Introduction
The Salmontail catfish, scientifically known as Arius leptaspis, is a captivating species that appeals to aquarists due to its impressive size and unique appearance. Native to Australia and New Guinea, this catfish is renowned for its salmon-colored tail and active swimming behavior. While its striking features make it an attractive addition to large aquariums, potential keepers should be aware of its substantial growth potential and specific care requirements.

Its distinctive salmon-colored tail and dynamic swimming patterns add visual interest to spacious aquariums.
Is the Salmontail catfish suitable for beginner fishkeepers?
Due to its large size and specific care needs, it is better suited for intermediate to advanced aquarists.
Care and Environment
Proper care for the Salmontail catfish involves attention to tank size, water parameters, filtration, and diet. Given their potential to grow up to 80 cm (31.5 inches), a minimum tank size of 400 liters is recommended for a single fish, with larger volumes necessary for groups. Maintaining water temperatures between 20°C and 30°C (68°F to 86°F) and a pH range of 6.5 to 8.0 is essential. Efficient filtration is crucial due to their significant waste production; canister filters are often preferred for their capacity and effectiveness. A soft substrate, such as sand or smooth gravel, is ideal to prevent injury to their sensitive barbels. Feeding should include a variety of sinking pellets, live or frozen foods like bloodworms and brine shrimp, and occasional vegetable matter to ensure a balanced diet.
