Species Overview

Common Goldfish

The goldfish was one of the first fish to be domesticated, with selective breeding in China dating back over 1,000 years. Despite common misconceptions, goldfish can live 10-15 years with proper care and require far more space than a small bowl.

Dwarf Gourami

The dwarf gourami is a brightly colored labyrinth fish native to the slow-moving waters of South Asia. Males build elaborate bubble nests at the surface for spawning. Its pelvic fins have evolved into long, thread-like feelers used to sense the environment.
