Paretroplus gymnopreopercularis is a species of cichlid from the vicinity of the confluence of the Amboaboa and Mangarahara Rivers near Mandritsara in northern Madagascar.

[2] Until its official scientific description in 2008, it was temporarily known as the Paretroplus nov. sp.

[2] P. nourissati is found in the same region as P. gymnopreopercularis, but the latter appears to be restricted to deeper pools in the river (the former is from shallow, fast-flowing sections).

[2] The member of another cichlid genus, Ptychochromis insolitus, is also restricted to the region.

[3] 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.
