Convict Cichlids Benefit From Close Proximity To Another Species Of Cichlid Fish

Most studies reporting positive species interactions have focused on plants and sessile animals or have not been able to translate the hypothesised benefits into actual fitness gains.


Here, I demonstrate that brood survival of a fish, the convict cichlid, is higher when it has a Nicaragua cichlid territory in its close proximity than when it does not.


In other words, reproductive success of one cichlid species is facilitated by the presence of another.


The results may partly explain the immense success of the convict cichlid as an invasive species following introductions to new water bodies.
