The Harlequin Rasbora are vibrant and active in my 10-gallon tank. They swim in groups and add a lot of visual interest. The colors are bright and the fish seem healthy after a few weeks. I appreciate the tank-bred quality, which means they’re well-adapted to aquarium life.
Madeleine Dyer –
I’ve had these fish for about two months now. They’re very peaceful and don’t stress other fish. The pink body with the dark markings is striking, especially in a dark tank. They’re active but not aggressive, which is perfect for a community setup.

The fish arrived quickly via UPS Next Day Air. They were healthy and active right after placement in the tank. I love how they form a school and move together. The coloration is vivid and they stay calm in the water.
