The Blue Pearl Shrimp ( Neocaridina palmata “Blue” ) is a distinct freshwater shrimp and a colour variation of the white pearl shrimp. Its colouring and body shape form a striking eye-catcher in the community tank. Their effect is particularly noticeable as a swarm.
The outfit shows an almost transparent and icy blue design. The light yellow eggs of the female form a beautiful contrast to this. The colour scheme changes during the development of the animals. While the still young shrimp have a whitish, grey-blue or faint blue colour, older animals reach an intensive blue tone. However, the strength of the colour depends on the acclimatisation period, the environment and the stability in the aquarium.
During breeding there are always specimens that are only pale blue in colour. Some even have reddish pigment spots.
The different sexes can be recognized by their body size. The males reach a size of 2 – 2.5 cm and are dainty. The females grow up to 3 – 3,5 cm and have a slightly fuller body shape. Another indication for the sex is the egg spot in the neck of the female after the onset of sexual maturity. That of the animals life expectancy loves with 2 years.
Blue Pearl shrimps belong to the undemanding and easy to keep aquatic animals. They are kept in a freshwater aquarium with a capacity of 20 litres or more. A larger community tank accommodates all inhabitants and is more stable. It offers the animals more variety as well as movement and retreat possibilities. The shrimp can give in to their strong urge to move and let off steam in the tank with their long legs. In addition, more space matches their desire to reproduce.
The furnishings should be attractive and practical at the same time, using plants and stones. It is important that the inhabitants find enough easily accessible hiding places. Especially suitable are plants with many, fiedrigen branches and leaves as well as accessible caves. However, fresh aquatic plants should not be placed in the aquarium immediately after purchase. This is because they can be contaminated with pesticides and harm the animals. It is advisable to water them outside the tank for a few days before the first insertion and then rinse them well.
The correct water temperature for an ideal community tank is a constant 20 – 28° Celsius. The water hardness is between 3° – 20° dGH and ideally 10° dGH. The ph-value is between 6.5 – 8. Blue Pearl shrimp are not very sensitive to water values. Special attention should be paid to the copper content of the water. Too high a level can damage the shrimp’s health.
The Blue Pearl shrimp is an omnivore and eats both plant and animal food. The special shrimp food consists mainly of vegetable matter. For a balanced protein balance, proteins can be given twice a week. Among the high-quality food forms are:
– Food in tablet form, as granules or flakes-
Live food and frozen food-
Algae powder (Spirulina )
– Nettle leaves-
Normal fish food
Another preference on the shrimp menu is the brown autumn leaves of the plants. They also prove to be useful cleaning agents in the aquarium. They love to destroy food remains, dead plant parts and graze off biofilms and algae growth. In this way they support hygiene in the tank and the health of the inhabitants.
If the attitude of the Blue Pearl shrimp is correct, the breeding is easy and they reproduce lively. The female becomes fertile every 5 – 6 weeks and carries between 20 – 30 eggs.
After fertilisation, the eggs hatch out fully developed young shrimp. They live immediately independent from their parents. During breeding there are always specimens that are only slightly blue in colour.
In order to preserve the original strain and the blue colour, the selection of the partner is important. Some even have reddish pigment spots. Crossbreeding tables help in planning possible crosses with other dwarf shrimp.
Like all dwarf shrimp, Blue Pearl shrimp have a peaceful and balanced nature. Aquarists make a good choice to build a lively and stable community aquarium.
The animals can live together in an aquarium tank for several generations. As designated group animals, the number should not be kept too small and should be quiet up to several hundred animals.
The socialisation is successful with mini fish, snails, mussels, crabs and freshwater crabs.
