General: Longspine cardinalfish are a peaceful schooling species that originate from the Indo-Pacific region. Both in the wild and the home aquarium, they will prefer to swim around structured areas and coral reefs, while also establishing a hierarchy within the group.
Fecundity: Longspine cardinalfish are mouthbrooders.
Water Chemistry: Longspine cardinalfish prefer water that is 72-78F, a hardness range from 8-12 dKH, a pH ranging from 8.1-8.4, and a salinity level ranging from 1.022-1.025.
Dimorphism: Longspine cardinalfish males will often have a broader jaw than females, which helps them hold onto eggs.
Diet: Longspine cardinalfish will accept flake and pellet food but it should be supplemented with foods rich in protein such as mysis or brine shrimp.
Compatability: Longspine cardinalfish generally do well with most other peaceful saltwater fish and will not eat coral. They may on rare occasions go after smaller invertebrates.
