16. Please describe the emergency situation in detail.
This little guy just came up from a moly a few days ago. I was so excited to see him as it’s been 6 weeks at least and I was starting to worry. I saw him eating and going into the salt water dish 2 nights ago. See photo from that night attached.
I just moved stuff around in the tank trying to locate all the crabs since I noticed several empty shells in their cave and wanted to move them out to the rest of the shells. This little guy fell out of his shell when i moved him. His body seemed dry and stiff, but his legs moved limply when I lifted him (he didn’t move them). No motion on his part. I sprayed him with dechlorinated water and gently reshelled him and made an iso tank with fresh & salt water, honey, and bee pollen. Any hope? Anything else I can do??
