With this theory about the Haitian supplied octos being affected by some unknown problem, I was wondering if there are any possible pathogens/viruses octopuses are susceptible to? My thinking is based on my experience with fish/vertebrates so it might be completely off-base, but I am worried about introducing another octopus to my tank. I know Vibrio and Brookynella can remain in a tank for some time after there are no more fish. Also, seahorses of different species can release pathogens into the water in order to eliminate competing species. What is the likelyhood of something similar happening with octopus? What makes autophagia "contagious"? I understand that if an octopus suffers from a condition that causes autophagia, the tank has to be sterilized or future inhabitants can share the same fate, which leads me to think perhaps this might not be the only thing that could linger in a tank and affect future octopuses housed in the same tank. Thoughts?
