I decided to journal Trapper's hatchlings on a new thread (see http://www.tonmo.com/community/index.php?threads/6959/ for the mother's journal and the hatchlings first 12 weeks). Another journal ends the experience with the last two surviving grandchildren. Recap summary: The Mercatoris hatchlings (does anyone know the proper name for octo babies and at what point I should call them juveniles?) began being born March 17th. Over a 5 day period, only six babies hatched. During the first week one died after climbing up the net about an inch above the waterline and apparently could not find its way back into the water. The remaining five are now approaching 13 weeks old (I changed the breeding net to one that is larger and has no netting out of the water). They rarely leave their current shell dens (but do change shells on occassion) and lie in wait for small shore shrimp and pipette fed Cyclop-eeze. Two of them will occassionally hunt the lower side of their partitioned net. In addition to the shrimp and Cyclop-eeze I have provided sailfin molly fry, snails, new hatch brine, pods and live mysis (brine, pods and mysis for the first 3 weeks only and in combination with Cyclop-eeze). The fry and snails are surviving very well on the Cyclop-eeze but the octopuses have no interest in the fish or snails as food. It is appears that they ate the brine, possibly the pods and always the Cyclop-eeze. So far, there has been no cannibalism but they are very well fed. I have recently twice found one shell firmly secured to another occupied shell but neither octopus seems to have damaged the other. I have also seen squabbles over the use of a particular shell. I keep the shells at least an inch apart and so far, everyone is alive. I plan to add a couple larger shells this week to try to avoid more arguing The net is open topped to the water but none have ventured out into the main tank. Since Mercatoris are nocturnal, it is difficult to photograph them and impossible without a flash. They do not appear to be concerned with the flash and remain visible after my attempts to capture them on film (well, electronic media).
