Bala Shark Appearance

The long body and the triangular dorsal fin are two giveaway signs of dealing with a Bala shark. It has several names such as silver shark, tricolor shark, and more, and they have a metallic color that stands out while it swims around in the water. The scales on their bodies are very prominent, with a yellow tail, large bulging eyes, and fins with black tips. There are color variations as well, but this is a fish that is generally very easy to recognize if you have some basic knowledge about the species.

Bala Shark - Care, Feeding, Tank Mates & Breeding

Their adult size is generally somewhere around 13 inches, and it is an active fish that needs a tank where it can swim around and exercise. It is mostly the shape of the body and that triangular dorsal fin that has given it its name (due to the features being considered shark-like), but the large and colorful fins give the Bala shark a unique identity that is about as far from an actual shark as you can come. 

The contrast of that missile-shaped silver body and the yellowfins makes it a sight for the eye in any tank.

When you purchase one of these from a pet store, they will often be quite young still and may only measure about 3-4 inches, and this leads many people to believe that any tank will do and that they are a fish that won’t grow much at all. Don’t fall into this trap, as the silver bala needs a big tank and plenty of space.

Both male and female Bala sharks look very similar, and it can be very difficult for a beginner or an amateur to distinguish the sex of one of these. Some species will have differentiating colors depending on whether they are male or female, but this is not the case with the Bala shark.

The Lifespan of Bala Shark

The typical lifespan of a Bala shark is known to be 10 years. But their life expectancy greatly depends on the care. So, if you offer them proper care, the fish can outlive this expected span. Otherwise, it can die earlier as well. 

Bala Shark Size

The typical Bala shark can typically grow up to 10 inches on the lower end and 14 inches for the larger specimens.

Natural Habitat and Origin 

As far as the natural habitat of the Bala shark is considered, they are known to live in the depths of large and medium-sized-rivers. Naturally found in the rivers and lakes of Southeast Asia.

Interestingly, Bala sharks prefer to live in clean fast-flowing waters. It is the main reason you will find them in the middle regions rather than the top or the bottom. Also, it spends most of its time swimming around. 

Talking about the origin, this fish is known to come from the Malay Peninsula, Sumatra, and Borneo.

While the name indicates that you are dealing with a shark, the balantiocheilus melanopterus is just a fish that strongly resembles a shark, but this has done nothing to stop its popularity from spreading. We say that it was a native to these areas, in the past tense, because the wild population has been drastically reduced over recent years. 

Some even argue that these sharks seem to have become completely extinct in some areas where they would once thrive. The reason for this has not been determined, and it is possible that it could be a result of contamination or overfishing.

The Bala shark can be found on the IUCN Red List of Threatened Species, and it has been listed since 1996, and as a result, most Bala sharks you see in aquariums today were born in captivity and farm bred. It is the reason why you can own one despite their endangered status, as they are only threatened as a species in the wild, but there is plenty of farm-bred fish destined for the aquarium business.

Its popularity as an aquarium species has increased steadily over recent years, and it is not hard to see why when you spot one in an aquarium for the first time. It is an impressive fish with that shark look, without actually being a shark, and it is surprisingly easy to care for considering it being on the larger side.

Bala Shark Care and Tank Set-Up 

Bala sharks are omnivores, which means that they eat both other animals and plants, and the truth is that these fish are likely to consume anything you put in the tank, provided it is edible. They are not picky, so it will be up to you to make sure you give them a nutritious diet. The good idea is to feed high-quality flakes as the main meal and let them have live food such as shrimp a couple of times a week.

Bala Shark Care and Tank Set-Up 

As for the Bala shark’s diet and feeding instructions, this is a fun fish to feed just because it can get so excited! Many experts recommend feeding Bala sharks two times per day instead of just doing one daily feed. It is because the fish tends to overeat if given a chance, and their metabolism should have their daily food intake split in two. If you can allow your Bala shark to eat more than once a day – do so, as it will likely help maintain your swimming pet healthy for a lot longer. A happy and healthy shark will live a longer life, and an adequate diet plays a big role in their overall wellbeing.

Tank Conditions

It is advisable to get a long tank for Bala sharks for the simple reason that they like to swim, and if you plan to keep a school of four fish – you need a tank that can hold at least 120 gallons of water. After all, the adult size of one of these Bala sharks is 13 inches. Another good idea is to keep an aquarium cover on the tank, as this gorgeous silver shark tends to jump straight out of the tank when (and if) they get scared. You don’t want to come home and find your tricolor shark lying there on the floor.

The next step is to decorate with appropriate plants, and you will want to make sure that you don’t add plants that take up too much space. Why? Because the Bala shark needs to be able to swim.

One thing you can do is to use plants that cover the surface of the water without covering too much at the bottom, as these will work as a natural cover to prevent your Bala sharks from accidentally jumping out of the water. Driftwood and large rocks are other good additions you can use to make your tank feel more like home to the Bala shark.

Bala sharks are very sensitive to drastic temperature changes in the water, and they don’t do well with very low temperatures. In fact, this could result in them developing something known as white spot disease. 

Keep the water temperature somewhere between 72 and 82 degrees Fahrenheit. The best way to keep these swimmers from getting diseases is to keep the water as clean as possible and provide an environment where they do not experience stress, anxiety, or distress.

Keeping less than four could result in some unhealthy bullying becoming a problem in the tank, and too many are only too many if you don’t have a tank the right size. These are big fish, and they need their space.

Other peaceful fish of a similar size could also make good tank mates, and the Bala shark makes a good community tank fish as long as there is enough space. You should avoid having small fish like tetras in the same tank as the Bala shark might eat them, and any type of shrimp or vertebra is also a bad idea due to this being a part of a Bala shark’s natural diet. 

Choose thank mates wisely, and you might want to avoid adding fish that scare easily as the Bala shark tends to swim around fast and vigorously, which could startle some species.

Bad Bala Shark Tank Mates

Breeding Bala Shark

While some claim to have bred these fish in an aquarium, it has not been documented or proved and is considered to be highly unlikely. An aquarium simply does not give the fish what it needs to breed, and instead, most Bala sharks are bred in fish farm facilities, mainly in Asia. 

The reason why they are so difficult to breed yourself in your aquarium is likely to have to do with fish tank size and possibly the water quality, so if you had hopes of breeding Bala sharks – you are unfortunately up for a bit of disappointment.

Males and females can also be difficult to distinguish when it comes to ball sharks, as they tend to look very similar. When the female is ready for breeding, her body might become slightly plumper, but due to the lacking conditions in an aquarium – this is likely not something you will ever get to see.

Some do claim to have done it successfully, though, so if you are eager to give it a try, make sure you set up a separate breeding tank for the fry. If you were to be successful, the best strategy is to remove the adult Bala sharks from the water to prevent them from eating their own offspring. That said, you do have to be prepared for failure due to the complicated breeding nature of the Bala shark.
