Bala Shark Overview


Bala Shark (Balantiocheilus melanopterus) is a freshwater aquarium fish. The fish belongs to the family Cyprinidae that includes the barbs, barbells, minnow, and carps. It is also known as the silver shark, silver Bala, shark minnow, and tricolor shark.


The word shark is a misnomer since it doesn’t belong to the shark family. It is named due to the rigid and triangular dorsal fin and the elongated body similar to a shark. While the fish does look imposing, it isn’t aggressive.


Natural Habitat


Bala Shark is native to rivers, lakes, and other water bodies in Southeast Asia. It is commonly found in fast-moving rivers in Sumatra, Kalimantan, Cambodia, and Thailand. However, their numbers are dwindling fast in the wild due to overfishing.

The fish is listed on the IUCN Red List of Threatened Species. Most of the Bala Shark available for sale online has been bred privately or raised on fish farms.

It would help if you placed the aquarium in a quiet place where the fish is less likely to get scared. It is essential as the fish can hurt itself when swimming fast inside the aquarium in panic.


A benefit of keeping Bala sharks inside the aquarium is that the fish will forage for food items at the tank’s bottom. They will diligently eat leftover food items at the bottom that will keep the tank clean.


The fish picks up the food item daintily with little disturbance of the plants or substrates. You will have to clean the tank less often when you add the fish to your aquarium.

Bala Sharks are river fishes that are accustomed to slow-moving water. You should buy a filter that will cause constant water movement and provide enough oxygen. Consider buying a large canister filter to ensure a steady movement of water and adequate availability of oxygen.


Water should be kept as clean as possible. You should replace the water every week or when it becomes visibly dirty.

Changing part of the water every week will reduce nitrites inside the water. Your fish will feel less anxious and less likely to get sick when the water is kept clean.

Install a sponge filter in the cover of the tank to keep the water tank clean. The sponge filter will keep the water clean without creating a lot of suction that will put the hatched fry in danger.


After the mating process, female fish will scatter the eggs around the tank that will be fertilized by the male. The filtration inside the tank provides sufficient current to allow the sperm to spread over all the eggs.


You must keep the parents in a separate tank once the eggs are laid and fertilized. Bala sharks are prone to eating their eggs and the newly hatched fry. You should monitor the breeding process to remove the parent fishes once the eggs are fertilized quickly.


Once Bala sharks hatch from the egg, you should feed a varied diet of commercial fry food. Should feed baby fish in small amounts multiple times a day. The young fry will multiply, and you may soon have to transfer them to a bigger tank so that they have enough space to swim.
