Sorry for the loss. But any large pim. cat will eat whatever will fit in his mouth. That is why you can't put smaller fish with them. If you are going to keep other fish with these kinds of cats, then they have to be much bigger in diameter than their mouths. Like a large Datnoid, aro, stingray, perch, etc. Not only that but most large pims are territorial and if you put a smaller cat with them, well you see what happens twice now.
