Species Profiles
Kuhli Loach
Pangio kuhlii
Kuhli loaches are eel-shaped, nocturnal bottom dwellers with striking black and orange/yellow banding. They are shy, peaceful, and love to burrow in sand and hide in tight spaces during the day. Despite their snake-like appearance, they are completely harmless community fish that become much more active and visible when kept in groups.

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.
