Fishes are an unusual group of organisms, in that males, rather than females, are the primary care givers in species that provide care.  While there exists a laundry list of possible explanations for this pattern, one still understudied hypothesis is that sexual selection acts in concert with natural selection to promote care.  I will share a series of studies in which I, and collaborators, have demonstrated that sexual selection does act on care in fishes.  However, the nature and implications of this selection pressure are not always as one would expect.
