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.

Paracanthurus hepatus
The blue tang — Dory from Finding Nemo — is one of the most recognizable marine fish with its vivid royal blue body, black palette marking, and yellow tail. While stunning, they grow large (up to 12 inches), are highly susceptible to ich, and need tanks of 75+ gallons. They are not beginner fish despite their popularity following the movies.
