several factors usually affect the fitness consequences of social decisions. We scrutinize the effects of group size and familiarity/relatedness on shoaling decisions in the Lake Tanganyika cichlid Lamprologus callipterus . Besides anecdotal remarks (Brichard, 1989; Konings, 1998), little is known about

Genetic data suggest that helpers in the cooperatively breeding Lake Tanganyika cichlid Neolamprologus pulcher occasionally migrate into nearby groups where they again become

species (Aiello & Wheeler, 1995; Navarrete et al., 2011; Tsuboi et al., 2015; Liao et al., 2016a). Consistent with the ETH and the “energy trade-off hypothesis”, relative brain size exhibits a negative correlation with gut size in Lake Tanganyika cichlids, anurans and primates (Aiello & Wheeler, 1995

Variation in the duration that males have held bowers may also help to explain why male standard length and colour, two common measures of

specialists co-exist with generalists. As an example, let us examine the new ecological model as it relates to three Lake Tanganyika cichlids: the generalist Lobochilotes labiatus, the 252 stenotopic (HORI, 1991) Perissodus paradoxus, and the eurytopic spe- cialist Petrochromis polyodon (fig. 3).
