Hey man, I’ve never been bothered by intimidating looking fish such as sharks or gar (Gar are my favorite). Not piranhas, Goliath tiger fish or barracudas etc etc ad nauseum.
Catfish. Holy shit, catfish.
They are tasty sons of bitches when you fry them but once you see one swim up to the surface and casually slurp up a bird you are never the same again.
Mekong Catfish, Wels Catfish and Goonches are fucking horrifying.
