The life span of the dinosaur bichir is 10 to 15 years. After this period of time, the fish may or may not live another year.



The dinosaur bichir is a hardy fish with few health concerns. However, like all animals, they are susceptible to disease if their environment is not properly maintained. To help prevent disease, it is important to do regular water changes and to keep the tank clean. It is also a good idea to quarantine new fish before adding them to the tank.

A healthy dinosaur bichir will have no difficulty swimming through the water. This fish shouldn’t be seen lying at the bottom of the tank. If you notice your pet lying on its side it’s an indication that something is wrong with it.

The dinosaur bichir’s mouth is equipped with teeth that can be used to eat plants and algae. The teeth can be used to scrape off fish eggs, which will encourage the fish to breed. Be careful not to touch or agitate the fish when it’s eating.

The diet of the dinosaur bichir is made up of a variety of live foods, including insects or small crustaceans. Live foods can be purchased from your pet supply store or you can create your own food by soaking live, small freshwater fish in brackish water and then cooking them with cooking oil to make flake food.

The dinosaur bichir eats bits and pieces of live foods that are similar to the way a human would eat. The fish may be messy because of the tendency to eat live foods, and it’s best to only feed it the food it can eat.

The staple diet of the dinosaur bichir consists of minnows, earthworms, or flake food that contains protozoa and algae. To keep your dinosaur bichir healthy, it is important to provide a varied diet that includes both plant and animal matter.

A good way to do this is to include live foods, such as brine shrimp or bloodworms, as well as vegetables, such as zucchini or spinach.

Dinosaur bichir tank requirements?

When choosing an aquarium for your new pet, you must consider the adult size of the dinosaur bichir. If you have a large fish tank with plenty of room, then you can house more than one dinosaur bichir.

However, if your tank is small or there are other fish in the tank that prey on smaller fish like this one. then it would be best to keep only one per aquarium. The size of the aquarium you choose should be at least 80 gallons. This allows the fish to have plenty of room to swim and hunt for live food and plants.

Water parameters

Dinosaur bichir – tank water parameters

In terms of water conditions, the tank should be in a room at 80-85 F (27-29 C) with a pH level of 6.0-7.5 and a hardness level of 0-20 DH. The size of the tank is directly related to how frequently you must perform water changes. A good rule of thumb is to change 10 to 20 percent of the water each week.

A good aquarium filtration system will keep the water clean and remove excess fish waste, as well as leftover food that may contaminate the water. The filter will also supply oxygen to the water. This is important because the fish need a constant supply of oxygen in order to thrive.

In addition, carbon filters are a good way to remove ammonia and other toxins from the water. The best way to keep the aquarium clean is to do regular partial water changes. This will help keep the water clean and the fish healthy.

Regularly checking water parameters, performing partial water changes, and changing filters regularly will help you maintain a suitable tank environment.

Are there different types of dinosaur bichirs?

There are several different types of dinosaur bichirs. They vary in color, size, and shape. Some have long snouts while others have short snouts. Some of the different types of dinosaurs bichir are:

Saddled bichir

This is the most common type of dinosaur bichir and the one most commonly sold. They have a long snout, with a dark stripe running down their body. Saddled bichirs also have two spots on their body, one near the tail fin and another on the dorsal side of their bodies.

Ornate Bichir

The ornate bichir is a medium-sized fish that can grow to about. It has a brownish-gray base color with lighter-colored spots. The body is covered in ridges that are darkest on the back of the fish. The fins are also colorless with a lighter tone near the tail fin.

Albino bichir

Albino bichirs can be white, gray, or red. They look like saddled bichirs but are usually smaller and have a white belly. The skin on their belly is thinner than that of the saddled bichir, so they are more susceptible to injury.

Delhezi Bichir

This is a large fish that can grow to about. It has a reddish-brown base color with dark lines on its body.


Live plants can be used in the aquarium to keep the water clean and provide a decorative touch. The fancy aquariums that are available today come with plant-growing trays, so you don’t have to worry about purchasing live plants separately.

Aquarium plants can also help keep your fish healthy by providing them with food and shelter from potential predatory fish.

Common aquarium plants:

• Java Fern helps stabilize the pH of your aquarium, making it the best choice for new fish tank owners. Java ferns grow well with no extra care. They are often sold in plants and plant trays at pet stores.

• Java Moss is another plant that helps keep your fish healthy by filtering the water and providing food for your fish. Java moss is also easy to maintain since it doesn’t need a lot of light or warmth to survive.

• Algae is an important part of the aquarium. Its growth helps remove wastes and provides food for your fish. Many people have trouble keeping algae under control, though, so be prepared for a lot of algae growth if you decide to add it to your tank.

Expert Tip: With all that said, most people use live plants in their tanks because they are aesthetically pleasing and help keep the water clean by removing wastes that could harm the fish.



Dinosaur bichirs are a popular fish for hobbyists to breed. They will often lay their eggs on plants, rocks, or even glass. They will need a separate tank that is heavily planted and has very little current.

It is best to isolate the parents from the rest of the fish in your aquarium during the breeding period in order to discourage other fish from eating the eggs. After about two weeks, you should be able to see small transparent eggs. These are about 1 /4 inch (.25 cm) in length.

The parents will probably eat some of the eggs, so check on them daily to make sure they are not eating their own eggs.

Once the eggs hatch, you should remove all of the parents from the aquarium. The new fish will be eaten by other fish, so it is important to keep them separated as much as possible. You can use a net or a sponge to separate them if necessary. The young fish are very fragile, so do not feed them for a few days.
