Ultimate Octopus Aquariums Guide

Octopuses are absolutely fascinating creatures, exhibiting intriguing behavior and surprising intelligence. This guide will teach you everything you need to know to have your own octopus aquariums.


Why an Octopus?

An octopus is one of the most rewarding marine creatures you can keep in a home aquarium. We are fascinated by their behavior, ability to learn, and their stunning shape and color changing abilities. Notably, the unique personality each octopus has. If time and effort isn't an issue for you, on top of the relatively expensive diet, than an octopus might be right for you.

Some of the downsides of octopus-keeping include the short lifespan. In fact, most octopuses live for less than a year. Additionally, the cost of food can be quite high (mostly crabs and shrimp) and they have a tendency to hide or stay camouflage. Not to mention the very limited list of possible tank-mates. You most likely won't be able to keep your favorite coral or fish in the same octopus aquariums.

Despite some negatives, octopus aquariums and octopus-keeping can be quite easy in that they don't require much light, only need simple wet-dry filtration and don't demand the same precise conditions that reef invertebrates need.

The biggest challenge most octopus-keepers face is providing adequate food. Given that crabs and shrimp aren't cheap. Octopuses need live food for nutrition and enrichment, although most octopuses do accept some frozen food. You can often get away with frozen shrimp as long as it's supplemented with live crab. For this reason, octopus keepers that live long the coast have a great advantage as they can find food along the shore or buy from bait shops/ seafood stores.

Octopus Aquariums Requirements

Adequate size is an obvious necessity for octopus aquariums but there is far more than that to consider when preparing to care for your own octopus.  That being said, you're going to need lots of live rock (1:1 ratio for pound of rock to gallon of water), one-inch sand bed, wet-dry filter and sump, simple fluorescent light, protein skimmer and powerhead. No fancy and expensive equipment is necessary. No UV filter, no metal halides, no wavemakers or other devices.

Copper is deadly to octopuses so be sure that the aquariums you are planning to use has never been treated with copper. Also, the tank must be very cycled. This will take around 3 months if you are just starting. Water quality is incredibly important. Start with RO/DI water which is available at your local LFS.

FAQ's for Octopus Aquariums


Do Octopuses Really Only Live 1 Year?

Most of the time yes, and that is the sad part about octopus keeping. As pets most octopuses only last 1 year because they are already a few months old by the time they arrive.

Do Octopuses Bite?

Yes, Octopuses can bite. None of the common species you would keep are defensive biters. Octopus bites have been described as a bee sting sensation. Avoid placing your hand in any octopus aquariums if you have an open wound. It is quite easy to get an infection. Many pet octopuses never bite their owners. Nevertheless, please be careful.
