Species Profiles
Clown Pleco
Panaqolus maccus
Clown plecos are beautiful, small plecos with striking orange and black striped patterns. At only 3.5 inches max size, they are perfect for 20-gallon and larger community tanks. Unlike many pleco species, they are primarily wood eaters rather than algae eaters — driftwood is an essential part of their setup. They are shy, nocturnal, and make excellent additions to planted tanks.

Paracanthurus hepatus
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.
