Easy to set up and maintain. The fish is active and adds color to the tank. It’s peaceful with other fish of similar size and doesn’t cause much stress. Perfect for a beginner reef tank.

Grew well in a 30-gallon tank. It’s colorful and stays active. A bit more aggressive than expected with smaller fish, so I kept it with larger, calm species.

Great addition to my reef setup. Simple care, hardy, and stays healthy even with minor water fluctuations. I’ve had it for six months and it’s still vibrant.
