Are for the very advance hobbyist. Keeping one for a 100 days is hardly a success. And yes they need a vertical tank at least 150 gal for one speciman. They also need a chiller and they must remain in the dark, otherwise they will go blind ( not that they can only see in the dark ). The Nautilus are slowly becoming endangered and to take them from the deep oceans so someone can have a trophy pet is an impulse buy at the expense of the Nautilus. I imagine most have what you stated is hear say. Please provide valid scientifc information and pics, before you suggest that anyone can keep a Nautilus. L 8 2 Rise

I did, however, say that the thread is getting out of hand and no, they don't need thousand gallon tanks and zoos, etc.If you are dedicated and do your homework, you can do it, however I wouldn't because, as stated, they're boring, hard to keep, etc.
A Nautilus is not a sps or a lps. While some filefish are now being kept with success most perish in the home aquarium. The point is this particular item is almost endangered, so you are encouraging people to go for it. I hope people of the future will be able to see them in the wild other than public aquariums. There is an extensive list of animals both marine and land animals that can no longer be seen in the wild. They are kept in zoos where they have very limited chances of breeding successfully. Why not just take what we want from the oceans and see if they survive in the average home aquarium. Lets start with leafy sea dragons. I have been diving all over the world and the population of wild sea horses is dismal at best, but lets just keep harvesting them.
It does look like Naut populations are declining - at least locally. In places where they used to be collected easily, they are no longer collected easily.
IMO, Nauts are not an animal that should be tried on a lark or whim. They have specialized needs and are not the most interesting animals most of the time, so you really need to be interested in them in particular if you want to keep them. I wish LFS would only special order them instead of trying to stock them for impulse buys.
There is plenty of misinformation out there regarding nauts, both about how hard they are to keep and how easy they are to keep. Please before thinking about Nauts (or any ceph) do some real research. TONMO.com is a good place to start, as is the TFH cephalopod issue from a year or two ago, and Cephalopods: Octopuses and Cuttlefish for the Home Aquarium ( http://www.amazon.com/Cephalopods-Octopuses-Cuttlefish-Home-Aquarium/dp/0793806585 )
http://www.newscientist.com/article/mg19826501.700-nautilus-chambers-of-secrets.html?full=trueIts funny for some one to ask for facts to back up claims- then make up facts themselves! Pretty close to endangered animals are protected species- all others are fair game for the trinket trade- live or otherwise. Not that I agree or would keeep them.
