I received my first octopus from saltwaterfish.com Wednesday. I spent four hours dripping water from my aquarium into its travel water before I put it into the tank. My tank is a 75 gallon tank which has been set up as a refuguim for four months. There are no fish in there, just some crabs and snails. I figured the octpus would eat them. I also have about 40 lbs of live rock which is held together with putty from the LFS. All test on the tank have been great. I added bio-chem and phoso-ban about two weeks before the octopus was ordered to make sure there was nothing in the tank that would harm it. I disconnected the two aquariums and put a protein skimmer, canister filter and a power head in the octopus tank. Less than 6 hours after the octopus arrived, it was dead. Needless to say I was heartbroken. Any ideas on anything I could do to improve my chances on my next octopus? I don't want to get a pygmy but I don't want to get big one either. Any ideas where I could find another one? Also, are there any good books to purchase which will explain octopus care? I have read and read acticles from this site and others to gain knowledge but always on the lookout for new information.
