Ambassis agassizii
Endangered population
The Olive Perchlet has an oval shaped body. Other characteristics include:
It can grow to about 70-80 mm but more commonly seen at less than 60 mm.
Olive Perchlets are a small native fish that occur in both eastern (coastal) and western (Murray-Darling) drainages, but these populations may be genetically distinct. The western population of the Olive Perchlet was once widespread throughout the Murray-Darling system of South Australia, Victoria, western New South Wales and southern Queensland. This population has suffered a serious decline and is now found only at a few sites in the Darling River drainage.
The Olive Perchlet inhabits rivers, creeks, ponds and swamps with slow flowing or still waters. They are usually found in sheltered areas such as overhanging vegetation, aquatic macrophyte beds, logs, dead branches and boulders during the day, and disperse to feed during the night.
