Bichir fish is a family of freshwater fishes with ray fins that are native to the continent of Africa where they are well spread out in different parts. There are up to 14 genera of the fish that are known currently all of which are evenly spread out in Africa. The fish are known to inhabit freshwater basins in Africa and parts of the Indian sub-continent. The fish in the wild prefers muddy water with a bottom that is silted but sometimes it even lives in bogs.

Bichir Overview

There are just various species of bichir that will survive in tank conditions such as the ornate bichir, Senegal bichir, barred bichir, and marbled bichir. The fish has rather poor eyesight but a very strong sense of smell that it uses to navigate the waters that it inhabits in the wild.

Bichir Care

Considering the level of the hardiness of Bichirs, these exotic Bichirs are very easy to keep healthy and happy. But for that, you will have to make sure that you have the correct tools and information. These creatures are listed as nocturnal carnivores, and they are from the Congo River’s shallow and muddy waters. They prefer to breed during rain seasons and eat at night.

Some studies have suggested that Bichirs are peaceful for different predatory fish species and can be a perfect companion for other peaceable and medium-sized species. In terms of feeding, you can offer pellets to supplement a mixed diet of living and frozen prey, but that should not be the only source for consistent nutrition.  Another interesting thing that you should consider if you plan to keep Bichir is that they are great escape artists. As they need a sufficient amount of atmospheric oxygen to survive, you should offer sufficient space above the surface to let them breathe properly. But take care of the small openings near the lid as they can come out of the tank that way.

Appearance of Bichir Fish

Bichir

The body of the fish is long looking almost similar to that of an eel and it has unique dorsal finlets. The scales of the fish are diamond-shaped and a close look at them reveals to you that they are flexibly joined together. The body of the fish is very strong and it is interesting that the fish can still breathe even when out of the water.

There are 12 different species of Bichirs, and all of them share some similar characteristics. They all have a snake-like body and have multiple fins and dorsal spines. Well, their eyesight is low, and to overcome this issue, they come with protruding nostrils that can help them identify their foods by pinpointing the smell’s source. 

Even though you will not find many differential factors among the females and males, female Bichirs are larger than the males. On the other hand, males come with thicker and wider dorsal and anal fins.

Types of Bichir

Some of the common types of Bichir are:

The Dinosaur Bichir

Bichir Temperament And Behavior

One of the most important things that you should keep in mind when taking good care of Bichir fish is their behavior and temperament. Even though they are not considered aggressive fish, they do have little aggressive tendencies that every aquarist should manage. 

Considering that Bichirs are carnivores, it can be concluded that you may face some issues when you keep them with other fish in the same tank. Any fish smaller than their size can be a target for the Bichirs.

Apart from a little aggressive temperament, generally, they are quite active. In general, Bichirs are bottom-dwellers, but they also frequently come to the surface for fresh air. So, they always keep swimming up and down in a tank, making them fun creatures. As they are nocturnal, they remain active during the night.

Keeping the Bichir Fish in Tank

Keeping Bichir in a tank is not complicated and even an aquarium beginner can still set up a tank for keeping the fish successfully. The species of this fish are not demanding at all and as long as the basic tank conditions are maintained it will just do well in captivity.

Bichir Fish in a Tank

Another thing to keep in mind if you are planning to keep the fish in a community tank with other fish is that it is rather slow in finding its food. This means that if it is housed together with other fish that are fast and swift at eating available food, it might find difficulty feeding well. This, therefore, calls on the aquarist to be keen when administering food to the fish when in a community tank. Ensure that the fish has sufficient food and is not left starving.

Bichir Care & Tank Set-Up

Tank requirements

Because the fish can grow to be very large it is best to give them a big enough tank that will give them ample space for swimming. To keep one Bichir, therefore, you will need to have a tank that is at least 50 gallons or even larger.

Bichir Care & Tank Set-Up

Here below are some important tips for keeping the successfully in a tank:

  • Please ensure that No products found. to prevent the fish from jumping out of the tank. It is notoriously known to jump out of even large tanks.
  • The tank water pH should be 7 and for the water hardness or softness the fish will just thrive in both.
  • You can use a variety of tank decorations which may include rocks and aquatic plants. The rocks will provide cave-like structures where the fish can hide.
  • Bichir is a bottom dweller and feeder therefore the substrate should be chosen with care. A great choice can be a thin layer of sand that will be easy to clean when need arises although you can as well use small-grained gravel.
  • As you choose the stones to use for decoration in the tank, it is best to choose those that are smooth. You can also use ceramics although these will not give a natural look that impresses so many people.
  • For filtration purposes it is best to installation a powerful canister filter that will be capable of use both biological and mechanical filtration. This filter will help with keeping the water clean from the protein leftovers that can quickly make the water highly toxic for the fish.

Feeding Bichir

Bichir is a predatory fish that should be fed on live foods which include; bloodworms, calamari, frozen shrimp, meat, and earthworm. You can as well give the fish artificial food such as fish flakes and pellet food but it must be noted that his kind of food is not natural for the fish.

Feeding Bichir

It is best to lower in small portions of food in the tank and wait for the fish to feed before offering more food. This will help to ensure that fish doesn’t leave much food that will serve as a leftover to make the tank water toxic.

Compatibility with other fish in the tank

Finding a perfect compatible tank mate for your Bichirs is all about considering the aggression and size of your fish. As discussed earlier, they are carnivores and can become very aggressive. That suggests any fish species smaller or their size will not be a good option. You, Bichir, can eat them. You should go for the fish that are a little bigger than the Bichir while looking for tank mates. Because they will not be confused with food, they can bully them. Some of the best tankmates are:

You should also ensure that the tankmates allow some foods to reach the tank’s bottom part. If this is the case, the Bichirs will become underfed and start developing different health issues. 

It may be noted that you can keep two Bichirs in one tank. Well, most aquarists don’t prefer to do that; you can give this a try. But remember that the tank size should be large enough to accommodate two fully-grown Bichirs.

Sexing

There isn’t quite a distinctive difference of the sexes although there are some slight differences. The males have wider and thicker anal and dorsal fins but the females are generally wider in their genera size.

Breeding Bichir

Bichir is quite difficult to breed in the home aquarium and most of the fish you find in pet shops were most probably captured in the wild and put in tanks for sale. There is no categorical explanation of the process of breeding the fish in home aquariums because most aquarists who have attempted this have had little success if any. This, therefore, means that if you need to have more of them you may need to get one from the pet store.

Breeding Bichir

Some experts suggest using a perfect combination of soft and little acidic water. Besides, you should increase their overall protein intake level during their breeding.

The male Bichir generally pursues the female Bichir and headbutt her. This process can sometimes last for two to three days. Once done, the female Bichirs will find a place to lay the eggs. They generally choose bushy plants. So, don’t forget to add such plants to the tank. 

Once the breeding process is done, you will have to remove them from the tank and feed the fry. To help them grow faster, you can offer them micro-worms and brine shrimp.

Conditioning Your Bichirs For Spawning

They don’t generally breed in captivity except in large ponds in tropical areas. They rarely breed in the tank as they prefer some changes in the climate, like weedy marsh plants, cool spells, and more. As most of them are wild-caught, they sometimes fail to reproduce. However, there are certain things that you can follow to make your aquarium a perfect breeding place.

They have a threadlike structure, and you can see them attached to the skin of your Bichir. These parasites can develop irritation, and due to that, your Bichir will start rubbing the body against the wall substrate and begin rolling around to remove the parasites from the gills and skin. If you see such a condition, you should start the treatment as soon as possible. Most of all, the flukes can be eliminated using over-the-counter medications, and you can easily get them from any good fish stores as well as online.

It is believed that in a captive condition, the average lifespan of a Bichir is around 15 years. But by offering good care and treating the health issues immediately, you can allow them to survive up to 20 years.

Healthy Bichirs

Tapeworms In Bichirs

Tapeworms are quite common among the wild-caught Bichirs. Generally, they lay eggs in the intestines of the fish. Then the eggs are moved out from the body in the waste and then eaten by invertebrates or crustaceans or invertebrates. After that, the Bichirs eat the new host, ingesting the tapeworms. 

So, to make sure that your new Bichirs don’t pass those parasites to the other species living in your aquarium, you should quarantine them first into a separate tank for one month and notice their behavior. If everything is good, you can move the Bichirs to the tank. Besides, you can try to treat your Bichirs for parasitic infections while keeping them in quarantine to kill any parasites that may be lurking undetected.
