Species Profiles
Betta Fish
Betta splendens
The Betta fish (Siamese fighting fish) is one of the most popular freshwater aquarium fish in the world, known for its stunning flowing fins and vibrant colors. Males are territorial and should be kept alone or with carefully chosen tank mates. Despite their reputation as low-maintenance fish, bettas thrive best in heated, filtered tanks of at least 5 gallons.

Zebrasoma flavescens
The yellow tang is the most iconic reef tank fish — a solid lemon-yellow disc that constantly grazes algae across the rock work. They are active, hardy, and excellent algae controllers for reef tanks. However, they need large tanks (75+ gallons minimum), can be aggressive toward similar-shaped fish, and have become significantly more expensive following collection bans in Hawaii.
