Gosh, I had such good intentions when I first found TONMO... funny how a busy office and an 18-month-old can really muck up your intentions. Anyway, I'm a ceph fan, at least from books. Spent some time this year reading some ceph-specific and ceph-related books. Keeping one as a pet is an interesting idea but I don't think something I have time for now. I can say, though, that I was at the DC National Aquarium this year (not the on in baltimore) and to my surprise, small as it was, they had about half a dozen nautiluses! We took a few pictures but the tank was dark so the pictures were too. But they were pretty cool.
