ORANGE RILI SHRIMP selectively bred from Orange Neocaridina Shrimp for their rili pattern - a striking red and white coloration, with the white parts often appearing translucent. Like many other Neocaridina shrimps, Red Rili can live in wide range of water parameters, as long as there will not be sudden change to their enviroment. They are very popular for planted tanks and community tanks, and many people use them in large aquariums for waste management and algae control. A colony of these shrimp works as a very effective cleaning crew for your aquarium, cleaning up algae and waste.
We generally ship young adult shrimp that are already of breeding age, that are about 1/2 inch to 3/4 inch in length. Some of the younger shrimp have not reached their full potential yet and will grow into a bright orange color as long as they are comfortable in the tank. Lower intensity lighting and dark substrate also helps them achieve the brightest orange.
 
Like many other Neocaridina Freshware shrimps, Orange Rili Shrimps shares the same similar behavior when it come to caring, feeding and breeding:
Caring
Orange Rili Shrimps are tolerant to a fairly wide range of water parameters, making them excellent for pairing with other species. As long as the shrimp are acclimated properly to your chosen parameters and are not subjected to extreme changes in temperature or acidity, they are adaptable and resilient. They will tolerate soft or hard water. The ideal water parameters are 70°-85° F with 7 to 7.5 pH. However, as mentioned, you may keep them outside of these parameters as long as the shrimp are protected from extreme or frequent fluctuations. Stabilization is the key to successfully keeping and growing your shrimps colony

Feeding
Orange Rili Shrimps will accept a wide variety of foods, and in planted tanks may be able to survive off of scavenged biofilm and algae. A colony of these shrimp works as a very effective cleaning crew for your aquarium, cleaning up algae and waste.  They are very popular for planted tanks and community tanks, and many people use them in large aquariums for waste management and algae control. Only if there are too many shrimps in your tank for the available algae and biofilm, or not enough plants to produce it, you can supplement their diet with algae tablets, blanched vegetables, or any other shrimp food.
Also, keep in mind, it is very important not to overfeed your shrimp, as this can be harmful to their health and even result in death. Increased waste from overfeeding your shrimp can impact your nitrogen cycle and increase tank maintenance, as well as harm your tank’s inhabitants.
Feeding shrimp once per day is usually enough, especially if biofilm and algae are available. If shrimp are not responding to food, or leave food uneaten for more than a day, remove the food and decrease feeding. Especially in mature planted tanks, your shrimp may not need supplemental feeding very often.

Breeding
Orange Rili Shrimps are eager breeders given comfortable water parameters and a sufficient food source. Once the shrimp reach maturity, and if there are males and females present, they should breed naturally and frequently. It is recommended to purchase 8-10 shrimps to ensure that there are enough male-female pairs for successful breeding.Generally speaking, once the shrimps are fully- grown, male shrimps are generally smaller, lighter in color than females, and exhibit lower color grades. Female shrimp have slightly larger tails and display a “saddle” formation on the upper body, behind the head, where eggs are stored before fertilization. When female shrimp are “berried”, or have eggs ready for fertilization, the saddle shape will appear more prominent. Once ready for mating, female shrimps will molt and release pheromones that the male shrimp respond to with frenzy. After the eggs are fertilized, they will be moving down to the female’s belly where the berried female will fan the eggs for about 4 weeks of gestational period.  After about 4 weeks, eggs will hatch into little shrimplets. The shrimp fry will feed from the same food sources as their parents, and will molt frequently during their early life stages. Leave molted shells in the tank, as the shrimp fry will consume them for extra minerals like calcium that will help their growth. Keep in mind that if you are keeping shrimp with other species of fish, or possibly aggressive shrimp species, this may affect reproduction. If the shrimp feel threatened or don’t have places in your tank to hide they may not breed.
