The fish arrived healthy and active. They adapted quickly to the tank setup with live plants. Very hardy and peaceful, they don’t stress other fish. A great addition to a community tank.

We’ve had them for two months now and they’re still vibrant. They don’t need much attention and thrive in a planted environment. Good coloration and active swimming.
