Anna Paige –
Easy to set up and very peaceful in my 50-gallon tank. It doesn’t bother other fish or corals. Grew to about 5.5 inches over six months. Perfect for a beginner reef setup.
Molly Lewis –
Arrived healthy and active. Stays in the middle of the tank without aggression. Needs a stable environment, but once settled, it’s a great addition to a reef tank.
Theresa Sanderson –
I’ve kept this goby for over a year. It’s calm, doesn’t eat corals, and blends well with the rockwork. Very happy with the purchase.
