Cuttlefishes

These 'invertebrates' are included in this section, even thought they are part of the Mollusk family because they are of general interest to some fish-only aquarists. They belong in the Cephalopoda family, as does the octopus, squid, and chambered nautilus. They appear to be highly intelligent, as are octopuses, and can also change their color and texture such as the octopus. They come from a wide range of areas and whatever species selected; you'll need to know its area of origin so as to know its water temperature requirements.

Like squids, they have ten arms, and eat other fish and crustacean. They can consume large amounts of food and should be housed in large aquariums with a highly oxygenated water supply. Those interested in obtaining captive breed cuttlefish can contact the National Resource Center for Cephalopods.
