Adult G. loreto males establish nest sites, using small holes and crevices in the substratum, as a preparatory act leading to spawning, Males also utilise algae that they cut from the substrate to line the nests and to conceal the nest opening. Females subsequently travel to these nests prepared by the males, for egg deposition, typically in early morning at first appearance of sunlight. Females deposit eggs, that are negatively bouyant and about one millimeter in size to form a multilayer egg mass. Males guard and care for the eggs with four types of nest care behaviour: nest guarding, nest maintenance, detritus clearing in the nest vicinity, and periodic nest entering. The eggs hatch after ten or eleven days, and then the larvae are believed to enter the planktonic stage until they are sufficiently heavy to resettle by gravity onto the reef.
