The Flash Pleco originates from the Rio Alejandro in Peru. The "flash" is narrow bands of white or yellow against a black background. It is also sometimes called the Flash Peckoltia. Flash Plecos must have wood in their tank, which they enjoy eating. They prefer strong water flow, sand and hiding places or caves. Flash Plecos are not aggressive.
Adult coloring becomes more yellow and lines can become interrupted by the underlying darker body color. Males are slightly larger than females and have longer pectoral fins. Breeding is extremely difficult and Flash Plecos are obtained commercially in the wild in Peru.
