Hi I am new here and really want to get a pet octopus. What do you all think the best pet octopus would be it has to be small though... I am wondering if you could answer a few questions for me. I want an octopus that is small tentacles no bigger than 5 inches and a kind of flashy, colorful octopus. I would love it not to be nocturnal, but whatever works. Thank you for your time.
