Hi everybody, can anyone please help?! I bought a red starfish today, with black tips, I acclimatised it properly and didnt expose it to out of water, he has been at the bottom of the tank all day(14 hours and has moved very slightly) it has tiny tentacles sticking out, I don't know whether it still alive, do they take a while before they start moving around or is it more than likely dead or dying? Thank you in advance.
