General Description
The Red-striped cardinalfish, also known as the Pearly cardinalfish, belongs to the Apogonidae family under Ostorhinchus genus. These fish are native to the Western Central Pacific region, specifically from the Indo-Malay Archipelago to the Solomon Islands. They are characterized by their delicate nature, reaching a maximum size of 7.0 cm.
Aquarium Suitability
Red-striped cardinalfish are considered suitable for most aquarium setups due to their docile temperament. They can either be kept singly or in a group, and they are known to be shy and peaceful towards other fish in the tank, making them a good addition to community setups.
Demands, Care, and Hardiness
These fish have specific water condition requirements with a recommended temperature range of 22.2-25.6°C, a pH level between 8.1-8.4, a dKH of 8-12, and a salinity level of 1.020-1.025. Red-striped cardinalfish are delicate and sensitive, especially during transportation and acclimatization. They should be housed with non-aggressive tank mates as they are known to hide in sea urchin spines and require sufficient hiding spots within the aquarium.
Reef Suitability
Red-striped cardinalfish are always considered reef safe, making them suitable for reef tank setups. They coexist well with corals and other invertebrates typically found in reef environments.
Aquarium Setup
To create an ideal habitat for Red-striped cardinalfish, it is recommended to have a tank size of at least 100 liters with ample hiding spaces such as rock caves or coral formations. Maintaining a clean environment with stable water parameters is crucial for their well-being.
Behaviour
These fish are usually nocturnal and may seek shelter during the day. They tend to form small shoals and exhibit peaceful behavior towards tank mates but may engage in territorial disputes if there is limited space or food availability in the aquarium.
Feeding and Diet
Red-striped cardinalfish primarily feed on small crustaceans like krill, mysis, and artemia. Their diet can be supplemented with zooplankton such as cyclops and pods. They have a voracious appetite and will consume most food offered within the aquarium.
Dimorphism
Male and female Red-striped cardinalfish may exhibit subtle differences in size and coloration, but further information on dimorphism and captive reproduction aspects of this species is not provided.
Habitat and Distribution
Red-striped cardinalfish are found in the waters of the Indo-Malay Archipelago to the Solomon Islands in the Western Central Pacific. They inhabit coral reefs and lagoons, where they seek shelter among rocks, corals, and sea urchins.
