Breeding
Breeding red cherry shrimp is as easy as putting an adult male and female together in an aquarium. You can observe the eggs 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 moulting, 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, the female lays her eggs and affixes them to her swimmerettes.
They have 20–30 eggs, which take 2–3 weeks to hatch. The eggs are green or yellow, depending on the colour 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 shrimplets within can be observed. When the young hatch, they are tiny (~1 mm) copies of the adults. They have no planktonic larval stage. They spend their first few days of life hiding among plants, where they are almost invisible, nibbling on the biofilm on the plants. They then emerge and graze on algae on tank surfaces and ornaments.

Famous quotes containing the word breeding:
“The breeding we give young people is ordinarily but an additional self-love, by which we make them have a better opinion of themselves.”
—François, Duc De La Rochefoucauld (1613–1680)
“The Fashionable World is grown free and easie; our Manners sit more loose upon us: Nothing is so modish as an agreeable Negligence. In a word, Good Breeding shows it self most, where to an ordinary Eye it appears the least.”
—Joseph Addison (1672–1719)
“Civility, which is a disposition to accommodate and oblige others, is essentially the same in every country; but good breeding, as it is called, which is the manner of exerting that disposition, is different in almost every country, and merely local; and every man of sense imitates and conforms to that local good breeding of the place which he is at.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
