Polypterus ornatipinnis
A large bichir whose grey-brown body is covered in a yellow net-like pattern. It comes from the Congo basin and reaches 60cm. A nocturnal predator, it needs a tank with a large floor area and a tight-fitting lid, and is one of the most popular ancient fishes in the hobby.
Polypterus ornatipinnis is an ancient fish of the family Polypteridae found in the Congo River basin and Lake Tanganyika. FishBase records a maximum of 60cm TL, 9-11 dorsal finlets and upper and lower jaws of about equal length. The yellow net-like pattern over a grey-brown ground is the most ornate in the genus and gives the fish its name. Seriously Fish suggests 25-28C, pH 6.0-8.0, 5-25 dGH and a 180 x 60cm base of about 648 litres. Floor space matters more than depth, and sand with driftwood caves suits it. The swim bladder works as an accessory breathing organ, so the fish must reach the surface for air and will drown if denied it. It is a strong swimmer and an escape artist, so a tight lid is essential. Nocturnal and weak-sighted, it hunts by smell and treats any fish that fits in its mouth as food. The IUCN lists it as Least Concern and it is not covered by CITES.

Seriously Fish calls for a 180 x 60cm base of about 648 litres for an adult. Prioritise floor space over depth and build caves from a soft substrate, driftwood and smooth rocks. It is an escape artist, so a heavy, gap-free cover is essential.
Seriously Fish gives 25-28C, pH 6.0-8.0 and 5-25 dGH; FishBase records 26-28C in the wild. It tolerates a wide range of chemistry but is a heavy feeder that fouls water quickly, so allow generous filtration.
It cannot be trusted with anything it can swallow but is otherwise fairly peaceful. Other Polypterus, Synodontis, Datnioides, knifefish and medium to large characins are suitable companions.
Carnivorous and often reluctant to take dried foods. Prawns, earthworms, mussel and lancefish, live or frozen, form the staple. It feeds by smell, so make sure slower individuals actually reach the food.
It has been bred in aquaria but published detail is scarce. It spawns in the rainy season in the wild, so changes in temperature and chemistry are the likely trigger. The male cups the eggs in his anal fin, fertilises them and scatters them among plants; they hatch in three to four days.
It breathes air and will drown if it cannot reach the surface. Although hardy, it grazes and scrapes easily, so choose decor without sharp edges. The IUCN rates it Least Concern and it is not listed by CITES.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The ideal temperature for Ornate Bichir is 25〜28℃. Avoid sudden temperature changes and maintain a stable environment.
The average lifespan of Ornate Bichir is 10-15 years. With proper care and nutrition, they can live a long and healthy life.
Ornate Bichir typically reaches Up to 60cm TL as an adult. Size may vary depending on care conditions and individual genetics.
Ornate Bichir feeds on: Meaty live and frozen foods such as prawns, earthworms, mussel and lancefish. Aim for a balanced diet with appropriate feeding frequency.
