Species Profiles
Congo Tetra
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.

Puntius titteya
Cherry barbs are one of the most peaceful barb species, making them ideal for community tanks. Males develop a deep cherry-red coloration when mature and in breeding condition, while females remain more subdued with brown-pink tones. Unlike their more boisterous relatives like tiger barbs, cherry barbs are gentle, shy, and compatible with even the most delicate tank mates.
