Can You Keep an Octopus as a Pet in the UK? Essential Care & Legal Guide

If you're considering a truly unique and exotic pet, an octopus stands out as one of the most fascinating choices. With their remarkable intelligence and intriguing behaviours, octopuses make captivating companions for those prepared for the specialised care they require.

The UK does allow ownership of octopuses as pets, but it’s essential to be aware of legal considerations, ethical responsibilities, and the specific care needs of these marine creatures. Unlike more common pets, caring for an octopus demands an understanding of marine aquarium setups and an ability to maintain a suitable environment.

This guide will explore the basics of keeping an octopus, focusing on tank requirements, feeding, interactions, and legalities to help potential owners make a responsible and informed decision.

Legal Considerations for Keeping an Octopus in the UK

In the UK, octopuses can be kept as pets without a specific licence, as they are not classified under the Dangerous Wild Animals Act. However, since they are exotic animals with particular needs, it is prudent to check local council regulations to ensure compliance with any additional rules or welfare standards.

Responsible ownership includes sourcing your octopus from reputable dealers or breeders who prioritise animal welfare and avoid supporting illegal wildlife trade. Always verify the origin of your octopus and ensure it’s suitable for captive care.

Housing Your Octopus: The Right Aquarium Setup

Octopuses require a carefully maintained marine aquarium dedicated solely to their needs. A regular saltwater tank for tropical fish or corals is not appropriate unless it’s set up exclusively for an octopus. They are known for being escape artists, so the tank needs a secure, tightly sealed lid to prevent them from wandering.

The environment should mimic their natural habitat, therefore:

• Tank Size: Typically, a minimum of 50 to 75 litres is required for smaller species, but size depends on the octopus species.
• Water Quality: Excellent filtration and frequent water changes are crucial because octopuses produce a significant amount of waste.
• Water Movement: Use pumps to maintain a steady flow of water, similar to tidal currents.
• Lighting: Low-level lighting is best since bright lights can stress octopuses.

Additional tank features like smooth rocks and hiding places help replicate their environment, giving them comfort and stimulation.

Feeding Your Octopus: What You Need to Know

Octopuses are obligate carnivores, requiring a diet primarily of animal protein. Live food such as shrimp, crabs, and small fish is often preferred, especially for wild-caught or less habituated octopuses.

While some captive-bred individuals may accept thawed frozen food, feeding can be challenging due to their individual preferences and dietary needs. Feeding time is also an excellent opportunity to build trust and interact with your pet octopus, who can recognise and respond to their caretaker.

Tank Mates: Should You Keep Other Animals with Your Octopus?

Generally, it is advised not to keep other animals with an octopus. They have strong predatory instincts and may eat tank mates like fish or crustaceans. Additionally, octopuses are antisocial and territorial, often intolerant to other octopuses and prone to aggression.

Some invertebrates may sometimes coexist depending on the species and tank setup, but this requires careful research and experience. For most hobbyists, a species-only tank is the safest and most humane choice.

Essential Care Tips and Safety Precautions

Octopuses are intelligent but delicate animals that can escape through surprisingly small gaps – any opening larger than the size of their eye can be a potential exit. Hence, ensuring a tightly sealed and escape-proof aquarium is vital.

Cover all intake and outflow pipes with mesh to prevent climbing, and avoid leaving unsecured gaps in or around the tank. Monitor water parameters daily and maintain consistent tank conditions to avoid undue stress on your octopus.

Remember, octopuses typically have a short lifespan, often around 12-18 months, and require committed care during this time.

Summary and Next Steps for Prospective Octopus Owners

Keeping an octopus in the UK is legal and possible, but it demands thorough research, commitment, and a suitable environment to meet their complex care requirements.

If you are ready for the challenge, start by ensuring your aquarium is fully prepared, learn about your specific octopus species, and seek advice from experienced marine keepers. Prioritise animal welfare, source your pet ethically, and be prepared for the unique responsibilities that come with owning one of the sea’s most extraordinary creatures.
