What makes the Black Shark a popular choice among aquarists?

Its striking all-black coloration and active swimming behavior make the Black Shark an attractive and dynamic addition to spacious aquariums.

Care and Environment

Proper care for the Black Shark involves accommodating its substantial size and specific environmental needs. A minimum tank size of 470 liters (125 gallons) is essential, with larger tanks preferred to provide ample swimming space and reduce territorial aggression. The aquarium should be at least 150 cm (5 feet) in length to allow for comfortable movement.

Water parameters should be maintained within the following ranges:

• Temperature: 24–28°C (75–82°F)
• pH: 6.5–7.5
• Hardness: 10–15 dGH

Strong filtration is crucial to handle the waste produced by this large species and to maintain high water quality. Additionally, a secure lid is necessary, as Black Sharks are known to be proficient jumpers.

In terms of diet, Black Sharks are omnivorous and should be offered a varied regimen that includes high-quality pellets or flakes, supplemented with live or frozen foods such as bloodworms, brine shrimp, and daphnia. Incorporating plant matter like blanched vegetables (e.g., zucchini or spinach) is also beneficial.

When setting up the tank, include sturdy decorations such as driftwood, rocks, and caves to provide hiding spots and establish territories. Be cautious with live plants, as Black Sharks may uproot or consume them; opting for hardy species or artificial plants can mitigate this issue.

How large of a tank is necessary for a Black Shark?

A minimum of 470 liters (125 gallons) is required, but larger tanks are recommended to accommodate their growth and reduce aggression.

Can Black Sharks be kept in planted aquariums?

While possible, they may damage or consume plants. Using hardy species or artificial plants can help maintain the tank's aesthetics.

What should be included in a Black Shark's diet?

A balanced mix of high-quality pellets or flakes, live or frozen proteins, and occasional plant matter ensures proper nutrition.

Origin and Habitat

Native to Southeast Asia, the Black Shark inhabits rivers and streams across countries such as Malaysia, Laos, Cambodia, Thailand, Sumatra, and Borneo. These environments are characterized by moderate to low currents, with substrates ranging from sand to gravel. The natural habitat often includes submerged vegetation and driftwood, providing ample hiding spots and foraging opportunities. Seasonal variations, such as monsoonal rains, influence their behavior, including upstream migrations for spawning.
