Spotted African Lung Fish

Spotted African Lung Fish: A Unique Freshwater Aquarium Addition

The Spotted African Lung Fish is an extraordinary species prized by freshwater aquarium enthusiasts for its distinctive appearance and fascinating behavior. Known scientifically as Protopterus dolloi, this lungfish stands out with its elongated body, spotted pattern, and ability to breathe air, making it a captivating and hardy choice for experienced aquarists.

Size and Growth

Adult Spotted African Lung Fish can grow impressively large, often reaching lengths of up to 24 to 36 inches (60 to 90 cm) in captivity. Their size makes them a centerpiece fish that requires ample space and commitment to care. Prospective buyers often wonder how big these lungfish get and how their growth impacts tank requirements.

Temperament and Behavior

This species exhibits a generally peaceful yet solitary temperament. Lungfish are bottom dwellers and tend to be shy, spending much of their time buried in substrate or hiding among decorations. While not aggressive, they can be territorial, especially in confined spaces. Understanding their temperament is crucial when considering tank mates and overall aquarium setup.

Recommended Tank Size

Due to their large adult size, a minimum tank size of 125 gallons is recommended to provide adequate swimming space and maintain water quality. A spacious, well-covered tank is essential since lungfish are known to be escape artists. The tank should include soft substrate for burrowing, hiding spots, and minimal strong water currents to mimic their natural habitat.

Water Parameters

• Temperature: 72–82°F (22–28°C)
• pH: 6.5–7.5
• Hardness: Soft to moderately hard water

Maintaining stable water parameters is important to keep your lungfish healthy. They are tolerant of a range of conditions but prefer slightly acidic to neutral pH and warm temperatures. Regular water changes and a high-quality filtration system will support their well-being.

Diet and Feeding

Spotted African Lung Fish are carnivorous and thrive on a diet rich in protein. Their diet should include live or frozen foods such as earthworms, shrimp, bloodworms, and feeder fish. They also accept sinking pellets formulated for carnivorous fish. Owners often ask about feeding frequency and the best food types; feeding 3–4 times weekly with a varied diet will promote optimal health.

Compatibility with Other Fish

When considering tank mates, it’s important to note that lungfish may consume smaller fish due to their predatory nature. They are best kept either alone or with large, robust species that can coexist peacefully. Avoid housing them with small, delicate, or slow-moving fish to prevent predation and stress.
