Any update as to the crinoid? Foods, etc? Got one the other day myself because someone else thought it would be easier.. lol (they soured their tank trying to feed so much)
At the moment I have some black sun corals I adopted and they're spawning regularly, have a few pop up around the tank.
Right now I feed Reef Energy, Nutricell, Reef Chili, and decapsulated brine shrimp eggs. It's only been in my tank a few days but he does close up during the day still. This is a good sign from what I've heard.
