Mimagoniates is a genus of characid fish from rivers and streams in southern and eastern Brazil, northeastern Argentina and Paraguay.[1][2] Commonly known as croaking tetra or chirping tetra because they can produce sounds, some of these fish were formerly included in Glandulocauda. They have a supplementary breathing organ located above the gills which makes a faint chirping sound when these fish come to the surface to gulp air. It also plays a role in courtship as the male chases and hovers near the female while taking gulps of air and expelling it to make a rhythmic noise.[3] Croaking behavior may have evolved from a behavior called "surface nipping", which occurs when the fish is searching for food. This gulping of air has no useful respiratory function.[4]
