Red Cherry Shrimp are one of the simplest creatures to breed in an aquarium.

There are 3 main things to consider when breeding Red Cherry Shrimp, inducing your shrimp to breed, carrying of the eggs, and raising the fry.

If all those considerations are favorable, your Red Cherry Shrimp will flourish and their population will quickly increase.





Inducing.

To induce your Red Cherry Shrimp to breed simply requires a pair of sexed shrimp, stable water parameters, and a ready supply of food source.

Male RCS are considerably smaller and much less colorful than females, with the females frequently having a yellow "saddle" which are the eggs developing in her ovaries.

When these shrimp are juveniles it is almost impossible to determine their sex, however one obvious distinction is that females generally have a rounder and and more elongated tail section.


Water Parameters.

Should be kept as stable as possible and within acceptable ranges.

The pH of the water should fall between 6.5-8.0. and the temperature should be maintained between 70-80°F.

The water hardness is not considered important as long as it is neither extremely hard nor soft.

Food.

When they are breeding, shrimp require a consistent food source.

If the population of your tank is small to moderate, frequently the naturally occurring algae in the tank ill be an adequate source of food.

If supplemental feeding is required, then commercially prepared fish foods and blanched vegetables are also appropriate food sources.

Mating.

When both male and female shrimp are sexually mature (3-6 months old) and those other requirements are met they will breed, which occurs immediately after a female molts, which is the process of shedding the existing exoskeleton.

Molting allows the shrimp to continue growing and to re-grow a new exoskeleton which now fits the larger body.

During this time, the female shrimp is extremely vulnerable and she will hide wherever she feels safe.

At that point, she will release pheromones (sexual hormones) which have the effect of luring the male to her secret location and encouraging him to mate with her.

When the male eventually finds the female they will breed, with the male depositing his sperm into the female. When the sperm has been deposited, the female then passes the eggs threw it whilst on their way to the underside of her tail, where they will remain until hatched.

These eggs are then constantly fanned by the female's pleopods (swimming legs) to keep them both clean and oxygenated.

Once these 20-30 eggs hatch, the juvenile's are tiny replicas of their adult counterparts. They have no larval stages  and the young shrimp will eat the same available foods as the adults, tending to use the nippers on their front legs to tear off small edible chunks of the food.

Raising Fry.

When raising young RCS it is important to have no predators in the tank.

Few if any, fish, can resist gulping a tiny shrimp as a midday snack and if breeding shrimp in a tank where there are predators then the only way to ensure young shrimp will reach maturity is to provide numerous hiding places but even doing this will not ensure success.

The inclusion of live Christmas Moss, Java Moss and any other slow growing aquatic plant in your tank will help increase the chance of your fry growing into adult specimens, with these slow growing plants typically harboring micro fauna and various other food sources for your young shrimp.

Whilst not essential for successful breeding, these plants will certainly lead to healthier, faster growing shrimp.

There you have it, provided the 3 variables important to breeding shrimp are understood, then establishing a happy, healthy breeding colony can be easy, fun and very rewarding.
