I am slightly concerned about 2 of my barbs. They have some odd growths on them. I am concerned they are parasites but they do not look like anything on the web that I have found. The fish are behaving normally and do not appear sick. If this is something, I want to hit it early. Should I treat with an antiparasitic just in case? Any advice would be much apreciated!
(In my not so expert opinion, they do not look like anchor worms)
