Yesterday morning I woke up to a dead tiny rugosus. Shell in the water dish and body next to it. So frustrating to have a random death. This crab was one of the last orders I was owed from an online seller. They were shipped unexpectedly in November 2016 to repay money I was owed for another species that I never received. (Note: ordering online is not reliable, you will get ripped off. If not the first order, soon thereafter.) So they were shipped while it was too cold and while I was not prepared to receive them and properly introduce them. This makes two out of the group that have died, which overall is pretty good odds. Still sucks 🙁
