“The garibaldi, Hypsypops rubicunda, is a California pomacentrid fish inhabiting the rocky subtidal between 0 and 25 m. Garibaldi feed almost exclusively on benthic organisms. Adults defend a territory which includes a shelter hole, grazing area, and for some males, a nest site. The territory is defended all year and against some other species as well as other garibaldi. The nest site is a small patch of red algae cultured by the male. The same site is used over a period of several years by the same male and probably by his successors. The female is allowed in the territory only to spawn; the eggs are guarded by the male. The young receive no parental care; they disperse into the plankton and settle out in shallow water. Age estimates from scales indicate that garibaldi assume adult coloration and mature at age 5 or 6 years and may live 13 or more years.”
