Paretroplus gymnopreopercularis
Template:Short description Template:Speciesbox
Paretroplus gymnopreopercularis is a species of cichlid from the vicinity of the confluence of the Amboaboa and Mangarahara Rivers near Mandritsara in northern Madagascar.[1] Until its official scientific description in 2008, it was temporarily known as the Paretroplus nov. sp. "sofia". It is endangered because of habitat degradation, overfishing and invasive species.[2] Following the construction of a dam on the Mangarahara River, surveys have failed to relocate P. gymnopreopercularis in this river.[1]

Its habitat is shallow, clear rivers with a fast current and many areas of small waterfalls and riffles, normally with a rocky river bed, with many boulders, with sandy area mixed in. This species shows a preference for deeper, more isolated pools.[4]
