Species Profiles
Otocinclus Catfish
Otocinclus spp.
Otocinclus catfish (otos) are tiny, peaceful algae eaters that are incredibly effective at controlling soft green algae and diatoms in planted tanks. They are the gold standard for planted tank algae control, often preferred over larger plecos. However, they are somewhat delicate and require established, well-maintained aquariums.

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.
