Let's answer this question slowly: Is a cory catfish likely to eat another living fish?

User
The cory catfish is a fish that is described as a bottom feeder. The cory catfish feeds on food located at the bottom of an ocean. Fish cannot live too deep in oceans for very long because of the intense water pressure. The bottom of oceans is populated by algae, coral, and microorganisms. So the answer is no.
