I got some new rays and my FRT took a liking to nipping their tails. I isolated him in a floating 30 gallon tub with holes in the side. He was in there 2 days before I moved him in with my larger rays. I noticed today he had these marks on his belly. They look like rub marks to me but wanted to make sure they were not something else. I am not too familiar with any diseases or disease treatment on these. I am just gonna observe at the moment to see if they get worse.
