Red Rili Shrimp (Neocaridina davidi var)

Red Rili Shrimp are peaceful and sociable freshwater shrimp. These shrimp are highly adaptable creatures and can live in almost any freshwater aquarium with a wide range of water parameters. A colony of these shrimp works as a very effective cleaning crew for your aquarium, cleaning up algae and waste. Red Rilis are very popular for planted tanks and community aquariums because they are very active and breed very quickly.

You can keep Red Rili Shrimp with different shrimp species in the same tank as well as smallish non-aggressive peaceful fish.

Red Rili Shrimp feature a prominent red and white colouration, with the white parts often appearing transparent. They have a diverse degree of transparent areas, from very little red to mostly red with clear patches. However, their standard colour usually consists of red on the head and tail with a clear body. These shrimp typically have different markings.

Natural Habitat

Red Rilis originate from Taiwan in Southeast Asia. Their natural habitat usually consists of densely planted freshwater rivers, ponds, streams and lakes with sandy or rocky substrate surrounded by forests. The waters are often slow-flowing, and there is usually little to no tannins or staining in the water.

What to feed the Red Rili Shrimp

Red Rili Shrimp will accept various foods, and in planted aquariums, they may survive off scavenged biofilm and algae. If you have too many shrimp in your tank for the available biofilm and algae or not enough plants to produce it, you can supplement their diet with algae wafers, blanched vegetables, or other shrimp food.

It is essential 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 increase tank maintenance and affect your nitrogen cycle, as well as harm your tank's inhabitants.

Feeding your shrimp once daily is usually enough, especially if algae and biofilm are available. If your shrimp are not responding to food or are leaving food uneaten for more than a day, make sure you remove this and decrease feeding.

How to Sex the Red Rili Shrimp

It is relatively straightforward to differentiate male from female Red Rili Shrimp. The males are much smaller and usually less colourful than the female, and because they do not need to carry eggs, their tails are generally narrower. In contrast, the female is larger and usually displays a more elaborate, opaque colouration.

How to Breed the Red Rili Shrimp

Breeding Red Rili Shrimp is relatively easy. These shrimp reach sexual maturity when they get to about 4 to 6 months old. All you need is a small colony of around ten individuals; this will ensure you have both males and females.

To encourage breeding, condition your shrimp with high-quality foods and keep your water quality reasonable by performing regular water changes. If your female shrimp are healthy, they should be pregnant most of the time.

Female shrimp will carry their eggs between their back legs, regularly splashing fresh water over them and picking off any rotten eggs to prevent fungus. The eggs will usually hatch around 28 to 30 days later.

The babies look like miniature copies of the adults, and there is no need to remove them to a separate tank. Make sure there's plenty of food for them, and they should develop and colour up quickly.
