 Individual fish exhibit well-defined homing behaviour and return to the original location of their group when disturbed.The Banggai cardinalfish often coexists with various anemonefish and anemone shrimp when sheltering in anemones and corals; when found among sea urchin spines, it associates with several other genera of cardinalfish.Following removal of the fish by aquarium collectors, the abundance of associated invertebrates has been shown to decline.
