Orange Shrimp

Appearance

Orange shrimps have an intense bright orange to dark orange colour. The older the animals become, the more pronounced their colour. As a rule, the females are more intensely coloured. Newborns are initially more or less colourless until they begin to turn orange at the age of three months. As the shrimp belong to the dwarf shrimp family, they only grow to an average size of 2 to 2.5 cm. They also have black and large stem eyes.

There are four long and two short antennae on the head. The long ones exceed the physical dimensions of the orange shrimp. The food feelers in the mouth area are followed by four walking legs including scissors, which are responsible for bringing the food into the mouth. Five pairs of floating legs on the abdomen are used for swimming. At the end of the back follows a fanned fin.

Attitude

The shrimps should be kept in an aquarium with at least 25 litres of water. Male orange shrimp in particular require little space, provided the tank is sensibly planted. As the animals often move on the ground, a substrate as fine as possible is advantageous. Coarse gravel, on the other hand, would tend to be very disturbing. Recommended are for example Fluval Stratum, fine aquarium sand, shrimp gravel, chinchilla sand or nano substrate.

With lava stones, shrimp trunks, perforated rocks, clay tubes, ceramic objects or plants such as grass rush, java fern, nixwort or hornwort, one ideally creates retreat possibilities. The finer the leaves are, the more suitable they are for the aquarium. A hamburger mat filter or a sponge filter are useful, as most other filters could inadvertently cause the death of baby shrimp.

The animals hardly need any light. They can survive well at temperatures between 15 degrees Celsius and 25 degrees Celsius. At least a third of the water should be changed every two weeks.

Chuck

Plants that have already died off, leaves or the tiniest of creatures can be used as food for the orange shrimp. The animal protein can be covered with fish food flakes. Dried herbs or leaves such as dandelion, apple tree leaves, hazelnut leaves, walnut leaves, stinging nettle or birch leaves offer a balanced supplement. Boiling water should be poured over the leaf mixture before feeding, which should then be cooled and rinsed several times.

Sea almond leaves are praised as particularly healthy, as they have an antibacterial and fungicidal effect. They also support the healing process in case of inflammations. One to three sea almond leaves should be added to 100 litres of water. If the leaves have not been consumed after three weeks at the latest, it is better to remove them because of the loss of the ingredients.

Breeding

After about three months the shrimps can reproduce. Only at this point can males and females be distinguished from each other. The females mainly become thicker and rounder. The ovaries are located in the nape of the neck, where the eggs are produced in a light spawning area. After the female has moulted and released pheromones, the eggs are fertilised. The males swim conspicuously active and stick their semen to the genital opening. Once the female has transported the eggs through the semen, she attaches the eggs between the swimming legs.

The initially white eggs change their appearance until they are transparent. Within four weeks, the mother female rearranges them again and again and supplies them with fresh water until the baby shrimp hatch. If you have orange shrimp available, breeding them is therefore not a problem in principle, as they behave according to their nature and therefore reproduce independently. Depending on the desired colour tone, there is the possibility of selection.

Association

As a subspecies of the dwarf shrimp, there are no problems if the orange shrimp are used to keep fan shrimp, mussels and snails at the same time. The latter are often also cleaned by the shrimp. An obstacle, however, is posed by the large-armed shrimp, the crayfish and the crabs.

If you want to keep various dwarf shrimp, you have to take into account that the habitat conditions are equivalent for all of them. If the dwarf shrimp are kept in the aquarium together with fish, the fish should originate from the same continent because of the geographical conditions.
