Correlated aggressive and brooding behavior patterns in Tilapia (Pisces, Cichlidae)

SummaryCorrelations between the behavior patterns “fanning the eggs”, “digging into the substrate” and “attacking of conspecifics” are shown in two Tilapia species. Sexual differences in these behaviors could not be demonstrated in the monomorphic T. guineensis, but they were shown in the dimorphic T. mariae.The results could be used to predict the behavior of a fish in a second, naturally defined unit by knowing the result of only one behavior pattern in the first unit.
