Brittle Starfish hiding

I purchased a brittle a month ago and havent seem him since the day he went into the tank and into a hole in the liverock. is this a normal thing for anyone who has them?

thought mine was a gonner after I didnt see it for 3-4 weeks then one morning he was climbing the glass :BEER

Yes that’s normal - more often than not you’ll only see a tentacle sticking out from a crevice.

Ok. Well I’m hoping to hats the case. Last thing I need is a dead starfish inside of a rock
