My first octopus Julian passed away a few weeks ago, rest his hearts, but good news! He has been succeeded by my latest capture, Klaus the hawaiian day octopus! He is very active and seems to be adjusting well. He has about a three inch mantle length and is roughly 2 ft long from mantle to arm tip. I have been feeding him a diet of live crabs, crawfish, and raw shrimp when I have no live prey to offer. He has been eating very well and has quickly established a lair, which he is sitting outside of, eying me as I write this.
