I bought a large crosshatch a little over 2 years ago. He began eating after about a week then would eat any and all prepared foods. I fed krill, silversides, mysis, LRS, and an assortment of pellets. After about 1.5 years I got up one morning for work and he was swimming upside down. When I came home he was dead. He was never aggressive with other fish to the point where my lawnmower blenny pushed him around at times. Great fish but he would smash into my coral at times breaking it so I will never get another fish that size again. My tank is a 220g.
