Means of Introduction: Aquarium escape (Devick 1991b), accidental introduction (Devick 1991a).
Status: Established in Hawaii.
Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
