Mastacembelus Ellipsifer

Datasheet

General Description

Mastacembelus Ellipsifer, also known as the Tanganyikan Spiny Eel, is a striking eel species that serves as an intriguing addition to Tanganyikan community tanks. Belonging to the Mastacembelidae family, these eels are recognized for their hard dorsal rays, requiring careful handling to prevent injuries. Their complete lack of a swim bladder is an adaptation to their preference for bottom-dwelling lifestyles. African species like the Tanganyikan Spiny Eel feature conjoined dorsal, caudal, and anal fins, distinguishing them from their Asian counterparts.

Aquarium Setup

The tank setup for the Tanganyikan Spiny Eel involves creating sheltered areas using rock piles and ensuring a sand-covered tank base since these eels burrow in substrates extensively. It is advised to avoid gravel due to its potential to harm the eel's skin. Additionally, the aquarium should have no strong currents, and dim lighting is preferable as this species is predominantly nocturnal.

Behaviour

This species exhibits a peaceful demeanor towards tank mates that it cannot consume, making it unsuitable for most freshwater tanks due to its specific requirements for hard, alkaline water. In a Tanganyikan community setup, the Tanganyikan Spiny Eel can coexist with larger species, showcasing territorial behaviors towards conspecifics, necessitating a spacious tank for multiple individuals.

Feeding and Diet

In the wild, the Tanganyikan Spiny Eel feeds on small fish, but in aquariums, they readily accept various dead alternatives like prawn, cockle, mussel, earthworms, and bloodworms. Providing these food options ensures a balanced diet for this species in captivity.

Reproduction & Dimorphism

Reproduction of the Tanganyikan Spiny Eel has not been achieved in hobbyist settings, and their sexual dimorphism remains unknown, adding a layer of mystery to their lifecycle and breeding habits.

Habitat and Distribution

Endemic to Lake Tanganyika, the Mastacembelus Ellipsifer species is commonly found along the lake's shores, particularly in intermediate zones where rocky substrates transition to sandier bottoms. Their unique habitat preferences reflect their natural environment's characteristics.
