Ropefish ( Erpetoichthys calabaricus )
The Ropefish, also known as the Reedfish or Snakefish, is a truly unique and ancient fish that brings an unparalleled level of interest and prehistoric charm to the aquarium. Despite its serpentine appearance, it is a peaceful and fascinating creature.
Max Size: Ropefish are substantial and long-lived, typically reaching 18 to 24 inches (45 to 60 centimeters) in length.
Behavior:
-
A peaceful and nocturnal species, though they can be active during the day once settled.
-
They are curious and inquisitive, often exploring their environment.
-
They are bottom-dwellers and will often rest on the substrate or among decorations.
-
Known for their ability to "walk" on their pectoral fins along the bottom.
-
Ropefish are gregarious and appreciate the company of their own kind; it's recommended to keep them in groups of three or more.
Tank Requirements:
-
Due to their length, a minimum tank size of 40 gallons for a single specimen, and 75 gallons or more for a group, is recommended to provide ample space.
-
The tank should be well-planted with plenty of hiding spots created by driftwood, rocks, and PVC pipes.
-
A tight-fitting and extremely secure lid is absolutely critical. Ropefish are legendary escape artists and can squeeze through the smallest gaps, often found dried out on the floor.
-
A soft, sandy or fine gravel substrate is ideal to protect their delicate skin and barbels.
Water Parameters:
-
Temperature: 72°F to 82°F (22°C to 28°C).
-
pH: Slightly acidic to neutral, generally ranging from 6.0 to 7.5.
-
Water Hardness: Soft to moderately hard water is suitable.
-
Excellent water quality with stable parameters is important. Regular water changes and good filtration are essential.
Diet:
-
Carnivorous, Ropefish are opportunistic feeders.
-
They readily accept a variety of live and frozen foods such as bloodworms, brine shrimp, mysis shrimp, earthworms, chopped market shrimp, and small pieces of fish.
-
They can often be trained to accept high-quality sinking pellets or sticks designed for carnivorous fish.
-
Feeding at dusk or after the lights are out can encourage shy eaters.
Compatibility:
-
Generally peaceful community fish that can be housed with other non-aggressive, similarly sized fish.
-
Avoid very small fish that could fit into their mouths, as they are opportunistic feeders.
-
Good tank mates include larger tetras, gouramis, peaceful cichlids (e.g., Kribensis), corydoras, and other medium-sized community fish.
-
Best kept in groups of 3 or more to encourage natural behavior and reduce shyness.
