Bichirs are old looking fish that could make a great addition to your tank. These fish are literally living fossils that can adapt to live on land.
They are not fish for beginners as they require certain attention to their care. They are nocturnal animals and quite hardy. If well cared for they can live for around 20 years.
There are about 10 species in this family. All are similar, though they each have slight differences between one another.
