Tire Track Eel (Spiny Eel) – LiveAquaria
The Tire Track Eel, also known as the Spiny Eel, is a nocturnal predator belonging to the Mastacembelidae family. This fish is not a true eel but an elongated tropical freshwater species with multiple spines before the dorsal fin.
It is a carnivorous species that digs in the substrate and may bury itself, potentially uprooting plants or disturbing decorations. A larger aquarium with a soft substrate is recommended to accommodate this behavior.
Two teaspoons of salt per 2.5 gallons of water is suggested for water stability. The eel should be housed with large, non-prey fish that it will not view as food.
Breeding habits of the Tire Track Eel have not been documented.

The eel is active at night and enjoys digging in the sand. I have a 55-gallon tank with soft sand, and it’s not disturbing my plants as much as I feared. Feeding it frozen bloodworms works well. Just make sure to keep it with larger fish.

Great addition to my tank. It’s quiet during the day and becomes very active at night. The digging behavior is noticeable but manageable. I added salt as recommended and the water stability has improved.

It’s a bit of a hassle to maintain because it digs and moves things around. I had to rearrange some plants. Feeding is straightforward, but it’s not for beginners due to the active behavior.
