The Smith's priapiumfish (Phenacostethus smithi) is a brackish-water fish of the family Phallostethidae that grows up to 2 cm.
Description
Smith's priapiumfish is a tiny priapiumfish (Phallostethidae) from fresh and brackish water of Southeast Asia. The species grows to only about 2 cm and has a translucent, slender body; remarkably the male carries a complex copulatory organ ('priapium') under the throat, so fertilisation is internal. As a social fish it hovers in schools just below the surface of calm waters and snaps at microscopic zooplankton. The fish is harmless to humans.
