I had given up hope finding another hummelincki for awhile and started to look at other options.
On Tuesday, I emailed Ken (Sealifeinc.net) to see if he could bring up a mantis shrimp since he was coming up for a conference (not MACNA) this weekend. I also mentioned I was looking for another hummelincki and tried describing it. Ken later replied that all octos look pretty much the same to him and he rarely paid much attention to them but if he came across something I could have it. It turned out that they were flying and not driving to Atlanta so the shrimp was a no go this weekend and their schedule was so packed that we would not even be able to get together for dinner.
Wednesday night I received an email that I was getting an unexpected FedEx shipment I concluded that he decided to ship the shrimp. Further down in my emails, I found a packing slip showing the shrimp AND an octo .
Serendipity is about the size of a large merc but she has all the markings (in miniature) of a hummelincki . I think she is female because she lacks the thickness that we saw in Octane (I also think females are smaller than males from guestimates of size on other posts), that could change, of course, but time will tell. I feel certain that she is quite young and am crossing my fingers that we make it through the next two weeks which seems to be the most critical timing for aquarium acclimation.
