- shrimp riley carbon;
- Orange Riley;
- Red Riley;
- Yellow Riley.
The selection is based on a strict selection of colors, which combines the ratio of colored and transparent parts of the shrimp. The more transparent parts the shrimp has, the higher it is in class. Breeders try to get the perfect look of Riley's shrimp: the belly is completely transparent, without color spots, and the cephalothorax is colored. Another direction - the shrimp is completely transparent, and on the sides - two symmetrical spots of red or orange.
Riley with its unpretentiousness in care attracts a huge number of aquarists. This amazing creature appeared in Russia in the summer of 2004, and aquarium shrimp was widely used in 2010.
Riley prawns are available in the following variations:
- burgundy or red cephalothorax and tail;
- burgundy or red cephalothorax and tail, and the body of the shrimp is transparent blue;

- yellow cephalothorax and tail;
- black cephalothorax and tail; body transparent or blue.
Description
Classic Riley is very beautiful. Their body is completely transparent, the tail and cephalothorax are yellow, bright red, black or orange. On the belly there is often a speck that corresponds to the main dominant color. Females reach 2.5 cm in length, and males 2 cm.
Shrimp Riley: Contents
Riley, like other shrimps, prefer pure filtered water, which should be free of nitrites, nitrates, ammonia and ammonium.
Filtering water is best done with a biofilter. The water in the aquarium must be changed every week. Copper compounds should not fall into it, otherwise the shrimp will die quickly. The life span of an aquarium shrimp is approximately 2-3 years.
Riley prefer rich vegetation and soft moss bedding. Dark soil such as gravel is ideal. If there is no suitable soil, then on the existing one you can put almond leaves, which have an exquisite chocolate color.
It is advisable to purchase an aquarium with a volume of more than 10 liters, the water temperature should be about 20–28 degrees, pH from 6.0 to 8.0. Shrimps mainly live in small groups of 15–20 individuals. Riley get along well with friendly small fish.
Nutrition
Riley shrimps feed on algae, dead plants, fish food debris, silt. Riley can be fed with special food, for example Bio Max, spinach or nettle leaves, which are pre-poured with boiling water. Shrimps are fed in small portions, they should not overeat.
It is recommended to give shrimp food once a day. Once a week you can not feed. This does not harm them, so they cleanse their body. Riley can be kept with other species.
Breeding
Riley prawns interbreed with each other, as well as with other species. After several generations, the original pale gray color prevails in the shrimp color. If all conditions are met, then the shrimp themselves actively reproduce. The gestation period is 3-4 weeks. First, females hatched eggs - this can be seen by the appeared bright spot on the back of the shrimp.
Further, under the tail of the eggs, an incubation period passes. If the eggs are visible in the eggs, then the female will soon discard the babies. The eggs are yellow. On average, the female produces offspring of 30–40 fully formed small shrimps, which are an exact copy of their parents and are ready for independent existence.
Small shrimp do not require separate care and nutrition. The sizes of the born individuals are 1–2 mm. After 4-5 months, Riley's shrimp become sexually mature.
Compared to the female, the male is thin and small in size. Riley females have a more saturated color, unlike males.
The survival of the offspring is very large, so Riley is great for beginner aquarists. The environment, and in particular the soil, greatly affects the color of the shrimp. Riley will have a bright color if the soil is hard.
Shrimps of this species are very entertaining creatures - they are curious and friendly. Throughout the day, they swim around the aquarium, cleaning plants and collecting leftover food.
In general, this is a rather interesting and beautiful view of shrimp. Riley (aquarium shrimp) will be a great choice for those who are just starting to be interested in aquariums.
