This school of Northwest Glassfish (Ambassis sp.) was filmed in a rainforest spring tributary of the Finniss River near Batchelor in the Northern Territory of Australia. Although this species is very common it remains officially undescribed. At one stage it was referred to as Ambassis muelleri which is now a synonym of Ambassis agassizii, a fish found through much of the Murray River system much further south.
