Species Profiles
Serpae Tetra
Hyphessobrycon eques
Serpae tetras are vibrant blood-red schooling fish with a distinctive black comma-shaped marking behind the gill plate. While beautiful, they have a reputation as fin nippers — especially in small groups. Keeping them in schools of 8+ in a spacious tank significantly reduces this behavior. They add bold color to community tanks when kept properly.

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.
