The reason that I encourage you to find a suitable alternative live prey to feed your octopus is simple. In addition to taking only large prey items, they tend to be somewhat messy eaters, and water quality can be an issue if you do not have adequate filtration in place to keep up with the production of waste generated by an octopus. Inky, an enterprising octopus, squeezed out from his tank, slithered across the floor of the New Zealand National Aquarium, and down a pipe to freedom. So, if you can’t use feeders, what should you feed your octopus? For example, there are a plenty of good reasons that glass tops are not popular for reef tanks, including such issues as light Another potential for many people is live crayfish, which are seasonally abundant in many areas and often sold at bait shops for fishermen. As soon as that well-oxygenated water enters the aquarium, however, your animals and even the bacteria in your tank and filter begin to use the oxygen within it, and the more animals and bacteria there are in the tank, the faster that oxygen is used up. Tropical Fish Hobbyist #547: 94-99, Wood JB (1994) Don’t fear the raptor: an octopus in the home aquarium. Now we can come back to the issues of filtration and water quality. A clever and conniving octopus at the National Aquarium in New Zealand saw its chance for freedom and seized it — slithering out of its tank and disappearing days … even after I had glued them in place. BIZARRE footage shows a giant octopus making a desperate bid for freedom after escaping from its tank in a scene that looks straight out of hit film Finding Dory. The aquarium, near Dunedin, on New Zealand's South Island, was Sid's home for the past six months. He climbed out of his tank, stole the crayfish, replaced the lid on the crayfish tank, then returned to his own tank, shutting the door behind him. Staff would see one tentacle emerge from the tank, then another. Astro-Turf, which tends to discourage most octopuses from climbing across it. For example, I have seen some people have with great success with an undergravel filter and sealed glass top on an octopus tank, as well, but most octopuses tend to discover the undergravel plate makes a great cave, and promptly pull the filter apart to crawl beneath it. "He's a common octopus, so we're pretty confident he'll find a mate. try again, the name must be unique, Please First of all, the overflow must be covered in such a way that the octopus itself cannot get through the overflow and escape.

Aquarium Fish Magazine 5, Kraines S, Suzuki Y, Yamada K, Komiyama H (1996) Separating biological and physical changes in dissolved oxygen concentration in a coral reef. I think that they make a wonderful pet, and if their special needs are taken into consideration, they adapt well to aquarium life and can live out their entire natural lifespan in captivity. Even if you don’t mind having an octopus eat the majority of their tank mates, there are other problems you’ll face with trying to keep an octopus in a reef aquarium.

In the 2005 thread, “Octopus escapes from tank to prowl on its neighbors” poster Iustinus said he’d heard a story about an aquarium where fish kept disappearing from one particular tank. Although octopuses are invertebrates, and some species are certainly found on coral reefs, these animals are not particularly suitable for a reef aquarium for a wide variety of reasons that I will try to outline below. This leads to the odd situation in which the areas of lowest oxygen concentration on the reef are actually those with the most gas exchange, because in highly turbulent areas with extensive gas exchange, oxygen diffuses out of the water more rapidly and is closer to the saturation level of about 6.25mg/l. In fact, I have said more- or-less that same thing in this very article (above). 1992; Toonen 2000). The respiration of the animals in the aquarium would likely be on the order of ~ 2-3g of oxygen per hour. The shedding of skin is one of the primary reasons that I like to use a mechanical power filter of some sort on an octopus tank – most such filters on the market today will do a good job of removing and collecting all the floating skin from the tank quite quickly.

Animal Uprising: Octopus Attempts Escape At Seattle Aquarium (VIDEO) By Andres Jauregui. If you can succeed with that, you’ll likely have a happy and healthy pet that will repay the effort through their interactions with you. Technically, the proper pluralization of the “-us” ending for a Greek-root word such as octopus should be the suffix “-odes”, but octopodes is generally considered a bit of a mouthful, and in both the Oxford Dictionary and among the scientific community, the most common pluralization of octopus is simply “octopuses.” Even though this could be considered equally incorrect by purists, it is certainly preferable to the Latin pluralization of a Greek root in the obviously incorrect form “octopi.” So, I’ll get off my little soap-box now, but hopefully I have convinced you not to use “octopi” in the future.

The final common strategy, and the one that I tend to recommend to most people for a home aquarium, is to use a well-sealed tank (with the top held firmly in place using bungie cords, heavy weights or even duct tape) that overflows into an open sump which provides a simple way around the problems a sealed tank presents for gas exchange, protein-skimming and filtration. We offer a free open forum and reef related news and data to better educate aquarists and further our goals of sustainable reef management. This can be as simple as an air pump running a couple of airstones in the tank, or making sure that your air intake on your protein skimmer is plumbed in such a way that it draws from the room rather than inside your tank. The fact that an octopus, with the adorable name Inky, was able to escape its tank (and escape to the ocean by way of a laboratory drain) isn't surprising. I frequently see posts or hear people talking about “octopi” and it is somewhat of a pet-peeve of mine. Even the cnidarians (corals, anemones, hydroids and the like), which an octopus is unlikely to try to eat turn out to be problematic, but in the other direction this time – as I mentioned above, octopuses have extremely sensitive arms, and the constant stinging by the cnidarians is both a source of stress and potential infection for your octopus.
