I have a spotted damsel fish that has what looks like a growth starting on the top of his fin above his head. Does anyone have any suggestions to what this might be.
I don't think I can get a picture. He is so fast, but It looks like little tiny white bubbles on the tip of his fin. Seems to be getting bigger. It has been there for a week now. Doesn't look torn or anything like that.
This is what is so strange, it is just located at the very tip top of the fin that is located above his head. No where else is there any sign of anything.
