We will call it Pat, and if determined sex later we can say Patrick or Patrice. Octopus arrived today from Live Aquaria as "assorted Indo - Pacific octopus". As soon as I opened the cooler, the rank smell hit me. The water was 68' and very cloudy. There was also a small clam in the bag that was out of it's shell. 3 hr. drip acclimate, half way through I placed a 3/8" crab in the container. The octopus grabbed and killed it right away but discarded it within 1/2 hr. When released into the display it hung out on the sand for 10 minutes or so, then climbed up to the underside of a pseudo cave. Color changing occasionally and at times 1 or more arms hanging below it with the tips corkscrewed. I put 2 more very small crabs in there within sight, which it has ignored so far. Mantle is about 1.25" - 1.5". At least 1 arm is partially severed and another was severed some time ago as there is a new tip sprouting from the cut. I have no experience, but thought the arms seem pretty long - maybe 7" or 8", relative to body / mantle. The best pics so far are from in the acclimating container. One from in display shows 2 brown spots on a nearly dark mottled mantle. Any guesses yet?
