Neocaridina fire/red shrimp couple and their baby shrimps (shrimplets)

N. davidi shrimp reach sexual maturity at approximately two months of age.Breeding only requires a sexed pair of shrimp, stable water parameters, and a food source. Eggs may be observed developing in the female's ovaries as a green or yellow triangular "saddle" marking on her back. When she is ready to lay the eggs, which occurs after molting, she releases pheromones into the water to signal her availability to males. The male shrimp in the tank will often become agitated, swimming very actively about as they search for the source of the pheromones. After a brief mating process, during which the male deposits sperm onto the female's body, the female lays her eggs and affixes them to her swimmerettes, or pleopods. The eggs are not fertilized within the female; they are fertilized as they pass from the ovaries to the outside of the body. Therefore, it is certain that any shrimp carrying eggs has mated. Females produce between 20–30 eggs at a time, which take 2–3 weeks to hatch.[29] The eggs are green or yellow, depending on the color of the saddle. They turn darker and darker until the young shrimp hatch after about three weeks. As the eggs near the end stages of growth, tiny dark eye spots of the developing shrimp within can be observed. When the young hatch, they are tiny (roughly 1mm) copies of the adults, as N. davidi does not have a larval stage. #neocaridinashrimp #neocaridina #redshrimp #fireshrimp #aquarium #cherryshrimp #shrimp
