Polypterus senegalus is one of the smallest species of bichir, and one of the most popular too. Bichirs are also sometimes known as dragon eels or dinosaur eels, but they're not closely related to true eels. These ancient air-breathing fish have existed almost completely unchanged since long before dinosaurs walked the Earth. Bichirs can also walk on land for a short period of time, to migrate to different bodies of water (Although we don't recommend taking your bichir for a walk!). Senegal bichirs reach a maximum length of about a foot, but many don't exceed 10". While they can and will eat fish that will fit in their mouths, they are very peaceful with tankmates too large to make a meal out of. Bichirs relish any meaty foods such as sinking pellets or frozen foods. Make sure you have a tight lid with no gaps, as bichirs are very good at escaping tanks! Packing tape works well for covering gaps where cords or filters exit the tank.
These are juveniles, around 3-4" long.
