The fish arrived quickly and looked healthy. They are very active and add a lot of color to the tank. I’ve kept them for three months and they’re still vibrant and happy.

Great addition to my community tank. They swim together in a lively way and the colors are stunning under proper lighting. Just make sure the tank is well-filtered.
