Polypterus

The size options describe the supplied fish. Compare the named species’ adult dimensions, aquarium footprint and filtration plan before choosing a juvenile. Senegal, Delhezi, Saddled, Lapradei, Ornate and Teugelsi offers need their own assessment; an albino colour form does not remove the adult-space requirements. Check exact identity and supplied grade when comparing similar-looking young fish.

Bichirs need access to atmospheric air as well as a filtered aquarium. Leave a clear route to the surface and secure the lid and service openings. Plan feeding and shelter around the complete stocking list: small fish that can be swallowed are unsuitable companions. Check what the selected bichir currently eats, and watch that it can feed without being outcompeted or harassed.
