Australian Barramundi: A Hardy and Impressive Choice

The Australian Fish Barramundi (Lates calcarifer), also known as Asian Sea Bass, is a large and versatile fish native to Australia. Known for its adaptability and striking silver sheen, this species is a favourite among aquarists with large tanks and a passion for unique, impressive fish. Its ability to thrive in both freshwater and brackish environments makes it an exciting addition to specialized setups.

Size and Lifespan

Barramundi can grow up to an impressive 120 cm in the wild, but in aquariums, they typically reach 60–80 cm. With proper care, they can live for 10–15 years, offering long-term enjoyment and a standout presence in any large tank.

Tank Requirements

A spacious tank of at least 1000 liters is essential for these active and fast-growing fish. They prefer water temperatures of 22°C–30°C and a pH range of 7.0–8.5. Providing strong filtration and maintaining excellent water quality is crucial for their health. Add rocks, driftwood, and open swimming spaces to create a comfortable environment. For brackish setups, include a small amount of marine salt to mimic their natural habitat.

Tank Mates

Australian Barramundi fish are predatory fish, so choosing tank mates requires careful consideration. Suitable companions include other large, robust species like Archerfish, Scats, and Monos. Avoid keeping them with small fish, as they may see them as food. Ensure the tank is spacious enough to minimize competition and aggression among tank mates.

Feeding Australian Barramundi

Barramundi are carnivores with a hearty appetite. Feed them a diet of high-quality pellets designed for large predators. Supplement with live or frozen foods such as prawns, fish fillets, and worms. Providing a varied diet not only supports their rapid growth but also enhances their overall health and vitality.

Breeding Australian Barramundi

Breeding Barramundi in home aquariums is challenging due to their large size and specific requirements. In the wild, they migrate between freshwater and estuarine environments to spawn. Successfully breeding them in captivity often requires specialized facilities and precise control of water conditions.
