goodluck find any of those names in a LFS. almost all the LFS's have no idea what they have, how old it is, or how big it will get. most put common brown octopus, or just octopus alone. and if they lable it "dwarf" and its already a good size its either A.) not a dwarf and will grow pretty big or B.) is a dwarf but only has a short time left to live since most dwarfs dont live past 6 months to 1 yr anyways. GL though. you can prolly just dive for em and look for em under rocks.
