Comments: Inhabit coastal lagoons and near estuaries, usually in freshwater (Ref. 27363, 59043).  Gregarious.  Adults feed on zooplankton.  Mature adults spawn for the first time at 1-2 years.  Eggs are deposited among aquatic vegetation (Ref. 59043). Maximum length estimated from the fact that the congeneric <i>Odontesthes incisa</i> has a common length of 10 cm TL.
