Harlequin Rasbora at Sea Cave Inc.

Freshwater Fish

Harlequin Rasbora.

A coppery-orange rasbora marked with a bold black triangle — peaceful, hardy, and beautiful in a tight school. A beginner favorite; a group shoals beautifully in a planted 10-gallon-plus tank with soft water.

Good tank mates

Harlequins are peaceful and community-safe, so they're an easy fit for a calm community tank. Great matches are other small, peaceful fish: tetras, other rasboras, corydoras, small peaceful gouramis like honey gouramis, and small livebearers. A few real examples are ember tetras, neon tetras, and bronze cories. Steer clear of fin-nippers like tiger barbs and of larger or aggressive fish, and avoid any tankmate big enough to swallow a small rasbora.

Good to know

The harlequin rasbora is named for the bold black wedge-shaped patch on the rear half of its body.
