Missing richordea/mia

[Tony Buck]

I purchased an orange richordea where my LFS said to place under a net(like oranges come in) and let grow to rock for two weeks. About the third day I notcied the richordea was completely missing, what could have happened? I can't find it ANYWHERE in the tank and it was a good half dollar size. Do fish eat them maybe? I have a lawnmower blenny and some engineer gobies and damsels

I got one that ended up missing but it moved itself into a small crevice in a rock and it's been there ever since, maybe look between rocks and it small openings? I was only able to tell where mine was from the top of the tank looking down...hope it comes up!
