Choosing Freshwater Sharks for Your Aquarium

If you’re looking for a small, easy-to-keep freshwater shark, consider the rainbow shark. Growing to about 6 inches long, rainbow sharks thrive in planted tanks. They require a smooth or sandy substrate to protect the delicate barbels around their mouths.

Another option is the red tail shark, which also grows to around 6 inches. However, they are more aggressive and can be challenging to house in a community tank. Avoid iridescent sharks if size is a concern; they may look small in pet stores but grow very large, making them unsuitable for most home aquariums.

How to Set Up a Shark Aquarium

Before selecting a freshwater shark, research its specific care requirements. However, most freshwater sharks share common needs for tank setup and environment.

Tank Size and Environment

Tank size is critical. Freshwater sharks are large fish, requiring tanks of at least 100 gallons. Larger species may need up to 300 gallons. Most sharks prefer heavily planted tanks with ample hiding spots. Many freshwater sharks originate from large rivers in Central and South America or Southeast Asia, so recreating this environment is beneficial.

While artificial plants work, live plants are better. Include rocks, driftwood, and caves at the bottom for hiding and territory establishment. Freshwater sharks should only be housed with fish that are too large to eat and have a compatible temperament.
