Rope Fish

The Rope Fish, also known as the Reedfish or Snakefish, is a captivating freshwater species originating from the swamps and slow-moving rivers of West Africa. With its elongated, serpentine body and distinctive dorsal finlets, it brings an ancient, prehistoric charm to a home aquarium. These medium-sized fish are known for their impressive lifespan, often living between 15 to 18 years with proper care. They are peaceful, bottom-dwelling predators that thrive in well-planted tanks with plenty of hiding spots. In New Zealand, the Rope Fish is generally legal to keep, offering Kiwi aquarists a unique and long-term aquatic companion, provided they confirm current MPI and local council guidelines.

Estimated annual vet/care costs for a Rope Fish are relatively low, typically NZD $50 - $150. This primarily covers quality food, water conditioners, filter media, and potential medication for common ailments. However, access to exotic fish veterinarians in New Zealand is limited. While general vets may offer some assistance, specialist care for complex fish health issues can be scarce and potentially expensive if a specialist consultation is required. Prevention through excellent water quality and appropriate diet is key to minimising vet needs.

NZ Lifestyle Fit

Rope Fish are well-suited for various New Zealand home types, from apartments to larger houses, provided a sufficiently sized aquarium (120L minimum) can be accommodated. Their quiet nature and minimal space requirements outside of their tank make them ideal for urban living. Climate considerations are important for their tank environment; while Auckland's humidity or the South Island's colder temperatures won't directly affect an indoor, heated aquarium, stable water temperature (24-28°C) is crucial. Ensure your heating system is reliable, especially during colder months. There are no specific regional restrictions on keeping Rope Fish within New Zealand, as their legal status is generally permissible nationwide. However, always double-check with MPI and your local council. Legally sourcing Rope Fish in NZ is typically done through reputable pet stores specialising in aquatic life or through established local breeders. Avoid any unregulated or black-market sources to ensure the health of the fish and compliance with NZ biosecurity laws.

About This Fish

The Rope Fish (Erpetoichthys calabaricus) is a truly unique and ancient species, often considered a 'living fossil' due to its primitive characteristics. Hailing from the freshwater environments of West Africa, particularly in countries like Nigeria, Cameroon, and Congo, these fascinating fish are known for their eel-like bodies and a series of small, individual dorsal finlets rather than a single continuous fin. They are not true eels but belong to the Polypteridae family, related to bichirs. Rope Fish are nocturnal and crepuscular, meaning they are most active during dawn, dusk, and nighttime, exploring their environment for food. With a potential lifespan of 15 to 18 years, they represent a significant long-term commitment for any aquarist. Their calm demeanour and intriguing appearance make them a popular choice for experienced freshwater enthusiasts looking for something out of the ordinary.

What They Look Like

Distinguished by their long, slender, snake-like bodies, Rope Fish can grow to an impressive length of up to 50-60 centimetres in a suitable aquarium environment, though they are often smaller in captivity. Their colouration typically ranges from olive green to brown on the dorsal side, fading to a lighter yellow or cream on their belly, often with a subtle marbled pattern. They possess small, pectoral fins that resemble paddles and a series of 8-15 small, individual dorsal finlets along their back, which are a hallmark of their species. Their eyes are relatively small, and they have a unique, almost cartilaginous skeletal structure. These fish also have a pair of functional lungs, allowing them to breathe atmospheric air, which is a key adaptation for their natural habitat where water quality can fluctuate.

Personality & Behaviour

Rope Fish are generally peaceful and shy, preferring to spend their days hidden amongst plants, driftwood, or rockwork. They are primarily bottom-dwellers and will often be seen resting on the substrate or slowly gliding through the lower levels of the tank. Despite their predatory nature, they are not aggressive towards tank mates that are too large to be considered food. They are social animals and thrive best when kept in groups of three or more, which encourages more active and confident behaviour. When kept alone, they can become withdrawn and stressed. Their nocturnal habits mean they are most active after the lights go out, diligently searching for food with their keen sense of smell. They are known for their ability to squeeze through incredibly small gaps, so a secure, tightly fitting lid is absolutely essential for their enclosure.

Life in New Zealand

For Kiwi aquarists, the Rope Fish offers a unique addition to a freshwater setup. Its legal status in New Zealand is generally permissible, meaning it's not a prohibited species under the Biosecurity Act. However, prospective owners must always adhere to the mandatory legal instruction: this animal is generally legal in NZ, but owners should still check current MPI (Ministry for Primary Industries) guidance and local council rules before acquiring one. Sourcing should always be from reputable, legal pet stores or breeders within New Zealand to ensure compliance and the health of the fish. Given their preference for stable tropical conditions, they are well-suited to indoor aquariums across New Zealand, from the humid Northland to cooler South Island regions, provided the tank's heating and filtration are robust.

Is This the Right Pet for You?

Bringing a Rope Fish into your home is a rewarding experience, but it requires a commitment to providing a specific environment. Their long lifespan means you'll be caring for them for many years, so consider the long-term dedication. They need a spacious aquarium (120L minimum for a small group) with excellent filtration and plenty of hiding spots. Their social nature means they thrive in groups, which means more space and resources are needed. While generally peaceful, their predatory instincts mean careful consideration of tank mates is crucial. If you're an experienced aquarist looking for an intriguing, low-maintenance (once established) fish with a unique personality and are prepared to provide a secure, species-appropriate habitat, then the Rope Fish could be an excellent addition to your Kiwi home.
