A while back i saw a nautilus in a tank at my local fish store. I make a trip to the store every week and on the first week the guy at the store told me that he didnt think it was gonna make it...but to mine and his surprise week after week i came it was still alive. It was in a tank w/ seahorses, sea-apples and various corals. The guy let me hand feed it some frozen krill and it ate like no other! this shocked me...the water felt around 78F...How is this thing living???Has it adapted or sumthin?
