i think your way off here spaceman, one year is the natural lifespan for most species of octo weather in the wild or a tank and they always die shortly after the eggs hatch more often she is killed and eaten trying to protect her eggs from preditors. in the wild most die much sooner since they are prey for almost everything in the ocean.whats more when octos die of old age(senescence) in the wild they slowly loose motor contrlole and eyesight and become paralyzed then they are slowly eaten alive by crabs, thats what I call a crule death, at least in a tank a responsible owner can put the octo out of it's misery in a humane way
the octos that I have kept lived happy well fed lives with nothing trying to eat them and even began to desire human contact, coming out to play a game of tag whenever hands come into the tank or dancing on the glass to get attention.
it's obvious you don't know much about them because if you did you would know that pe Mysis is to big and dead for babby cuttles and brine shrimp is useless because it has no nutritional value for them so maybe you should not be instructing others in their care. also these are tropical animals so keeping them in the summer is no different then keeping any other reef animal.
and if you going to preach about the cruelty of keeping animals to others the first thing you should do is go shut down YOUR tank!
