It's the Grand Mart in Centreville, at the corner of 28 and 29.
Was there again tonight and bought 2 of them this time. The shipment came in today and they had some pretty large ones, but the biggest one that had the thickest arms also had what looked like a gas embellism in its body, so I avoided that one. There were two of them that were together, one was sitting on top of the other and was sitting very upright and had nodules on its body that it was displaying and also had a nice pattern on it so I got that one but he grabbed the one below it, too, when fishing it out. The one started to crawl away so I decided to try it with two of them and see where that led me.
One absolutely HUGE difference I noted right off the bat, other than the display of texture on the skin, they inked in the bag... the other ones never inked at all, so they are obviously in better health to actually have ink left to give off. Anyway, since they inked, I put floated them in the tank and one immediately crawled out and the other one took some coaxing. I left the lights on in there and am cooling down an emerald crab to see what happens. The last ones lasted for days in the tank so I figure I'll acclimate this one down and then see if they eat it... the goldfish and the rosie were just to see if I could trigger a feeding response, I figure that if something is moving it might entice them to eat more than a crab that is sitting there trying to hide. The last one at least pushed away the fish when I put them on the end of a stick, so we'll see where the various foods end up as far as triggering feeding.
I did do some research on the seas around South Korea (I'm guessing they're not dealing with North Korean entities here!) and based on the latitude being similar to North Carolina/Southern Virginia I am basing water temps on that. During the winter months the water temp of the Atlantic goes down to around 50 so I unhooked the ice probe which will probably bring the temp up to around 56 or so. During the summer months the water temp of the Atlantic at that latitude, at least off the east coast of the US, goes up to around 77, so I will slowly bring that temp up if they do OK. I figure that the colder water will also reduce their need to eat as much so hopefully this gives them a chance to start eating. We'll see where this leads this time, but I think this will be the last time I try it if I'm unsuccessful. The price tag goes up each time I try it and it's hard to see them dead in there, although I may try it again if I can find out when they actually come in.
