High attrition for crabs and shrimp?

[Theulli]

Hello!

So my tank is extremely happy - corals growing like crazy, clam is opened up nicely (it's about 12 months old), no fish deaths, snails and hermit crabs all doing fine...

But I've had this weird attrition rate with my shrimp (fire shrimp and cleaner shrimp) and emerald crabs. I've had several die on me the last few weeks. Are there any params that those critters specifically would be more sensitive to?

Thanks!

Using RODI? Acclimation procedure? Stock list?

Do you acclimate them the same as the fish and corals? They tend to be some of the most sensitive inverts when it comes to acclimation and chemical changes.
