Ok, well I just might set the record for negative replies on this thread.... Here goes, New to Ceph care and know nothing other than what I've browsed here. I have a new but 3month established 120g tank. The plan has always been to build a really awesome octopus tank....good so far? I live in palm beach county, FL and have access to quite a few reef specialty stores. Of which, all have struggled since July 15 or so to find me the octopus I'be so coveted.(nothing special, I was told a common octopus would be a better fit than a Pygmy. No store's distibutors had any at all) I heard about a new store opening from a friend, and guess what? They had one in stock!($40, owner said he'd had it since July 9) After bringing it home 2 days ago it has bewildered and amazed my entire household. (Feeding from my hand, playing with Legos and glass jars) Love it. Still with me? Here's the problem, we've been so obsessed with playing with it, and taking pictures/videos, today I counted its arms. 7! What do I do? Google says its capable of 11ft and 165lbs. Is it cruel to keep? Will its size/life expectancy change drastically due to the 120g tank? Will it lift lids with just a few lbs weighting them down? Obviously I'm to blame, reef store owner too (but he looked to be 20-25 yrs old and attempting his first try at a real business) I'm an idiot one way or the other, but am I one for not knowing the species before I buy, or one because maybe I'm missing something and this isn't actually Haliphon Atlanticus?
