Sexing[edit | edit source]

Mature females are plumper than males, quite difficult to sex however.

Tank compatibility[edit | edit source]

Fire Eels are best kept with larger fish, that are not overly aggressive and likely to nip at the eel. They are nocturnal hunters, so smaller fish may be eaten.

Diet[edit | edit source]

This fish is primarily carnivorous and will willingly accept meaty foods including earthworms, bloodworms and other meaty treats.

Feeding regime[edit | edit source]

Once acclimatised will come out to eat once or twice a week, primarily nocturnal though.

Environment specifics[edit | edit source]

These fish must be provided with hiding places such as tubing and planting as well as a soft substrate.

Behaviour[edit | edit source]

These fish are generally peaceful in nature, however they are nocturnal predators and may take smaller fish.

Identification[edit | edit source]

A distinctive eel-like elongated fish with a long snout. The body is dark brown in colour with a paler underbelly, then with several red-orange lateral bands along the head and down part of the body. This pattern can vary between fish. Often the anal, pectoral, and dorsal fins have a red edging.
