The Fire Eel is a nocturnal predator, and part of the Mastacembelidae family, also referred to as the Spiny Eel family. Members of this family are not true eels. They are elongated, tropical, freshwater fish that have numerous spines preceding the dorsal fin.
Best suited for a larger aquarium, a soft substrate is necessary for this fish. The Fire Eel will often dig in the substrate and bury itself; this may uproot plants and rearrange decorations. A tight lid should be used for any long, slender fish, as they will often try to escape from the aquarium. The Fire Eel should be kept with fish of similar size or larger, and will not tolerate its own kind.
Unfortunately, the breeding habits of the Fire Eel have not been documented.
