As the name suggests, the green shrimp is naturally green in colour.

However, the colour can only appear on some parts of the body or on the whole body in different shades of green. However, due to the quality of the water or as a result of changes in mood, the green shrimp can also take on other colours, so that this shrimp species is not always immediately recognisable and identifiable as such.

The colours seen so far vary between blue, orange and brown. In addition, some representatives of this species have a colour-contrasting backstroke. The body shape of the animals is relatively slim and flat. However, this can also vary between individuals.

In the aquarium, green shrimps live for about two to three years. The shrimp species is considered suitable for beginners and is a real eye-catcher in the aquarium due to its many colours and colour changes. The keeping is relatively uncomplicated. The green shrimp is a very active and sociable animal that only feels really comfortable in a group.

Ideally, at least ten to twenty shrimp should be kept together, then the extensive social behaviour of the green shrimp can really unfold.

The aquarium should not fall below a volume of 20 litres so that the animals have enough space to move around. When keeping the green shrimp, a water temperature of 25 to 30 degrees Celsius and a pH value of 7 is considered optimal. For the shrimp to feel comfortable, they also need lush planting and numerous hiding places and retreats.

The green shrimp feeds mainly on leaves and algae that settle on roots and stones. An aquarium for this shrimp species should therefore be well stocked with plants and leaves. Smaller insect larvae are also on the menu from time to time. In community aquariums the green shrimp also feed on the food leftovers of other animals. For this reason, the green shrimp can certainly be described as omnivorous.

Additional feeding is usually not absolutely necessary if the shrimp are kept in a species-appropriate manner. If you still want to feed them, you can add shrimp food to the aquarium. A protein food additionally covers the crustaceans’ needs. The tiny juveniles require particularly fine food. It is therefore recommended to allow bottom mulm in breeding tanks. If you would like to feed them, you should provide the young shrimp with powdered food.


Under good husbandry conditions, the green shrimp usually reproduces independently. A female shrimp can become pregnant every two to four months and give birth to 50 to 80 young each time. The gestation period is about four weeks. The green shrimp give birth to their young when they are fully developed. Due to their small size, the small animals are more reminiscent of larvae than shrimp in the first few weeks.

It is important for breeders to install a shrimp filter in the aquarium to protect the floating young animals from being sucked in. Fish should not be kept together with young green shrimp, as they would regard the small shrimp as food. Very fine food is needed to feed the small green shrimp. It is therefore advisable not to keep the water 100% clean, but to allow some algae and bottom muck. Dust food is also a suitable food for the young shrimp.


Green shrimps are very active. They are very peaceful towards their conspecifics and fish. However, due to their small size, the young shrimp are particularly vulnerable to predators. Only peaceful animals such as other shrimp species should therefore be considered for socialisation. Make sure that any cross-breeding among the shrimp species can be ruled out. Snails, crabs and mussels are also good company for green shrimp. If you want to keep the shrimp together with fish, you should choose small and peaceful animals such as the mosquito rasbora, the luminous-eyed rasbora, a strawberry rasbora, a bitterling rasbora or a guinea fowl rasbora.
