So I recently noticed that my two half-moons, Merry and Pippin, both were getting what looked like fin rot on their tail fins. At first I thought maybe they were biting their own tails, but just about 10 minutes ago, as I was watching them, one of my ghost shrimp swam up, grabbed hold of Merry's tail, and literally tore a chunk off. It was horrible! Needless to say, I immediately removed all the ghost shrimp.
Has anyone ever had this happen before?? I'm afraid to put the shrimp in any of my other tanks, I don't want anymore tails being hurt.
