I inherited some non-photosynthetic Gorgonians. They are decent sized ut im not really up for the requirements to keep these growing. Im honestly not sure how to tell how they are doing but i do see polyps frequently. The tank is fed marine snow, roti feast, and phyto with only blue light a few hours a day. Id love to trade them for a neon green nepthea or a couple sps frags. If not id do $40 for all 3 as a package deal.
