The two-coloured Red Rili shrimp, which belongs to the Neocaridina family, is an eye-catcher in every aquarium: its pattern consists of a strong red and transparent. The pattern looks like this: Usually the head and tail fan are dyed red, while the middle of the shrimp’s body remains transparent.
This colour contrast makes the red areas shine especially intensely. By the way, the breeding of this colour form originally started in Taiwan. Each Red Rili shrimp has an individual pattern and can therefore be easily recognized. Sometimes the red is a uniform surface, sometimes it appears in a pied form. Red Rili shrimp grow up to three centimetres in size.
Red Rili shrimp are very robust and have few demands on their home. They are therefore ideal for shrimp or aquarium beginners. The small red transparent shrimp feels most comfortable in medium-hard to hard water. The pH value of the water can be between six and eight. The aquarium should have a capacity of at least 20 litres and be filled with many plants.
Care should be taken to ensure that it offers sufficient hiding places. Mosses such as java moss or Christmas moss and also nymph are very suitable for planting in the aquarium. In general, 60 to 80 percent of the ground in the aquarium should be planted. Moss balls offer the small shrimp good grazing opportunities. Stones, woods and brown foliage offer the shrimp further good opportunities for retreat.
The bottom of the aquarium should be covered with shrimp gravel or natural gravel. By the way, Red Rili shrimps shine especially beautifully in front of a dark bottom. Red Rili shrimp are group animals and should therefore never be kept alone. Groups of 10 to 20 animals are ideal. Other peaceful roommates like mussels, crabs or peaceful fish are no problem. By the way, a heater is not needed in the aquarium.
The Red Rili shrimps are omnivores. Ideally, they receive protein food once or twice a week. Otherwise they can be fed with vegetable food. To raise the young shrimp, they should be placed on a dust-feed. Otherwise, the shrimp can also be fed with natural food. This can be, for example, leaves, alder cones or nettles. Dead plant parts, biofilm and microorganisms, which usually occur in the aquarium anyway, are also used by the shrimp.
The breeding of the Red Rili shrimp is also quite simple. By the way, this shrimp is a pure breeding form. It does not occur in nature in this way. As with all Neocaridina shrimp species, the young shrimp grow up quickly. Both male and female shrimp are needed for breeding. The female animals are usually slightly larger than the males. However, the sex of the animals is not always clear, so you should work with a breeding stock of at least ten animals. If the water quality and food are right, the shrimp will reproduce almost by themselves. For fertilisation, the female sheds its skin and thus releases the eggs.
After fertilizing the eggs, the female keeps them with her and supplies them with nutrients and oxygen. After a gestation period of about four weeks, females give birth to between 20 and 35 young. These are between one and two millimetres in size. The survival chances of the young animals are good.
The greatest danger is posed by other roommates in the aquarium, who might see the young animals as a welcome change on the menu. Therefore a species tank is better suited for breeding than an aquarium with other animals. The adult animals pose no threat to the young animals. By the way, the beautiful colouring of the shrimps will only become visible in the young animals after a few weeks.
Since the Red Rili shrimp are very peaceful contemporaries, they can be socialized optimally. They like to share the aquarium with crabs, other dwarf shrimp, crabs, snails or mussels.
Only with dwarf crabs is caution necessary, as they catch and eat the small shrimp every now and then. Smaller fish are no problem as long as they are not too curious or voracious.
