The Pacific Octopus, Octopus sp. are a dwarf species of octopus from the Philippines. It has a wonderful deep brown coloration. They are generally peaceful, and should not be housed with predatory fish that may harm them. They are best kept in tanks with plenty of live rock hiding places that are well-anchored to the substrate to avoid toppling. It is also very important to have a tightly sealed lid on your tank as the Octopus loves to try to escape - they can escape through the tiniest of openings. The Pacific Octopus eats a carnivorous diet of live Feeder Shrimp, Mussels, Crustacean Flesh, and small Feeder Fish. The Pacific Octopus has excellent eyesight, and will also scavenge at night. They grow to be approximately 14". They will readily eat frozen krill upon arrival and are generally very hardy. When feeding your Octopus, always be sure to approach the Octopus slowly and with caution, as to avoid causing it to release its ink cloud in defense. In the aquarium, this release of ink will cause the immediate need for a large water change to avoid its death, and the harm to it's tank mates. They will thrive in a temperature range of 72-78° F and a pH of 8.1-8.4. Acclimating can be difficult with the Pacific Octopus so this process is vitally important to the survival and health of the organism. The Pacific Octopus can be difficult to acclimate and care for, and should only be kept by an expert aquarist.
