Can You Have an Octopus as a Pet? And Why Do They Always Seem to Be Plotting Something?

Octopuses are fascinating creatures that have captured the imagination of humans for centuries. With their eight arms, bulbous heads, and remarkable intelligence, they are often seen as mysterious and otherworldly. But can you actually have an octopus as a pet? And if so, what does it take to care for one? Let’s dive into the world of octopus ownership and explore the many facets of keeping these enigmatic creatures in your home.


The Allure of the Octopus

Octopuses are undeniably captivating. Their ability to change color and texture to blend into their surroundings, their problem-solving skills, and their curious nature make them one of the most intriguing animals in the ocean. For many, the idea of having an octopus as a pet is incredibly appealing. Imagine having a creature that can unscrew jar lids, solve puzzles, and even recognize its owner! However, the reality of octopus ownership is far more complex than it might seem.


The Challenges of Keeping an Octopus as a Pet

1. Complex Habitat Requirements

Octopuses are marine animals, which means they require a saltwater aquarium. This is no small feat. A proper octopus tank must mimic their natural environment, including:

  • Adequate Space: Octopuses need plenty of room to explore. A tank of at least 50 gallons is recommended, but larger species may require even more space.
  • Water Quality: Maintaining the correct salinity, temperature, and pH levels is crucial. Octopuses are sensitive to changes in water conditions, so regular monitoring and maintenance are essential.
  • Hiding Places: Octopuses are solitary and reclusive creatures. They need plenty of caves, rocks, and other structures to hide in and feel secure.

2. Dietary Needs

Octopuses are carnivorous and have specific dietary requirements. They typically eat live or frozen seafood, such as crabs, shrimp, and small fish. Feeding an octopus can be both expensive and time-consuming, as they require fresh, high-quality food to thrive.

3. Short Lifespan

One of the saddest aspects of keeping an octopus as a pet is their short lifespan. Most species live only 1-2 years, with some living up to 5 years at most. This means that forming a bond with your octopus will inevitably lead to heartbreak in a relatively short amount of time.

4. Escape Artists

Octopuses are notorious for their ability to escape from enclosures. Their soft, flexible bodies allow them to squeeze through incredibly small spaces, and their intelligence means they can figure out how to open tank lids or disassemble equipment. If you’re considering an octopus as a pet, you’ll need to invest in a secure, escape-proof tank.

5. Ethical Considerations

Octopuses are highly intelligent and sentient beings. Some argue that keeping them in captivity is unethical, as it restricts their natural behaviors and limits their freedom. Before deciding to keep an octopus as a pet, it’s important to consider whether you can provide an environment that truly meets their physical and psychological needs.


The Rewards of Octopus Ownership

Despite the challenges, there are some undeniable rewards to keeping an octopus as a pet. For those who are willing to put in the effort, the experience can be incredibly fulfilling.

1. Fascinating Behavior

Octopuses are endlessly entertaining to watch. Their curiosity, problem-solving abilities, and unique movements make them one of the most engaging pets you could have. Observing an octopus interact with its environment can provide hours of fascination.

2. Unique Bond

While octopuses are not social animals, they can form a bond with their owners. Some octopuses have been known to recognize their caretakers and even interact with them in playful ways. This unique relationship can be deeply rewarding for those who are patient and attentive.

3. Educational Value

Keeping an octopus as a pet can be a fantastic learning experience. It offers a firsthand look at marine biology and the complexities of caring for a highly intelligent creature. For families with children, it can be an excellent way to teach responsibility and foster an appreciation for marine life.


If you’re determined to keep an octopus as a pet, there are a few species that are more suitable for captivity than others. These include:

1. Common Octopus (Octopus vulgaris)

This species is one of the most commonly kept in home aquariums. They are relatively hardy and adaptable, making them a good choice for beginners.

2. Dwarf Octopus (Octopus mercatoris)

As the name suggests, dwarf octopuses are smaller in size, making them easier to house in a home aquarium. They are also less demanding in terms of space and diet.

3. California Two-Spot Octopus (Octopus bimaculoides)

This species is known for its striking blue rings and relatively docile nature. They are a popular choice for those looking to keep an octopus as a pet.


Setting Up an Octopus Tank

If you’ve decided to take the plunge and get an octopus, here’s a step-by-step guide to setting up the perfect tank:

1. Choose the Right Tank

Select a tank that is large enough for the species you plan to keep. Ensure it has a secure lid to prevent escapes.

2. Set Up the Filtration System

A high-quality filtration system is essential for maintaining water quality. Consider a protein skimmer to remove organic waste.

3. Add Substrate and Decor

Use a sandy or fine gravel substrate and add plenty of rocks, caves, and other structures for your octopus to explore and hide in.

4. Cycle the Tank

Before introducing your octopus, cycle the tank to establish a stable nitrogen cycle. This process can take several weeks.

5. Introduce Your Octopus

Once the tank is ready, carefully acclimate your octopus to its new environment. Monitor its behavior closely in the first few days to ensure it is adjusting well.
