Thank you for your question. The Fox Face Lo is considered to be reef compatible with caution. Reef compatible with caution designates whether a species will cause harm to any coral, clam, crustacean or other sessile invertebrate in a reef aquarium. Some species of fish may be prone to consuming or harassing corals or invertebrates such as shrimp, anemones or feather dusters, but are otherwise wonderful reef fish cohabitating well with soft and stony corals. Such species are classified as Reef Compatible "With Caution." All reef aquariums are different in the organisms that they house, and a species that makes a wonderful centerpiece in one reef aquarium may cause havoc in another. Fox Face Lo are generally reef-safe if they are well fed. If not, they may nip at or consume some species of LPS and soft coral polyp. SPS Corals would be better suited for an aquarium with this type of fish. Here is a link to these corals: http://www.liveaquaria.com/product/aquarium-fish-supplies.cfm?c=597+322

Thank you for your question. If your aquarium parameters are testing at the appropriate levels, you do not need to add anything to your aquarium.
