Yes. An API Saltwater Aquarium kit. Will a Sandstar really clean the crushed coral? I tried a goby but he died. I think it was a bad buy bc I have a Flame Pygmy Angel, Coral Beuty, Clarki Clownfish, Regal Tang, and a cleaner wrasse. Also 2 cleaner shrimp with assorted hermit crabs and snails. Ilso have a brittle star. will these be compatable with a sandstar?
