Species Overview

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.

Neon Tetra

The neon tetra is one of the most popular freshwater aquarium fish, known for its iridescent blue and red horizontal stripes. Native to blackwater streams of the Amazon basin, it thrives in schools of six or more.
