Rope Fish

The Rope Fish, also known as the Reed Fish or Snake Fish, is one of the most unique and prehistoric-looking fish in the aquarium hobby. Native to West African rivers, these ancient fish have an elongated, snake-like body with a continuous dorsal fin that runs nearly the entire length of their body, giving them a rope-like appearance. They have modified lungs in addition to gills, allowing them to breathe air and survive in oxygen-poor waters. Rope Fish are primarily nocturnal hunters that use their excellent sense of smell to locate prey. Their small fins are used for crawling along the bottom rather than swimming, and they can even move on land for short periods. Despite their predatory nature, they are generally peaceful with fish too large to eat. Their unique appearance, primitive features, and interesting behaviors make them a fascinating addition to large aquariums for experienced keepers willing to provide appropriate care and tank mates.

Care Requirements

Tank Setup

Rope Fish require spacious tanks of 75 gallons or more due to their adult size. They need a soft substrate for crawling and numerous hiding spots with caves, driftwood, and PVC pipes. Ensure the tank has a very secure, tight-fitting lid with no gaps - they are excellent escape artists and can crawl out through surprisingly small openings. Dim lighting accommodates their nocturnal nature.

Water Quality

• Temperature: 72-82°F (22-28°C)
• pH: 6.5-7.5
• Water Hardness: Soft to moderate, 2-15 dGH
• Ammonia/Nitrite: 0 ppm
• Nitrate: <30 ppm

Feeding

These predators prefer meaty foods including bloodworms, shrimp, and small fish. They can be trained to accept pellets and frozen foods. Feed in the evening when they are most active. Use feeding tongs to offer food directly. They have poor eyesight but an excellent sense of smell for locating food.

Behavior & Compatibility

Rope Fish are generally peaceful but will eat any fish small enough to fit in their mouths. They can be kept with other large, peaceful fish or in groups with their own kind. They are nocturnal and secretive during the day, becoming active hunters at night. Their unique crawling locomotion is fascinating to watch.

Tips for Success

• Absolutely essential: secure lid with NO gaps; they are master escape artists
• Can breathe air; ensure they have access to the surface
• Primarily nocturnal; best viewed with moonlight or dim lighting
• Long-lived fish requiring long-term commitment; can live 15-20 years
• Soft substrate important for their crawling movement
• Poor eyesight but excellent sense of smell
• Can be kept in small groups if adequate hiding spots are provided
