General Description
The Southern orange-lined cardinal fish (Ostorhinchus properuptus) is a member of the Apogonidae family, known for their diverse shapes and colors. These fish have large mouths and hearty appetites, lending to their suitability for aquarium settings. They typically feed on Artemia, Mysis, and krill, demonstrating a wide-ranging diet.
Aquarium Suitability
Considered suitable for most aquarium setups, these fish are hardy and can coexist with their own species if introduced simultaneously. They are peaceful towards other fish but may engage in intra-species conflicts if space or food is limited.
Demands, Care and Hardiness
The Southern orange-lined cardinal fish is hardy and can thrive in aquariums with appropriate hiding spots such as live rocks. They require a diet rich in small crustaceans and zooplankton. Their nocturnal nature prompts them to seek shelter during the day, often hiding among rocks, corals, or even within sea anemones or sea urchins.
Reef Suitability
These cardinal fish are deemed reef-safe, making them suitable for reef tank setups without posing a threat to corals or other invertebrates.
Aquarium Setup
For a successful aquarium setup, provide hiding places such as live rocks and ensure a minimum tank size of 100 liters. Maintain water conditions within a pH range of 8.1-8.4, a salinity level between 1.020-1.025, and a temperature of 22.2-25.6°C. These fish prefer water with a carbonate hardness (KH) of 8-12.
Behaviour
Southern orange-lined cardinal fish exhibit a peaceful temperament and can be kept in groups, forming small shoals if space permits. They may consume small shrimp and fish, so caution is advised when selecting tank mates.
Feeding and Diet
Their diet should include small crustaceans like krill, Mysis, and Artemia, as well as zooplankton such as Cyclops and pods. They are opportunistic eaters and will consume most food offered in the aquarium.
Habitat and Distribution
Found in the East Indian Ocean, Australia, Japan, Indonesia, New Zealand, and the Central/West Pacific regions, these fish are part of the Cyanosoma complex, which includes several similar species like Ostorhinchus cyanosoma, Ostorhinchus luteus, Ostorhinchus ribrimacula, and Ostorhinchus wassinki. Formerly classified as an Apogon genus member, the species prefer habitats with ample hiding places for security.
