Synopsis

Most Central American cichlids spawn in caves. There has been considerable work documenting where cichlids lay their eggs, and how this may be beneficial to the offspring. However, it has yet to be determined which physical factors of a spawning site influence choice. This study examines the importance of light intensity, potential position of eggs, and number of entrances on spawning site selection in the convict cichlid, Cichlasoma nigrofasciatum. The results suggest that cave light intensity and entrance number determine spawning site selection in this species. Both factors are important in concealing the brood and offering it maximum protection from predators.
