its still alive most likely.. thats what they do,, hang upside down in caves.. IMO there not good in tanks with lots of cracks and caves since you can really see them. I think I'd be able to see them in my tank since my rock is arranged in an open concept kinda way. Look how my serpant star is lol. I read that its better to keep them in groups and they only get about .5-1inch so how many do u think I'd eventually be able to keep? I was thinking 2 maybe 3, or two with a pom pom crab if I can ever get my hand son one.
