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.

Phenacogrammus interruptus
Congo tetras are the showstoppers of the tetra family. Males develop spectacular flowing fins with an iridescent rainbow sheen that shifts from blue to gold to green under aquarium lighting. They are larger than most tetras (up to 3.5 inches) and need a spacious, well-planted tank to display their full beauty. Peaceful but shy — they thrive with calm tank mates.
