Port Jackson Glassfish

Pseudoambassis jacksoniensis

The Port Jackson Glassfish is a small, semi-transparent fish native to the coastal waters of eastern Australia. It reaches a standard length of up to 7 cm and is characterized by its silvery body covered with large cycloid scales. A distinguishing feature is its deeply-notched dorsal fin and forked tail fin. Compared to the estuary glassfish, its body is slimmer, with a depth of 33 to 38% of its standard length, and it possesses a full lateral line. This species inhabits estuaries and protected brackish tidal streams, often found in areas with mangroves. Its distribution ranges from Moreton Bay in Queensland to Narooma in New South Wales. The Port Jackson Glassfish is a schooling species that can be found in both marine and freshwater environments, typically at depths ranging from 0 to 6 meters. Feeding primarily on zooplankton, the Port Jackson Glassfish forages from the water surface to the substrate. Currently, the conservation status of this species has not been evaluated by the IUCN.
