Octopuses, with their mesmerizing beauty and remarkable intelligence, often spark curiosity about keeping them as pets. Their ability to thrive in aquarium settings might lead one to believe they are low-maintenance companions. However, the reality of owning a pet octopus is far more complex and demanding than it initially appears. So, can you really have a pet octopus in the US, and more importantly, should you? Let’s dive into the fascinating yet challenging world of keeping these incredible creatures.
The Intriguing Intelligence of Pet Octopuses
Octopuses are celebrated for their exceptional intelligence and problem-solving skills. They are known to be curious explorers of their environments and can form interactive relationships with their caretakers. Denise Whatley from Georgia, an experienced octopus keeper who has cared for over 30 octopuses since 2006, has observed this firsthand. She trained her octopuses to associate hand gestures with attention and interaction. A video from 2011 showcases her eight-month-old octopus, Cassy, readily approaching her hand in the tank, demonstrating a clear recognition and learned behavior.

Whatley notes that some home-kept octopus species seem to enjoy gentle interaction, perhaps akin to a cat enjoying a scratch. She emphasizes that while it might not be affection in the human sense, they undeniably recognize individuals and behave differently around various people. Rose Blanco-Chamberland, another saltwater aquarium enthusiast, experienced this firsthand with her bimaculoides octopus, Cthulhu. She was astonished by Cthulhu’s intelligence, providing him with toys for enrichment. He particularly enjoyed chasing toys and showed a peculiar fondness for zip ties. Blanco-Chamberland also devised puzzle feeders using baby food jars filled with live food, challenging Cthulhu to figure out how to open them, providing both mental stimulation and entertainment.
Understanding the Demanding Care Requirements for a Pet Octopus
While the prospect of interacting with an intelligent octopus is alluring, potential owners must be fully aware of the significant commitment involved in meeting their specialized needs. These needs translate into considerable time, dedicated space, and financial investment. The aquarium setup and the ongoing provision of food are likely to be far more expensive than the octopus itself, which can range from $20 to $1,000 depending on the species and source. It’s crucial to note a critical safety warning: never consider purchasing a blue-ringed octopus. These are incredibly venomous, and their toxins are potentially fatal even from a seemingly minor exposure.
According to Whatley, a minimum of a 55-gallon aquarium is necessary, along with a secondary tank to house filtration equipment. Many experts recommend even larger tanks, with 70 gallons being considered a minimum for a softball-sized octopus. A long and low tank design is preferable, mimicking the octopus’s natural ocean floor habitat. Furthermore, a secure lid is absolutely essential, as octopuses are notorious escape artists, capable of squeezing through remarkably small openings.

Feeding an octopus presents another layer of complexity and expense. Typical pet stores do not stock octopus food. In their natural predatory behavior, octopuses hunt and consume anything smaller than themselves, while avoiding larger creatures. They require a diet of live prey, such as grass shrimp, crayfish, and fiddler crabs, necessitating a separate holding tank to maintain a live food supply. Blanco-Chamberland described keeping a dedicated tank in her bedroom to house live food for her octopus, typically feeding him two to three live creatures daily. While frozen krill was an option for emergencies, it wasn’t a favored food source.
The Significant Downsides of Keeping Octopuses as Pets
Even with optimal care, Katherine Harmon Courage, author of “Octopus! The Most Mysterious Creature In the Sea,” argues against keeping octopuses as pets. She highlights the ethical concerns, noting that breeding octopuses in captivity is challenging, resulting in most pet octopuses being wild-caught. This practice raises conservation concerns and questions the ethical implications of removing these intelligent creatures from their natural environment.
Courage emphasizes that octopuses are highly intelligent animals that are prone to boredom. A study she cites in Scientific American revealed that even octopuses in tanks enriched with flowerpots, stones, beads, and shells still exhibited signs of distress and self-harm. A standard fish tank setup is simply inadequate for their complex needs. Octopuses are not domesticated animals and are not naturally suited for captivity or companionship. Confining such intelligent, strategic, and playful animals for entertainment or novelty raises serious ethical questions about animal welfare.
Furthermore, an octopus in captivity might not be as actively engaging as one might expect. Many species are nocturnal, spending daylight hours hidden. They naturally spend considerable time in dens, and this behavior can intensify in the confined environment of a tank. This reduced activity outside their den could be a sign of stress and an indicator that captivity is detrimental to their well-being, suppressing their natural behaviors.
Whatley also points out the challenge of establishing a relationship with an octopus, as they are naturally shy. Some individuals may never adapt to a captive setting or human interaction. One octopus owner recounted his pet’s habit of squirting water across the room to gain attention, even occasionally inking the ceiling, leading to damage and loss of a security deposit. Unlike conventional pets like dogs or cats, octopuses cannot communicate their needs in ways humans readily understand. They require significant interaction and environmental enrichment, including interactive toys and stimulating habitats, demanding considerable dedication from their owners.
Octopuses are also highly sensitive to fluctuations in water parameters, particularly pH balance, requiring meticulous water quality management. Blanco-Chamberland emphasized that maintaining clean water was the biggest hurdle in octopus care. Their messy eating habits rapidly degrade water quality, necessitating frequent water changes and robust filtration systems to ensure their survival.
Finally, even with the most diligent care, the lifespan of a home aquarium octopus is typically short, often just a couple of years, and sometimes less for smaller species. This short lifespan means even the most devoted owner will have a limited time to bond with their pet.
Legality and Responsible Sourcing of Pet Octopuses in the US
While there are no federal laws in the US specifically prohibiting octopus ownership, regulations can vary by state and local jurisdictions. It’s crucial to research local laws and ordinances regarding exotic pet ownership before acquiring an octopus. Furthermore, ethical sourcing is paramount. Prospective owners should avoid purchasing wild-caught octopuses and instead seek out reputable breeders or suppliers who prioritize sustainable and ethical practices. Blanco-Chamberland strongly advises against purchasing from pet stores that may prioritize profit over animal welfare, potentially selling sick or dying octopuses.
Considering Alternatives to Octopus Pet Ownership
Given the significant challenges and ethical considerations associated with keeping octopuses as pets, exploring alternative ways to appreciate these animals is advisable. Visiting public aquariums offers a fantastic opportunity to observe octopuses in professionally managed environments that are designed to meet their complex needs. Appreciating octopuses in their natural ocean habitats, through responsible diving or snorkeling, is another enriching and ethical option. For those fascinated by marine life, even virtual aquariums or educational documentaries can provide a fulfilling way to learn about and admire octopuses without contributing to the demand for them as pets.
Conclusion: Rethinking Octopus Ownership
While the intelligence and unique nature of octopuses make them incredibly captivating, the realities of keeping them as pets in the US are fraught with challenges. Their demanding care requirements, ethical sourcing concerns, short lifespans, and the potential for distress in captivity strongly suggest that they are not suitable pets for the average person. Before considering octopus ownership, it’s essential to weigh the significant commitment involved and to consider whether providing a truly enriching life for these complex creatures in a home aquarium is realistically achievable and ethically justifiable. Perhaps, our admiration for octopuses is best expressed through conservation efforts and appreciating them in their natural world, rather than in a home tank.
