Polypterus Endlicheri Endlicheri

Datasheet

General Description

An incredibly hardy species, the Saddled Bichir (Polypterus Endlicheri Endlicheri) possesses very poor vision and relies heavily on its excellent sense of smell to locate food. Belonging to the category Polypteriformes, this fish is classified under the family Polypteridae. With a maximum size reaching up to 75.0cm, it is known for being a nocturnal creature that exhibits several interesting adaptations, such as a divided swim bladder serving as an accessory breathing organ.

Aquarium Setup

When setting up an aquarium for the Saddled Bichir, it is crucial to prioritize floor space over depth. The tank should have a soft substrate, driftwood pieces, and smooth rocks arranged strategically to create hiding spots. Although plants are not mandatory, a tight-fitting cover is necessary to prevent this adept escape artist from leaving the tank. For optimal conditions, maintain a water hardness of 5-25°dH, a pH range of 6.0-8.0, and a temperature between 22-27°C (see table).

Behaviour

Although relatively peaceful overall, the Saddled Bichir should not be housed with tankmates that it can fit in its mouth. Suitable companions include other Arowana, Synodontis, Datnoides, Knife Fish, large characins, and select cichlids. This species is known to be nocturnal and typically emerges from daytime refuges to hunt for invertebrates and small fish in shallow waters.

Feeding and Diet

Carnivorous by nature, the Saddled Bichir prefers live or frozen meaty foods such as prawns, earthworms, mussels, and lancefish. While some individuals may accept pelleted varieties, they usually do not take dried foods in aquarium settings. Ensuring a diet rich in these nutritious options is essential for their health and wellbeing.

Reproduction & Dimorphism

Reproduction of the Saddled Bichir has been achieved in captivity, usually by inducing spawning behavior through changes in water temperature and chemistry akin to the rainy season. This species is an egg scatterer, with the male fertilizing the eggs before dispersing them among vegetation. Notably, the male can be distinguished by a thicker anal fin compared to the female.

Habitat and Distribution

Widely distributed across various countries, including Cameroon, Nigeria, Burkina Faso, and Ghana, the Saddled Bichir inhabits rivers, marshy areas, and sometimes brackish environments like mangroves. Its natural habitat points to its adaptability to diverse aquatic conditions.
