I have a 20 gallon reef set up with a clarkii and percula. There's about 40 pounds of live rock, various coral, BTA, and CUC. I'm wondering if I could house a yellow watchman goby in there too. I understand they primarily stay on the bottum in their cave. Would it get along with my clowns? Is 20 gallons big enough?
