These fish are colorful and active in a small tank. I kept a group of four and they swim together nicely. Easy to care for and stay peaceful with other small fish.

The colors are bright and they look great in a community tank. I noticed the males are slightly more vivid, but the females are still attractive. Water temperature stays stable with the heater.

Perfect for a beginner aquarist. They don’t require a lot of maintenance and are very peaceful. I’ve had them for over a year and they’re still healthy and active.
