Easier just to go to KP Aquatics and scroll through the variety of gorgonians they sell. The description will tell you whether they are non-photosynthetic or photosynthetic. But I do like Purple Sea Feather, Yellow Sea Whip, Purple Plume Gorgonian, Spiny Orange Gorgonian, Knobby Sea Rod.What are some gorgonians that are photosynthetic?
