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.
