The fish are very active and add a lot of color to the tank. I kept them in a group of six and they swim together beautifully. Easy to care for and feed. The colors are vivid and they stay healthy after a few weeks.

Great addition to a community tank. They are lively and enjoy the water movement. I feed them a mix of flakes and frozen foods daily. They do need a group, so I made sure to keep at least five.

The rainbow patterns are stunning. They swim in tight schools and are very easy to maintain. Water parameters are stable and they adapt well to the tank conditions.
