I'm going to be setting up a 40g breeder primarily for mushroom anenomes and zoanthids. I would like to house a cuttle in the setup, however, my knowledge of cuttlefish is lacking. I've had experience caring for octopus; are care requirements for both of these cephalopods similar? Also, is the 40g going to be large enough. Any input would be appreciated. Also, what type of cuttlefish would do best in this type of setup?

Sounds like it would be good for S. bandensis, but its going to be hard to find one now as they are out of season. Browse around the forums for good background reading.
