Having kept Sepia officinalis (cuttlefish) several times, one problem is that they grow relatively large, and if they are hatched from eggs there may be several! I was wondering if any other species would adapt to aquarium life (e.g. smaller Sepia or even some of the more sedentary squid?). Would there be a source for these - perhaps eggs would travel round the globe better than animals? I anticipate that feeding the young will need more preparation for small species.
