The fish are very active and their bright orange color stands out in the tank. They school well and are easy to keep. I’ve had them for six months and they’re still vibrant and healthy.

Great addition to my community tank. They don’t glow, but their fluorescent orange color is striking under regular light. They’re peaceful and don’t bother other fish.
