Life Cycle
Male saddle blennies defend small territories in rubble and sand habitat. They court passing conspecific females which, when receptive, follow the male to a crevice where they deposit their eggs. Females have home ranges, rather than territories and do not participate in the protection or care of the eggs. Eggs are highly susceptible to predation by the Bluehead Wrasse (Thalassoma bifasciatum). Males may co-defend a territory with Beaugregory Damselfish (Stegastes leucostictus) males. The species appears to benefit from this association because the larger male Beaugregory Damselfish plays a larger role in defending against the Bluehead Wrasse
