Catfish

The Catfish is the most common river pool fish. Selling for 800 Bells, the catfish is the second least expensive river pool fish. It appears from May until October and from 4pm to 9am. In the Bugs and Fish window in City Folk, it says; "These nocturnal carnivores are also cannibals, so they're hard to farm-raise."

Upon donating to the museum, Blathers will say;

"I've heard some claim that these fish taste a bit like eel, you know. If you want to sample it, , I'd recommend panfrying it. Indeed, I believe you could deep-fry a rock, and I'd enjoy it, wot!"''

In City Folk
Upon donating to the museum, Blathers will say;

"Catfish are known the world over for their voracious appetites! They'll try to eat anything in one bite, up to and including things the of their bodies...or so I hear! The largest of these hungry fish can grow up to 40 inches in length... Imagine going down to the river and having one of those behemoths come at you! The horror!"

It can be found in the middle-left tank in the aquarium.

Further Information
Catfish have one of the greatest range in size within a single order of bony fish. Many catfish have a maximum length of under 12 cm. Some of the smallest species of Aspredinidae and Trichomycteridae reach sexual maturity at only 1 centimeter (0.4 in). The Siluriformes are commonly caught in real life, usually in ponds or lakes. In some fiction, it plays a pun on the name 'Catfish' by making it have the head of a cat. In some parts of the world catfish are eaten.
