Yes - I had an aquarium a few years back and had an albino catfish... a few months later, a couple of my fish started disappearing. Then one fish had babies, after they got bigger, we put them with the rest of the fish, and then they started disappearing - to my surprise, I started seeing the catfish eating them. So I figure it must have gotten some of the other fish too.
