Two months ago I lost the air conditioned in the house for a week. The tank
got way too hot and I lost a lot of stuff. I lost during the crash a
porcelain crab, decorator crab, anemone crab, 2 shrimp and 2 emerald crabs.
I have since replaced 4 different kinds of hermits, 3 kinds of snails, 3
anemones, some fish, cucumber, nudabranch, horseshoe crab and 2 emerald
crabs. Yesterday I found one emerald crab sitting pretty as you please on
top of my mushroom leather, dead, today I found the other one sitting on
some rocks, dead. Everything else seems ok as does that water parameters.
The skimmer is working just fine. The salt is a little low at 1.021.
Any Ideas on what could have killed the emerald crabs. In the past I have
had little luck with them also.

Thanks
