Hi guys! my dragon scale betta has a discolored white patch above his left eye and on his dorsal fin. it started around 2 3 months ago and I didn't think anything of it at first but now it's getting worse! it looks swollen now and I went to petsmart to have them tell me what they thought it was and they just gave me some bettafix. I put it in the tank and it didn't do anything so I did a full water change and put some sea salt in his tank because I didn't have any aquarium salt at the moment. it's been about 3 days since I put the salt in and I see no difference in his fungus or whatever is on his head. what should I do? I don't want him to die and i've had him for around 6 months now and I was planning on getting him a bigger tank soon. I need like a professional opinion here on what I should do. heres a pic. let me know what you think I should do guys! thanks.
