The day octopus is, unsurprisingly, more active during the day. Note the manybar goatfish in some pictures; they often hang around octopus, and are a good way to find them before you're so close the octopus hides under a rock.

They can change color and texture very quickly. These shots were taken just a few seconds apart:
