Ambient - she's on a flow-through system and is at a combination of the air temp and whatever the oustide water temp is (after it's been through the pre-filter). So at the moment about 22; in the winter it drops to about 16 I think?
Just had to share a Mud update. She has grown a bit, though not as much as the other little octo we picked up at the same time, who was about a quarter of her size and is now easily equal. Still likes to come up and play, and the other day she apparently got one of the other staff members into a sticky spot - he wasn't paying attention while feeding her, and somehow she managed to get such a hold on his arm that he was stuck facing away from the tank with his arm basically pinned behind his back! (I'm a little skeptical on this - her mantle is slightly larger than a large grapefruit and her arms are probably about a meter long, but she's never put me in a hold I couldn't easily break.) But wait, the story gets better - at this point Mud began to bite. She gave the guy a small nip on the hand, then moved to a different spot and really began to chew, which he somehow tolerated for a half hour (he maintains he was stuck) until someone from the public distracted her and rescued him, finally permitting him to withdraw his bleeding hand from the tank! And within minutes, the site of the second bite had swollen to about twice its original size, which as far as Steve can recall is the first incidence of anyone ever being envenomated by Pinnoctopus cordiformis. (I mean - who stands around long enough to get envenomated??)
We've held them for 74 years and have no records like that!!!!! But it was a MALE keeper right (sorry guys!) Maybe he wanted to feel things from a crabs perspective???? One of our blokes decided to see how the stings of a sea anemone felt on his lips...............................!
