The colors are vibrant and the fish are very active. I kept them in a 10-gallon tank with compatible species. They seem healthy and enjoy the environment. Great addition to a community tank.

Arrived quickly and the fish were well-packaged. They’ve been in my tank for two months and are still active and colorful. I’m happy with the size and appearance.

The fish look impressive, but I noticed they get territorial. I had to keep them alone. Would recommend for experienced aquarists who understand betta behavior.
