Intrasexual selection on body coloration is thought
to play an important role in the evolution of colour polymorphism,
but its physiological underpinnings have received limited
attention. In the colour polymorphic cichlid Neochromis
omnicaeruleus, three fully sympatric female colour morphs—
a plain morph (P) and two conspicuously coloured blotched
morphs, black-and-white blotched (WB) and orange blotched
(OB)—differ in agonistic behaviour. We compared routine
metabolic rate (when females were housed in social isolation),
short-term energetic costs of interacting with a same-colour
rival housed in an adjacent transparent chamber and oxidative
stress between the three female colour morphs. WB females
had a lower routine metabolic rate compared with the other
colour morphs. WB females also had a lower active metabolic
rate during inter-female interactions than OB females, while
OB females used more oxygen per unit aggressive act than the
other two colour morphs. However, there were no consistent
differences in oxidative stress between the three morphs.
Concerted divergence in colour, behaviour and metabolism
might contribute to the evolution of these polymorphisms in
sympatry.
