why would anyone even buy something they KNOW is going to die, and even if not die within a week or two, very soon after, yes maybe a very small hand full of people have had luck with keeping them in a tank, at least 90% dont. if you ask me, i think its very mean to keep something you know is going to die just so you can watch it for the times its alive, im all for keeping them in the sea, and if you want to see one, turn the tv on or go diving, just my 2 cents.
