Species Profiles
Tiger Barb
Puntigrus tetrazona
Tiger barbs are energetic, boldly-striped schooling fish that add constant motion and personality to aquariums. Their orange body with four distinctive black vertical stripes is instantly recognizable. They are notorious fin nippers when kept in small groups, but this behavior is easily managed by keeping 8+ together in a spacious tank.

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.
