no, i don't see any attacks, as to the bodies, the tank has a bunch of atlantic serpent stars and 3 pistol shrimp in addition to lots of blue leg hermits.i have 3 tanks set up the same way with different corals so i know its not the crew. these tanks are all gulf aquaculture rock and sand. theres nothing else in the tank that could be causing this. the only other difference in this tank is a cleaner shrimp and thats not it.i,ve tried anthis, yw gobies, firefish and now the chromis. nothing lasts more than a week.i,ve had sw fish since the late 60's and never come across this.
