Comments: Occurs in rivers and swamps (Ref. 57235).  Usually associated with standing or slow-flowing, shallow waters (Ref. 27732).  Abundant in flooded rice-paddies, canals and ditches.  Avoids large rivers and only moves from temporarily inundated habitats if necessitated by seasonal habitat disappearance .  Moves into seasonally inundated areas as soon as they are flooded.  Feeds on zooplankton, terrestrial insects and aquatic insect larvae.  Occasionally sold fresh and used to make prahoc (Ref. 12693, 57235).
