Charles Scott –
Easy to set up and very peaceful in my 30-gallon tank. It spends most of its time digging in the sand, which adds natural movement. No aggression or issues with corals. A great addition for a beginner reef setup.
Alexandra Piper –
This goby has been in my tank for three months and remains active and healthy. It doesn’t disturb the reef and enjoys the sandy substrate. Perfect for a calm, low-maintenance community tank.
Tracey Terry –
The fish is active and curious, especially when the sand is disturbed. I appreciate its peaceful behavior and how it blends into the environment. A little shy at first but settles in well.
