Species Profiles
Cherry Barb
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.
