Ambassis macleayi

Ambassis macleayi, commonly known as Macleay's glassfish, Macleay's glass perchlet, Macleay's perchlet, reticulated glassfish, reticulated perchlet, or network perchlet, is a species of freshwater fish in the family Ambassidae. It is native to northern Australia and the trans-Fly River region of New Guinea. It is a fish with a vertically flat, narrow body and a standard length generally between 35 and 45 mm (1.4 and 1.8 in), with large specimens reaching 77 mm (3.0 in) long. It generally eats water fleas and other small invertebrates. This fish is considered to be a least-concern species according to the International Union for Conservation of Nature (IUCN), although it could suffer from habitat degradation due to feral pigs and invasive water plants such as the water hyacinth. The fish is suitable for aquarium use in tanks containing other non-aggressive species.
