Tonight Jess and I noticed about 10 tiny planktonic baby octopuses swarming by the top of the tank. 4 hours later there has to be several hundred. So Gimpy was in fact fertile when I bought her from the LFS 4 months ago. She denned 5 weeks ago and the eggs have hatched tonight. She is no longer as holed up now that her babies have hatched. Sad part is they are just about impossible to rear. Amazing part is that she was quite young when caught, and now I'm wondering if the fact she was missing an arm was from an encounter with a male octopus in the wild.
