底栖卵块回收参加了由雄性的Gramma洛雷托，一个物种，据报道是一个mouthbroader巢。巢由小的圆柱形洞，狭窄的裂缝，或在坚硬的底层小凹陷。卵被沉积在一团松散的缠绕在一起的海藻上，海藻附着在巢穴的内壁上，形成一层到三层的卵。雄鸟表现出不同类型的护巢行为。牠们会在巢口前盘旋或停留，并追逐接近牠们巢的其他鱼类;在巢口建造藻类垫;将藻类碎片带进巢内;以及清除巢内的淤泥。没有证据支持G.洛雷托是一个口栖动物。从田间收集的卵在实验室中在23-27 ℃的温度下饲养，从桑椹胚期到孵化大约需要10-11天。初孵仔鱼眼有色素，颌发达，卵黄量少，全长2.9- 3.8mm。
Demersal egg masses were recovered from nests attended by males of Gramma loreto, a species that has been reported to be a mouthbrooder. Nests consisted of small cylindrical holes, narrow crevices, or small depressions in hard substratum. Eggs were deposited on a loose clump of entangling algae that clung to the inside wall of the nest and formed a plain sheet of one to three layers of eggs. Males showed various types of nest care behavior. They hovered in front of or remained at their nest entrance and chased other fish species that approached their nest; constructed an algal mat at the nest entrance; carried pieces of algae into nest interior; and removed silt from the inside of the nest. There was no evidence to support the hypothesis that G. loreto is a mouthbrooder. Eggs collected from the field were reared in the laboratory at the temperature of 23-27 C and required about 10-11 days from morula stage to hatching. The newly hatched larvae had pigmented eyes, well-developed jaws, a small amount of yolk, and were 2.9-3.8 mm in total length.
