I was surprised he didn't regurgitate it it's been like 2 days so he would of done it by now. I think that fish really is the devil, if I didn't know better I'd swear as his belly shrinks he's gettin longer. I'm not too worried about the rays though all my fish pay them no attention. I think it's because they don't know what to make of them. They so don't look like a fish so the cats just ignore them. Except the Hybrid who seeks them out to sleep with them. Maybe it's cause I got the Stingrays first and then the Hybrid an they were the only fish in the tank. The Hybrid was smaller then an I think sought them out for companionship, and contiinues to do so.
