Easy to set up and very peaceful in my 40-gallon reef tank. It spends most of its time digging in the sand, which adds natural movement. No aggression or issues with corals. Great for beginners.

Arrived healthy and active. It’s a nice addition to my tank. I didn’t see any signs of stress or territorial behavior. The size is small, but it’s active and interesting to watch.

Perfect for a beginner reef setup. It’s calm, doesn’t chase fish, and blends well with the sand environment. I’ve had it for three months and it’s thriving.
