Fire Eel (Mastacembelus erythrotaenia)

Mastacembelus erythrotaenia

The Fire Eel (Mastacembelus erythrotaenia) is the largest and most visually dramatic member of the spiny eel family, reaching up to 100 cm in captivity. Native to slow-moving rivers and floodplains across Southeast Asia, it is prized for its striking red-orange lateral markings against a dark body. This comprehensive guide covers tank setup, water parameters, feeding strategies, breeding, health concerns, and compatibility — drawing on The Fish Collection's extensive experience importing and maintaining these impressive fish.

Electric Eel (Electrophorus electricus)

Electrophorus electricus

The Electric Eel (Electrophorus electricus) is not a true eel but a knifefish (order Gymnotiformes) and one of the most extraordinary freshwater organisms on Earth. Capable of generating electrical discharges exceeding 860 volts at 1 ampere — enough to incapacitate a horse — it has fascinated scientists since the 18th century. Recent taxonomic revision has split the genus into three species, but E. electricus sensu stricto remains the most commonly encountered in the aquarium trade. Keeping an Electric Eel is a serious undertaking that demands industrial-grade infrastructure, rigorous safety protocols, and legal compliance. This The Fish Collection guide provides the definitive roadmap for the rare aquarist prepared to house one of nature's most powerful living batteries.

Snowflake Moray Eel

Echidna nebulosa

The Snowflake Moray Eel (Echidna nebulosa) is widely regarded as the best "starter moray" for marine aquarists. Its manageable size (60–75 cm), relatively docile temperament, blunt crustacean-crushing teeth, and striking black-white-yellow patterning make it one of the most popular eel species in the marine hobby. Found across the Indo-Pacific on shallow reef flats and rocky intertidal zones, the Snowflake Moray is hardy, disease-resistant, and adapts readily to captive diets. This guide covers everything you need to know about keeping this charismatic eel.
