The gorgonian should be in a low light area and low flow
Also ive notice that some corals just dont like T5 lighting ,since most of them are come from either natural sunlight or MH ,Ive notice the brains that i get dont like t5 lighting ,JMO
Need lots of food, phytoplankton, etc.. or else they will eventually starve to death Make sure they are not covered with algae preventing them to open. Good luck.
