Ok so bought a gar about 3 weeks ago and noticed about a week ago that he had some strange little bumps on him or her. They look like little warts or skin tags to me and the wife, however we cannot find anything on the internet that looks like what he has! We thought it might be lymphocystis or some type of cyst but again cannot find anything! If someone could please identify what it is and if it is dangerous or infectious to our other fish that would be great thank you!
