I have a 29 gal biocube. Fish wise I have 1 fp clowm and 1 orange spotted goby. Besides the fish i have multiple hermits and snails as well as an emerald crab and sallylightfoot crab. Coral wise sun polyp, zoos, mushroom, ricordea , frog spawn, and some other polyps. I want to add one more fish and i am just looking for suggestions. Here is a couple pics.
