Salmon Tail Catfish

Introduction: The Salmon Tail Catfish, also known as Neoarius graeffei, is a large, hardy freshwater fish native to the rivers and estuaries of Australia and New Guinea. It is renowned for its strong swimming ability, striking silver coloration, and distinctive salmon-colored tail. Often found in brackish waters, this catfish is well-adapted to a variety of environments and makes a unique addition to large home aquariums.

Scientific Name: Neoarius graeffei

Water Quality and Temperature: The Salmon Tail Catfish thrives in both freshwater and brackish environments. To keep them healthy, maintaining appropriate water conditions is essential:

• Temperature: Keep the water temperature between 70°F to 82°F (21°C to 28°C).
• pH Level: Aim for a pH level between 6.5 and 8.0, as they are tolerant of a wide range of conditions.
• Salinity: These catfish can handle light brackish conditions, with a specific gravity of 1.005 to 1.015. Freshwater is also suitable.
• Water Quality: Frequent water changes (20-30% weekly) are important to manage waste from these large fish and to maintain a healthy, stable environment.

Feeding: The Salmon Tail Catfish is omnivorous and will readily consume a variety of foods:

• Pellets and Sinking Foods: Provide high-quality sinking pellets or catfish food that is rich in protein.
• Live or Frozen Foods: Offer protein sources like bloodworms, earthworms, brine shrimp, or small pieces of fish to mimic their natural diet.
• Vegetables and Plant Matter: Occasionally provide blanched vegetables such as zucchini or spinach to round out their diet.
• Feeding Frequency: Feed once or twice a day, ensuring they receive enough nutrients to support their large size and active lifestyle.

Tank Mates: Salmon Tail Catfish are generally peaceful but can become territorial as they mature. They are best kept with other large, robust fish:

• Suitable Tank Mates: Large cichlids, silver dollars, and peaceful bottom-dwellers like plecos are good companions.
• Avoid Small Fish: Smaller fish may be viewed as food and are best avoided.
• Space Considerations: Due to their size, they require a large tank (at least 150 gallons) with plenty of space to swim and explore.

Substrates and Tank Decorations: Provide a soft substrate such as sand or smooth gravel, as Salmon Tail Catfish like to sift through the substrate in search of food. Add large rocks, driftwood, and submerged branches to create hiding places and mimic their natural river habitats.

Suitable Plants: While Salmon Tail Catfish do not typically disturb plants, they may uproot delicate species due to their active digging. Hardy plants like Java Fern, Anubias, or Vallisneria, anchored to rocks or driftwood, are better suited for their tank.

Sexing: Sexing Salmon Tail Catfish is difficult, as there are no prominent external differences between males and females. Generally, behavior during breeding is the clearest indicator of sex.

Breeding: Breeding in captivity is uncommon due to their large size and the need for specific environmental triggers. In the wild, these catfish migrate to spawn, laying eggs in shallow, sandy areas. If breeding is attempted in an aquarium, providing large, sandy areas and adjusting salinity levels might help simulate natural conditions.

Maximum Size and Longevity: Salmon Tail Catfish can grow up to 24 inches (60 cm) in length. With proper care, they can live for 10 to 15 years, making them a long-term commitment for experienced aquarists.

General Information: The Salmon Tail Catfish is an impressive species, known for its strength and endurance in both freshwater and brackish environments. While not ideal for small tanks or community setups, they are a rewarding species for those with the space and experience to care for them properly.

A Fun Fact: The Salmon Tail Catfish has the ability to tolerate both freshwater and brackish conditions, thanks to its natural habitat in tidal rivers and estuaries. This adaptability makes them a versatile species for aquarists who enjoy experimenting with different water parameters!
