5ppm of nitrates isnt horrible....
for all we know it could be the way he was caught or stress from getting shipped or something (albeit a little late for him to stress so much now...) maybe he doesnt like the tank layout? i honestly dont know... IS it the 5ppm nitrates?
Keep doing water changes to bring down the nitrates. While it has been said that octopus can tolerate nitrates, it does actually stress the animal. Protein skimmers remove oils and proteins from the water that other filtration does not. At this point, I would still recommend a protein skimmer.
