anyone out there got some decent sized ones? i read on here that they do well in full fresh so i plan to get a few since they get decent sized. my lfs has a ton and i've never really seen them available. before. they look real cool. anyone else got some in full fresh?? how long can they survive in full fresh? and whats there availability in other areas? some say there "rare" or hardly available. but my lfs has like over 30.
