I have a hippo tang that's about 7 inches from nose to tail. Recently she has become VERY aggressive. She's killed a fairy wrasse that had been a tank mate for 3 years, a female Japanese swallow tail last week, and this morning she killed my 5 inch gem tang. Needless to say she has to go. Ive had her since she was the size of a quarter. The gem took a beating. Found it mauled pretty badly between the rocks. They slept in pretty close quarters..
Im pretty ticked off. The gem was fat, healthy..
Do hippos get aggressive as they age?
