Cuisine & Edibility
Corydoras
Not consumed — a small ornamental bottom-dwelling catfish beloved for its peaceful temperament and role as a substrate scavenger in community aquariums.

Delicate, subtly flavored white flesh with a unique gelatinous texture; poisonous organs contain lethal tetrodotoxin. A Japanese luxury delicacy — preparation requires licensed chefs only.
Species Overview
Corydoras
The peppered corydoras is a peaceful bottom-dwelling catfish native to South American rivers. It uses its barbels to sift through substrate for food and should be kept in groups of six or more. It can gulp atmospheric air in low-oxygen conditions.
Japanese Fugu
The Japanese pufferfish, or fugu, contains tetrodotoxin, a poison 1,200 times more deadly than cyanide. Despite this, it is a prized delicacy in Japan, where specially licensed chefs prepare it as sashimi, hot pot, and grilled dishes.
