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.

The blue tang — Dory from Finding Nemo — is one of the most recognizable marine fish with its vivid royal blue body, black palette marking, and yellow tail. While stunning, they grow large (up to 12 inches), are highly susceptible to ich, and need tanks of 75+ gallons. They are not beginner fish despite their popularity following the movies.
