Species Profiles
Pea Puffer
Carinotetraodon travancoricus
Pea puffers are the smallest freshwater pufferfish in the world, growing to just 1 inch. Despite their tiny size, they have big personalities — they are curious, intelligent, and surprisingly aggressive. They are best kept in species-only tanks and require live or frozen food.

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.
