Hi, I'm new to the forum 
So 3 months ago i finished cycling my old 40gallon reef tank that i used for only 2 clownfish fowlr tank back in 2015. I left it unused with water still inside and evaporates leaving only half the volume of the tank at the end of november 2017 due to the mysterious deaths of my 2 clownfishes.
The liverock used to have a mantis shrimp that hitchhiked on it, but i managed to caught it way before, like a year before the mysterious death of my clownfish.
I reused the liverock that had been left for like 6 months in the tank with half the volume of water due to evaporation and pumps off. I rinsed the live rock with RO water and found a remain of a big furry (probably xanthid) crab. I thought that the liverock should be pest free already.
Now my tank is filled with 2 clownfishes, 2 banggai cardinalfish, 3 cleaner shrimps, and some lps corals.
This evening i was checking out if everything in the tank is just fine, then i heard a clicking noise. Could it be that somehow a mantis shrimp hitchhiked on the liverock? How could it survived such harsh condition with water evaporation, high salinity, absence of food, and freshwater rinse?
Thanks before
