hi guys are cuttles more sensitive or harder to take care of than octos? i have a bimac since last june w/no problems. i was thinking of getting a cuttle but was wondering are they less hardy than octos? i have a 300 gal so i would like to buy a larger type other than whats available like what thales have. or would that be good for that kind of cuttle? and do they have to be kept in pairs or would just one in the 300 be okay? thanks everyone jimmy.
