Species Overview

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.

Plecostomus

The common pleco is a large armored catfish native to South America. Often purchased as an algae eater, it can outgrow most home aquariums. Its sucker-like mouth allows it to rasp algae from surfaces and anchor itself in fast-flowing currents.
