Here is the US, Bandensis or dwarf cuttles are really the only ones readily available to the public, and they can be hard enough to find. there are many species of cuttles, but none that are native to our hemisphere, making there availability difficult. Most of the other species of cuttle are also much larger that the bandensis and they require a very large tank. You might be able to find Sepia officinalis, which is the 'the common cuttlefish' this is a larger species that requires a big tank (around 100 gallons per adult.)
