Harlequin shrimp in hiding!

[Lorna g]

I have a mated pair of harlequin shrimp, recently they are sitting in cave not coming out! Is it possible for this to occur after a molt? What can cause this to occur? They are well fed!

 

[Calappidae]

Harlequin only come out to hunt. It can take a few weeks for them to finish their prey. Once they are fed again they will drag their food to their over hang/cave/burrow and disappear for a few weeks. Whenever you see them hunting means it's feeding time again.

 

[Caronte]

agreed with Calappidae. They never go around until they're hungry
