Peckoltia Pulcher Biography
The Butterfly pleco was scientifically described by Kner in 1854 and given the name Ancistrus brachyurus. It has been moved around quite a bit among different genera and you might therefore find the names Zonancistrus brachyurus or Peckoltia brachyura in some sources. Today, the Butterfly pleco is considered a part of the genus Dekeyseria and its scientific name is therefore Dekeyseria brachyura. Some shops sell Dekeyseria brachyura under the name Peckoltia pulcher.
