Hiding in his shell. Every now and again, he pokes out a little, but he's prolly really scared at the moment, being a soft "shell" and all.
I really freaked at first 'cuz I have him and the bumblebee in the same acclimation container, and suddenly the bee was munching on the leftovers. I was all, what? are bumblebees really nasty and no-one mentioned it on the sites I researched?
2 hours down, prolly another 1/2 hour or so to go. Salinity almost matches now. The inverts I ordered came in at 1.027, and the fish at 1.020. I run @ 1.025. One coming up, one going down...
