The Tyre Track Eel (scientific name: Mastacembelus armatus) is a fascinating and popular species among aquarium enthusiasts.
Named for the tire track-like patterns on its body, these patterns vary between individuals, making each eel unique.
Typically brown to olive-green in color with lighter underbellies.
They have elongated, snake-like bodies with a pointed snout.
In captivity, they can grow up to 20 inches (50 cm), but in the wild, they might reach lengths of 30 inches (75 cm).
They require a large aquarium due to their size.
Native to rivers, streams, and floodplains of South and Southeast Asia.
They thrive in warm, slow-moving waters with plenty of hiding spots.
Tank Size: Minimum of 125 gallons is recommended for adults.
Water Parameters:
Temperature: 75-82°F (24-28°C)
pH: 6.5-7.5
Soft to moderately hard water
Substrate: Fine sand or smooth gravel to prevent injury to their delicate bodies.

Tyre Track Eels are mostly nocturnal and shy, especially when first introduced.
They are escape artists and require a tightly sealed aquarium lid.
Though not aggressive, they can eat smaller tankmates, so choose companions carefully.
They are carnivorous and thrive on a diet of live or frozen foods like bloodworms, brine shrimp, and earthworms.
Over time, they may accept high-quality sinking pellets or tablets.
With proper care, they can live 8-18 years in captivity.
Best kept with larger, peaceful fish that won’t outcompete them for food.
Avoid overly aggressive or very small tankmates.
