im thrown off by the little arms its got. It definitely looks fleshy but the shape definitely reminded me of a pectiniaIt's not a mushroom, duncan or any other LPS or SPS coral. If it's a pectinia it's the most sickly example I've ever seen. Sticking with leather (not a toadstool).
it doesn’t open up any. It just expands with the light on and shrinks when they’re off.
I’m going to vote it’s a Sinularia polydactyla. A better photo will help but it really reminds me of this species of Sinularia.Does anyone know what this coral is called? I’d like to do research on caring for it. It seems to be maintaining but I feel like it could do better if I knew how to handle it. Thanks for your help.
