One Fish, Two Fish, Red Fish, Blue Fish: Geography, Ecology, Sympatry, and Male Coloration in the Lake Malawi Cichlid Genus Labeotropheus (Perciformes: Cichlidae)

Figure 4

Frequency of nuptial color types at sympatric and allopatric populations of Labeotropheus. (a) L. fuelleborni. (b) L. trewavasae. While the proportions of nuptial colors displayed by L. fuelleborni remain relatively consistent whether found with or without L. trewavasae, note the marked increase of Red Dorsal coloration in populations of L. trewavasae sympatric with L. fuelleborni.
