Semaprochilodus insignis

The kissing prochilodus or flag-tailed prochilodus (Semaprochilodus insignis) is a species of South American freshwater fish in the family Prochilodontidae. It is native to central and western parts of the Amazon basin.^[2] It is migratory, moving in large groups into whitewater rivers to spawn, afterwards returning to blackwater and clearwater rivers, as well as flooded forests.^[3][4] It is important in fisheries^[4] and sometimes seen in the aquarium trade, but require a relatively large tank.^[3] It can reach a maximum standard length of 27.5 cm (10.8 in) and weight of 560 g (1.23 lb).^[2] It resembles the other members of the genus Semaprochilodus, where most species are silvery with orange-red fins and a striped tail.^[5] Adult S. insignis lack the dark flank spots that can be seen in adult S. taeniurus, but both species have these spots as juveniles.^[3]
