Ornate Bichir Facts
- Ornate Bichirs resemble eels, but they are not in the eel family.
- Ornate Bichirs are nocturnal fish that will hide during the day.
- Ornate Bichir are often referred to as living dinosaurs.
Ornate Bichir have a black and yellow patterned body. On the backs of Ornate Bichir are 9 to 11 dorsal spines. Ornate Bichir have long bodies that resemble the look of an eel. Ornate Bichir have a set of primitive lungs that allow them to breathe in water that is low in oxygen. Ornate Bichir can survive outside of water for long periods of time as long as they remain wet.
Telling the male Ornate Bichir from the female can be tricky as both fish remain similar markings throughout their lives. Males typically have wider and thicker dorsal fins, while females have larger bodies.
Ornate Bichir Care
Ornate Bichirs (Polypterus Ornatipinnis) are great additions to any large home aquarium setup, including other large fish species. They will typically ignore other fish in the aquarium, and they are quite hardy fish that can stand a wider range of water parameters. They have a long lifespan and are considered by many to be hardy fish. The key to the success of keeping Ornate Bichirs healthy and happy is to provide them with the appropriate, clean setup. Owners of Ornate Bichir have been able to get them to live well past their projected lifespan this way.
Ornate Bichir Food & Diet
Ornate Bichirs are carnivorous fish. In the wild, they will prey on smaller fish, crabs, insects, snails, worms, other fish eggs, and even smaller Ornate Bichir.
In captivity, Ornate Bichir are picky eaters that will not readily accept dried foods. You will want to offer them a variety of high-quality frozen foods. Brine shrimp and bloodworms are good foods to feed a smaller Ornate Bichir, but you will want to feed large Ornate Bichir foods such as chopped shrimp, prawns, and mussels.
Ornate Bichir Size & Lifespan
On the size scale for home aquarium fish to keep, Ornate Bichir are rather large. In the wild, they can grow up to 24 inches in length, but in captivity, you will see your Ornate Bichir reach a length that is closer to 18 inches. If cared for properly, you can expect your Ornate Bichir to live to be around 10 to 15 years old. If they are kept in perfect condition, it is not unheard of for them to live up to 20 years.
For housing Ornate Bichir, you will want to place them in a minimum of a 180-gallon tank. This will give them plenty of room to explore and hide. It is better to house them in a tank that is wider, as opposed to tall. They prefer waters that are kept at around 77F to 82F and 6.0 to 8.0 pH. It is important for the health and lifespan of Ornate Bichir that their tank remains clean, and you will want to ensure that you have a powerful enough filtration system.
Ornate Bichir are a nocturnal species that will hide during the day and become active during the night hours, so you will not need to worry about what lighting you have as long as you are giving them a day and night cycle. Failing to provide them with a day and night cycle will stress out your Ornate Bichir, and cause them to become more susceptible to ailments and stress.
Ornate Bichir Tank Setup
When setting up a tank for Ornate Bichir, it is important to consider the substrate. Ornate Bichirs like to burrow in the sand sometimes. You will want to choose a substrate that is fine sand. Many plants make for great tank decor, as do rocks that can be used for caves and driftwood. You will be able to notice that your Ornate Bichirs will find places throughout the tank that they will hide and sleep in during the day.
Ornate Bichir Disease
The biggest threat to Ornate Bichir is parasites. Internal or external parasites often infect ornate Bichirs. If caught early on, these parasites can be treated, and Ornate Bichir can get rid of them. Ornate Bichirs can be infected with Ich, which is an infection that shows up on the outside of the fish’s scales in white spots. These spots will grow to take over the fish if left untreated and eventually cause death. Keep in mind when choosing a treatment method that Ornate Bichir are sensitive to some medicines. You will want to avoid any medicine for them that is copper based.
Ornate Bichir Breeding
It is considered a rather difficult endeavor to breed Ornate Bichir in the home aquarium, so most of the Ornate Bichirs you see for sale are wild-caught. There are not a lot of recorded successes in breeding Ornate Bichirs in captivity. Therefore, if you want to increase your Ornate Bichir numbers, you must purchase them.
Ornate Bichir becomes mature enough to breed at around 5 or 6 years. It is possible for a young female to carry underdeveloped eggs, and this can stress out males who are ready to spawn much earlier on.
Once female Ornate Bichir are ready and they have found a mate, you will be able to observe both the male and female Ornate Bichirs locking themselves together at the anal fin. This is when the male fertilizes the eggs. Once this has occurred, the female will find a place to lay her eggs. Ornate Bichir eggs are slightly adhesive and will stick to the surface where they are laid. Female Ornate Bichirs can lay up to 300 eggs at a time.
It takes roughly a week for Ornate Bichir fry to become free swimming. Ornate Bichirs provide no parental support to their fry, and will even eat their own eggs. If you are able, a dedicated breeding setup is a must to ensure that your Ornate Bichir fry survives.
If you can get Ornate Bichir to breed in captivity, it is important that you remove the parent fish away from the eggs as soon as possible.
Ornate Bichir Tank Mates
Ornate Bichir are a good choice for a large community tank that houses the more aggressive fish. Ornate Bichir will typically ignore other fish of different species and only sometimes become aggressive towards their own species. It seems largely dependent on how well they are kept and their personality if they get along with other fish in a community tank.
Examples of compatible fish to house with Ornate Bichir are Oscar fish, some Cichlids, and types of Loaches.
Incompatible fish examples would be any fish that are aggressive, competitive for food, or fish that are smaller than the Ornate Bichir. They will go after and eat any small fish to fit in their mouths.
Are Ornate Bichir Aggressive?

Ornate Bichir and Goldfish

Ornate Bichir and Cichlids
Ornate Bichirs make for ideal tank mates for most Cichlid species. Ornate Bichirs have a more relaxed nature and will avoid other fish. At the same time, they are large and tough enough not to become a meal.
Ornate Bichir and Betta Fish
Even though Betta fish and Ornate Bichir enjoy roughly the same water parameters, it is not a good idea to house any Betta with Ornate Bichir. Ornate Bichir are much larger hunter-fish that will mistake the Betta for food and likely consume them for a meal. Long flowy fins of Betta fish are very tempting for the Ornate Bichir to nip at, and even with fish being fed appropriately, Ornate Bichir will still see Betta as food.
