CUC dieing, some advice please, newbie on board

[Zoaelite]

Agreed with Myka but to many people are supporting this 1 critter per gallon CUC rule and it's way over board.

IMO don't but hermits again they are not reef tank safe, now that your cycle is completed some blenny or goby and a few snails will work well for algae control.

I'm a little baffled about the crabs though as hermits are far from finicky. I was helping Colby @ elite clean out all of the old snail shells from his tanks and I missed 3-4 live hermits out of a whole pail, after rinsing with BOILING hot water a few times and letting it sit for 2 days I found live hermits chilling on the top.
