In the wild they live in leaf litter and mud at the bottom of streams and rivers. This is the only place it is known but it is possible that it exists in other areas in the region. And even these still need to return to the sea to breed, so there are no truly freshwater species. We change water in the fishtank every 2-3 years.The tank is unheated.

It is not uncommon for them to swim to the surface to have a gulp of oxygen. Another thing these guys stand out with is their temperament. A fire eel does very well in community tanks as it mostly ignores fish that are not perceived as food. This fish is not to be kept in captivity unless you are a top-level specialist. Obviously, this is not the scary part. Click here to find out. The water quality should be kept in check as swamp eels are prone to fungal infections. Tire track eels will do fairly well (or even better) in slightly salt-ish water. We do not guarantee individual replies due to extremely high volume of correspondence. In the wild they will spend days like this, waiting for prey. (video), Tank of the Month, Another thing to consider about companions is that they should not be aggressive either. With the exception of oddballs like the hillstream loaches, most of the groups we refer to as loaches are vaguely eel-like in their shape.
