Gold Fire Eel

This xanthic colour variant of Mastacembelus erythrotaenia represents one of the most extraordinary and coveted freshwater fish in the hobby. Rather than the typical jet-black body with vivid red lateral markings, this variant displays a brilliant golden-yellow to deep amber colouration across the entire body and fins, the result of a genetic reduction in dark pigment.

Extremely scarce — only a handful of specimens are known to enter the trade annually — each individual commands a very significant premium reflecting its rarity. Despite this exclusivity, its care requirements are identical to the standard fire eel: a very large aquarium with deep fine sand, excellent filtration, a completely sealed lid, and a long-term commitment of potentially two decades.

Earthworms are the food of choice. The golden colouration is best appreciated against a dark sandy substrate under warm white or amber lighting. This is a fish for experienced, dedicated keepers who can provide the infrastructure and long-term commitment that this extraordinary and irreplaceable specimen deserves.
