In the ocean, these planktonic young float near the surface eating tiny organisms. When they get large enough, they sink to the bottom and find a place to hide. These have never been successfully raised outside a laboratory setting. Mine lasted about a week.
Right now, Aquamarine (O. briareus) has laied eggs. She is a large egged species, these I could try to raise. The hatchings are larger and benthic. It would be easier to find suitable food. However, if my calculations are correct, they will hatch while I am in Florida. My mother has a very aggressive form or brain cancer, we cannot put off this trip. My son will be looking after my tanks while I am away. He will have his hands full with daily tank maintenance, the dog and cat. (besides his job) The task of feeding baby octopuses would be challenging for me, just way too much for him. I am hoping that she laid later than I am guessing. (her den is near the bottom w/opening facing the back of the tank, unfortunately I cannot see in) If they hatch near the time of my return I just may be in luck. That being said, this is all contingent on the eggs being viable. I have not seen her in weeks. All I can do is keep my fingers crossed and hope for the best.
