The fish arrived quickly and were very active in the tank. The purple color is striking, especially against dark gravel. My tank looks much more vibrant now. Easy to care for and peaceful in groups.

I’ve had several rasbora varieties before, but this purple variant is truly unique. The fish swim together in a lively fashion and the color contrast is excellent. Great addition to a community tank.
