Oliver Mackenzie –
Easy to care for and very peaceful in my 30-gallon tank. It spends most of its time digging in the sand, which adds natural movement. No issues with corals or other fish. A great beginner-friendly addition.
Diana McGrath –
Arrived healthy and active. It’s been two months now and still shows interest in the sand bed. Perfect for a small reef setup. No aggression, just a quiet, curious fish.
Kimberly Johnston –
Loves the sand and stays in one area. Tank is 35 gallons, which is above the minimum. It’s not very active but very calm. Good for a beginner with a reef tank.
