Means of Introduction: Although it is possible the Hawaiian specimen was a waif from Japan, it is more likely that it was an aquarium release. The Iowa specimen is surely an aquarium release.
Status: Collected in Hawaii and Iowa.
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.
