lobster and crabs only hide.

[Joshua Agostoni]

So i have two emerald crabs and one purple lobster i got them about 3 days ago.. I know that in the beginning there going to tend to hide until they are comfortable but i was wondering if anyone had and tips on getting them to be more active. I'm new to inverts other then snails, so any tips or tricks will help...

ps I dropped in mysis and one crab came out ate a piece and just went back to hiding.. i cant seem to find the other crab at all.

My emerald mostly comes out at night. I use a flashlight to try and find him. Of course this is in a six foot tank where he has alot more room to hide.
