In most cases, regardless of the breeding strategy, the female is more highly involved with care of the eggs and fry, whilst the male defends a territory from predators. The sex of the fry is affected by the water conditions: In all species where it has been studied warmer water results in more males and in some species more acidic water (lower pH) also results in more males.Römer, U., and W.
