📖 Overview
Occurs in the shoreline of the Lake Mahalona. Found in a moderately steep inshore habitat characterised by mangroves over gravel substrate in the shallows, turning to predominantly rocks alternating with sand and mud in about two meters depth. The habitat was also composed of submerged dead wood, especially in less than two meters depth. Occupies shallows up to about 2 meters depth, but not present in depths between 2 and 12 m, the maximum depth visited by diving at sampling site. Occurs sympatrically with other fish species which include Telmatherina celebensis, Paratherina striata, P. wolterecki, Oryzias marmoratus, Mugilogobius latifrons, M. rexi, Glossogobius intermedius and G. matanensis .
