Cuisine & Edibility

Not consumed — a prized ornamental aquarium fish known as the 'king of the aquarium' for its disc-shaped body and brilliant colors.

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
Discus
The discus is often called the 'King of the Aquarium' for its disc-shaped body and stunning color patterns. Native to the Amazon floodplains, it requires warm, soft, acidic water and feeds its fry with a mucus secretion from its skin.
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.
