Several years ago I cared for a pregnant octopus my son caught. Of course we didn't know she was pregnant at the time. However, she soon retired to a cave I had made for her and started stringing her eggs from the ceiling. She then began aerating them for what seemed like forever, but must have been several weeks. I can't rememeber how long. All that time she would not accept any kind of nourishment. I never peered into her cave and saw her when she wasn't aerating those eggs. I don't think she ever slept. I tried to find out what I should do when the eggs began to hatch, but in those days there was very little about the octopus in captivity. The smallest live food available were brine shrimp and I knew the babies would not eat those, at least that was my understanding. The female dies after the eggs hatch so there was nothing to be done for her, but I was hoping for some kind of a miracle for the progeny I guess. I don't know how many hatched, but I saw a few swimming around. Then, they just seemed to disappear and were gone. I really felt pretty rotten considering all the work she had put into giving them life and, through ignorance, I just let them die.
I would like to comment on statements I keep reading that maintain it is impossible keep an octopus unless you completely seal off the tank, for they will always try and escape. That is not strictly true. I have kept three octopusses on three separate occasions, not counting the pregnant female. None of these animals made any attempt at escaping although there was more than enough room to do so. Nor did any of them do any inking. I have reached the conclusion that as long as the animal feels safe and secure and is receiving enough food, it will, in most cases, stay put. And will ink only when it experiences real fear or terror.
I am now setting up a 20 gallon long tank for a baby octopus my son can capture at one of the spots where he goes fishing off his boat. I would like to communicate with people in a similiar situation so that we may compare notes.
Have a happy and productive new year.
