No, a 'groupa' fish is not a 'catfish.' A groupa, often referred to as grouper, belongs to the family Epinephelidae and is typically found in warmer waters, primarily in coral reefs. In contrast, catfish belong to the order Siluriformes and are characterized by their whisker-like barbels. While both are types of fish, they are from entirely different families and have distinct physical and behavioral traits.

There are many species of fish that are called "catfish'. The thing that gives them this name is the feelers/whiskers around the fishes mouth. So I guess the answer to your question is. A catfish is a fish that has what appears to be whiskers.
