Ordered an O. vulgaris in yesterday from the Florida Keys as I have been looking for my next octopus adventure and wanted something bigger that would also live longer (I have to admit I also wanted to be able to buy blue crabs at the market as food as that would be a neat way to watch feeding behaviors). While not necessarily unhappy I am a little disappointed that I received a very small octopus which I think may actually an O. briareus. While this species does get to be a good size it is not as big as what I was looking for. Fortunately it is very small right now, resting position is showing a mantle about 2-3" across, so I know it is young and hopefully I will have lots of time with it. This one inked in the bag after unpacking the box so it was speed acclimated (aka moved immediately to new water without any acclimation) and spent the day in a bucket with a chunk of rock until I got it home. Tossed in a few emerald crabs in case it got hungry but it didn't show any interest but I can't blame it for that. I floated it in the tank and poked a few holes to allow it to acclimate and crawl out when it wanted to as I had to go to soccer practice and when I got back a couple of hours later it was still in the bag. No signs of distress or anything concerning so I released it into the tank and it went into hiding but fortunately where I could observe it. ID is not certain so if you think I actually have a different species please chime in. I know for certain it was collected in the Keys and that seems to narrow it down but the general appearance of these two species seems to be similar enough to allow for confusion. Color does appear to be more of a greenish-brown but it has been mostly pale or an angry dark color so far only, no real calm colors yet.
