Red Head Cichlid, Quetzal Cichlid
Distribution: The Río Usumacinta drainage within Mexico, Belise, and Guatemala. The locale that I’m currently keeping is Mexican.
Etymology: Melanurus, Presumed Melanos ouro, Greek for black tail, refering to the caudal band on the holotype for P. malanurus, aka the Black Tailed Cichlid.
Recent reclassification has designated synspilum/synpilus as junior synonyms for melanurus, signifying that the cichlid initially described as P. melanurus and those known P. synspilum/synspilus are locale-distinct phenotypic expressions of the same species.
