One specimen each of two alien fish species, Lepisosteus platostomus Rafinesque, 1820 (Lepisosteiformes: Lepisosteidae) and Hypseleotris compressa (Krefft, 1864) (Percifromes: Gobioidei: Eleotridae), were collected from Sagami-gawa and Kawama-gawa rivers in Kanagawa Prefecture, Japan, respectively. Each individual probably originated from a deliberate abandonment by an aquarist. There is no evidence that either species breeds or is establish at present, but ongoing monitoring is necessary.
