The Mini Japopnica shrimps are rather inconspicuous in appearance. At first sight they resemble the Amano shrimp. Their body is slightly transparent and they have a rather bluish body colour. However, Mini Japonica shrimp lack the typical blue dot rows that are typical for Amano shrimp. They are also much smaller in direct comparison. Amano shrimp can also grow up to 5cm in size. Mini Japonica shrimp, however, grow to a maximum size of 3cm. It is mainly the females that can reach such sizes. Males, on the other hand, are considerably smaller at just under 1.5cm to 2cm.
Mini Japonica shrimp are relatively undemanding in terms of their environment. They do well in warm aquariums with an average temperature of 25°C. No special water quality is required for keeping them and the animals can even overlook this if the aquarium is not polished to a high gloss every week. Due to their small body size the animals are also content with the smaller habitat of a 12l aquarium if kept alone. However, it is recommended to keep the shrimp in a larger aquarium to be able to keep them in larger groups.
In order for the shrimp to feel really comfortable, aquarium owners should offer the animals many places of retreat in the aquarium. On a soft, sandy ground, hollow stones, wood and bamboo canes should not be missing. Mangrove roots or tall grasses are also frequently visited by Mini Japonica shrimp. The small animals like to hide there when it gets too restless in the aquarium. Young animals, on the other hand, tend to use these hiding places to protect themselves from possible predators.
The Mini Japonica shrimp do not shy away from daylight. You can watch them crawl across the floor and search the sand shortly after they have entered the aquarium. Only when they are restless do they flee quickly.
Mini Japonica is one of the all-purpose shrimps. They can feed themselves by eating microorganisms or small algae from the bottom of the aquarium. But you can also feed them normal shrimp food such as chinchilla pellets. The animals like brown autumn sounds and small pieces of vegetables just as much. As a small delicacy it is sufficient in the summer months to briefly brew a few nettle leaves and then add them to the aquarium.
Aquarium owners should only refrain from animal food such as frozen food. The food can cause the shrimp to moult, which can lead to the loss of limbs.
If you would like to breed your own shrimp, but have little experience with them, Mini Japonica shrimp is a good choice. The animals belong to the specialized reproduction type, in which the larvae in the eggs go through several cycles until they are fully mature. The female keeps the eggs in her breeding chamber between her legs for about 4 weeks before releasing the young. Immediately after that, the female produces new eggs again, so that she can give birth to between 20 and 40 young shrimp several times a year.
As the larvae develop exclusively in the eggs, multiple tanks with different types of water are not required for breeding. This makes the breeding of Mini Japonica shrimp comparatively easy. The only problem is the number of young that can be born per clutch. If prospective breeders are not careful, an aquarium can be overpopulated with young shrimp in a very short time. It is therefore advisable to keep the group small. This works well if you place females and males in different aquariums and only bring them together if you really want to have offspring. Because of their different body sizes, the sexes are also easy to distinguish, which makes it easy to separate them.
Mini Japonica shrimp like to be part of a larger group. Therefore you should bring the animals together with about 20 to 30 of their conspecifics. The socialization also works with snails or small catfish without any problems. If you want to keep the animals with smaller fish in the same aquarium, you should pay close attention to how the fish behave. Possibly they see the small shrimps as prey and will hunt them if you are not careful.
