Octopus, Squid and Cuttlefish keeping

In general I am curious if any of you have kept any of the three mentioned in the title.

I've seen Octopus and cuttlefish kept as pets, but never squid. Has anyone ever kept squid? is it possible?



But im mostly interested in Octopus and Cuttlefish. Both seem interesting and I just wanna know about keeping them for curiosity sake. So have any of you kept them? Any stores? Words of Wisdom?
