Mimagoniates is a genus of characid fish from rivers and streams in southeastern, southern and central-western Brazil, northeastern Argentina, and Paraguay. [1] [2] The individual species generally have relatively small ranges and two, M. lateralis and M. sylvicola, are considered threatened by Brazil's Ministry of the Environment. [3]
Commonly known as croaking tetra or chirping tetra because they can produce sounds, [4] some of these fish were historically included in Glandulocauda and together with Lophiobrycon they form the tribe Glandulocaudini. [2] Mimagoniates 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. [4] 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. [5] They are small fish, up to 3–6.1 cm (1.2–2.4 in) in standard length depending on the exact species. [1]
There are currently 7 recognized species in this genus: [1] [2]
