Banded Bichir - Polypterus delhezi - Small

The Banded Bichir (Polypterus delhezi) is a long, slender fish that has a prehistoric appearance. The body is light brown to olive in color and most fish have a series of dark bars that adorn the dorsal side. It has large, paddle-shaped pectoral fins on which it will sometimes rest. The dorsal fin is made up of large connected spines that run almost the entire length of the body. The tail is wide and rounded.

"Polypterus" translates to "many fins", referring to one of their defining characteristics: multiple dorsal spines and finlets. These prehistoric looking fish have long, slender, snake-like bodies with protruding nostrils and large, paddle-shaped pectoral fins, which are used for locomotion. Bichirs (bee-shers), as they are also known, also have a modified swim bladder that is like a lung split into horizontal sections. This is an adaptation for survival in low oxygen natural environments which allows them to take gulps of atmospheric air.

These fish prefer long, shallow tanks. You may see them periodically rise to the water's surface to take a gulp of air. You may choose to minimize the ornamentation in the tank to reduce the likelihood of territorial behavior, but Bichirs will be more comfortable with rock caves or driftwood where they can hide, especially during daylight hours. They are nocturnal in nature and are best kept in tanks with subdued lighting.

Bichirs are not terribly aggressive towards other species and can be kept with other fish that will not be mistaken for prey. On rare occasions, they may accidentally bite a tankmate. They have notoriously poor eyesight, and rely on their sense of smell to find food. They may bump into and miss food a few times before they find it, or mistake a tankmate for something to eat. Despite their poor eyesight and normally slow movement, they can move exceptionally fast when necessary and should not be underestimated. They typically have healthy appetites, and will feed on many types of meaty foods from shimp or carnivore pellets to freeze-dried or frozen offerings.
