Tyre Track Eel - 6-7cm

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.

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.
