Welcome to TONMO, the premier cephalopod interest community, and birthplace of #WorldOctopusDay and #CephalopodAwarenessDays. Founded in 2000, we are a large community of experts, hobbyists and enthusiasts, some of whom come together when we host our biennial conference. To join in on the fun, sign up. You can also become a Supporter for just $50/year to remove all ads and enjoy other perks. Follow us on Twitter for more cephy goodness.
We recommend keeping most octopuses in their own private tanks to prevent cannibalism. Your best bet will be to attempt to find video/images of animals in the wild that divers have been lucky to view. Our Diving and Ceph Encounters forum may be somewhat helpful.
