Please help, Skywalker has this fungus looking spot on his fin. Can anyone tell me what it is and how to treat it?
In fact he isn't acting different in anyway. He eats his food like a pig, swims around happily, and shows off for me when I put my face up to his tank. I noticed this fungus looking spot when I cleaned his tank and I'm worried it's getting bigger.
I'm not knowledgeable about betta diseases at all. I don't want Skywalker to get sick or die. Please someone help me and tell me what to do!
