I got my first octopus (a bimac) less than a week ago from MBG. We call him / her Leviathan (Levi for short). It is pretty small--smaller than a quarter, so I have not been able to get a good picture yet, but will post when I do.

Levi is active in day and is very interesting to watch. He readily takes small hermit crabs and snails, but is not too interested in shore shrimp. I'm a little concerned he is not eating much, because after feeding there is still a lot of carnage left over.

Octopuses are messy eaters. They will usually suck the meat out until they are full and throw the rest away. I wouldn't be concerned that the octopus doesn't eat the whole crab.

Hope he keeps doing good for you.

It is interesting to watch Sistrurus (7 month old Mercatoris, Caribbean pigmy) now that he will take a shrimp tail from me. He puts it under his mantle and then you can see him "sucking" out the meat. He gets taller and shorter and gives kind of a shutter. When he is finished he jettisons the shell still in one piece.
