In my work at the National Aquarium in Baltimore, I've had the experience of working with a lot of really cool creatures. One such creature is our Giant Pacific Octopus. The personality and intelligence of these animals is just breathtaking. Ever since I first interacted with her, I've wanted to get one of my own. A few weeks ago, KP Aquatics got a few octopuses in stock, so I took the plunge and ordered one. I've named him Davy Jones. He's small, probably about a 2" mantle at the largest. He's been identified as O. hummelincki, but I can't find much information about these animals. I'm not sure how large he's going to get. I didn't know what specie I was going to receive when I placed my order, so I'm glad he's at least smaller for now. He's got a 40g breeder all to himself, and he has a ton of room to explore. Setup details: - 40g breeder - AI Sol Blue for light (set to 5%/10%/10%) - 16 lbs coarse/fine substrate - Lots of pounds of cured dry rock, not sure how much - 200w (I think?) heater - Jebao PP4 for flow - Air pump to help with aeration because of the tight-fitting lid. It's hard to get good pictures of him because he moves around pretty quickly and is a bit shy. Thankfully, he seems to be diurnal, so he's out during the day, camouflaged on the rocks. I'll share more as my journey with Davy progresses. The setup: Him in the corner to give you a relative idea of total size: Here's a good transition of him going from "camo" to "I'm annoyed you're so close and that you're taking my picture": This transition happened over the course of a few seconds, it was pretty remarkable.
