacterial Infection Remedy which seemed to have worked as his fins are growing back now. Recently, (about 2-3 weeks ago) I noticed that Tsunami had popeye. Only one of his eyes was swollen. I treated him with the same medication and the swelling went away. However, I noticed that some of his scales were still a little bit discolored and were slightly white. The scales seem to, for lack of a better word, puff out. I have noticed him rub himself against the little nerite snail he shares his tank with, which makes me think the scales could be itchy. I’ve attached a photo where hopefully everyone can see the discolored scales on his head. I would love to know what is wrong with him and how I could help him. This condition has been around for a while and it doesn’t seem to be bothering him too too much but I’m afraid it could worsen. Any advice or suggestions would be appreciated!
