in my experience judging by the color mystic that is one angry or stressed occie
pale colouration is worried , camouflaged is you can't see me
after awhile and settled down they may put on a light show for you, red with white rings moving up and down the tentacles
an occie that is happy in its tank won't try climbing out, that is why it is best to get young individuals and grow them on
when really small they spend a lot of time hiding, i find a lot in beer bottles in the habour
they learn quickly and come for food
i used to tap my fingernails on the front of the tank to let one know it was food time
we were sitting in front of the tank having dinner a few months later
and i could hear a tapping noise coming from the tank
the occie was tapping 2 stones together to tell me to feed it
