FBname: Northern trout gudgeon
Comments: Found in a wide range environments from desert bores and muddy swamps to clear jungle streams.  Inhabits rivers, creeks and billabongs, in quiet or slowly flowing sections among vegetation or rocks.  Young fish feed mostly on microcrustaceans.  Adult fish prey upon insects, crustaceans, worms, mollusks, fishes and plant materials.  Spawns during the rainy season (November to March).  Female produces several batches of 100-500 eggs which are deposited on rocks or logs.  The males guards and fans the eggs until hatching, which takes about 8-10 days.  The population on the Barkly Tableland (Northern Territory) may eventually prove to be a separate species (Ref. 44894).
