At a glance the quick version
Looks how to spot one
Torpedo-shaped scaled minnow
A sleek, streamlined silver fish with large eyes and tall fins. The dorsal, tail, anal and pelvic fins are edged in black, which gives the striking three-tone look behind the name tricolor shark. Grown females are deeper-bodied than males.231
Personality what they are like
Calm and non-aggressive, but its size and energy suit it to large, sturdy tankmates rather than small or slow community fish. Within a group the fish settle into a pecking order.2
Daily activity how busy a day looks
A fast, open-water swimmer that needs a long tank with plenty of free swimming room. It is a strong jumper, so a tight-fitting lid is important.23
Grooming and care the hands-on bits
Large, well-filtered tank with regular water changes. Water: about 20-28 C, pH 6.0-8.0 (near neutral preferred), hardness about 2-15 dGH.21
Home where they are happiest
A big aquarium: Seriously Fish suggests a base of around 240 x 60 cm (about 860 litres) for adults; FishBase gives a minimum length of over 150 cm. Open space down the middle with planting or decor at the edges.21
Food basics what goes in the bowl
Omnivore. In the wild it eats small crustaceans, insects and their larvae and some plant material; in the aquarium it takes good dried foods with small live or frozen items and plenty of vegetable matter.12
Company who they like around
The story where it all began
Pieter Bleeker described the species in 1850. It became a staple of the aquarium trade, while wild numbers dropped in many of its native rivers after the 1970s. Today the fish on sale come from commercial breeding farms.32
Fun facts for the dinner table
- 1
Despite the name it is not a shark at all but a member of the carp and minnow family, Cyprinidae.3
- 2
It earned the name tricolor shark from its silver body and black-edged, yellowish fins.1
- 3
It is a skilled jumper, so aquariums housing it need a secure cover.3
- 4
Captive stock is produced on fish farms, which means the trade does not depend on wild-caught fish.2
Recognised by the official bits

Owner questions the things everyone asks
How often should I feed my Bala Shark?
Feed your Bala Shark once a day. Furry Diary's starting plan suggests daily feeding, and you can adjust the amount based on what your fish eats in a few minutes.2 Pet Wiki plan
What does a Bala Shark eat, and what should it never eat?
Your Bala Shark is an omnivore and enjoys good dried foods, small live or frozen items, and plenty of vegetable matter. Avoid feeding it anything that is not specifically designed for aquarium fish, and never give it human food or large prey.21
How much space does a Bala Shark need?
A Bala Shark needs a very large aquarium; Seriously Fish suggests a base of around 240 x 60 cm (about 860 litres) for adults. It is a fast swimmer that needs plenty of open water, so a long tank is essential.21
What temperature, light or water does a Bala Shark need?
Keep the water temperature between 20-28°C, pH near neutral (6.0-8.0), and hardness about 2-15 dGH. Provide moderate lighting and a tight-fitting lid, as Bala Sharks are strong jumpers.231
How often should I clean a Bala Shark's home?
Furry Diary's starting plan suggests a weekly water change of about 30 to 50% of the water, along with a weekly water test. Rinse the filter every two weeks to keep the tank clean. Pet Wiki plan
Can a Bala Shark live with others?
Yes, Bala Sharks are shoaling fish and should be kept in a group of at least five. They are calm and non-aggressive but need large, sturdy tankmates due to their size and energy.21
How long does a Bala Shark live?
The lifespan of a Bala Shark varies depending on care and environment. For specific information, ask a good breeder or an exotic-pet vet.
Can I handle a Bala Shark?
It is best not to handle your Bala Shark, as it is a delicate fish that can be stressed or injured. Always use a net and keep handling to a minimum.2
