they are correct in what they say for most species of cuttle, sepia pharonis* (the cuttlefish that they have a DWA) do get very big and are realy hard to keep. however the dewarf species sepia bandensis comes from much warmer waters(indonesia, philippines) and is small enough that a single individual can be held in a tank as small as 20 gal. this is not to say that they are not time-consuming and high maintenence. My cuttlefish has to be fed live food daily (although some have had success on frozen) A Dewarf cuttlefish is reef safe( it will not harm coral, hard shelled inverts...) it will eat any fish its size or smaller, and all shrimp/crabs(not hermits). i plan to get more eggs around october/november so i should have babies then. i you would like i have some pics of them as babies that i can post
