i am looking for a predatory fish that will live alone and will eat the occasional f/t mouse/rat that my snakes dont eat, i have thought about a wyckii (i'm guessing they would eat the occasional mouse?), micropeltes or similar snakehead, aba aba knife (not sure if i can find 1), gar (least favorite on the list but still a cool fish that i would enjoy keeping), or anything else you think will be good? i'm not really interested in pirhannas or cichlids but i'm open to any other ideas
