Blue footed shrimps / Caridina caerulea / Blue leg poso


The blue footed shrimp comes from Indonesia. There mainly from the Indonesian island Sulawesi. This form of shrimp is scientifically called Caridina caerulea. It has a very interesting pattern and is therefore very popular. It is a lot of fun to learn about this shrimp shape and to keep it. The name blue-foot probably comes from the fact that these exotic aquatic animals very often have blue coloured legs. But not only the legs can be blue in this shrimp form, but also the tail fan and/or the rostrum. It is also noticeable that all shrimp of this species often have antennae coloured in a red tone. When the animals are active on the bottom, they do not discolour and are therefore always easy to see.


The blue-footed shrimp is quite easy to keep, which is partly due to its size of up to 3.5 cm. The shrimp, which is often matt-transparent, should definitely be kept in a group. The tank should be a bit bigger, because the water dwellers love the free hit. An aquarium from 20 litres is usually recommended. The water temperature should preferably be between 26 and 30 degrees. Unlike many other shrimp species, the blue-footed shrimp are quite active. But you do need good planting to be able to retreat from time to time.

The aquarium should best be equipped with an aerator. Because with it you can expel CO2 and ensure that the PH value is perfect for the shrimp. Some aquarists also like to use an oxidizer. The substrate should be rather neutral for the shrimp. The heater itself does not need to have quite as much watts. 25-75 watts are absolutely sufficient. At 75 watts you can of course ensure that the heater does not have to heat for too long to reach a comfortable temperature for the shrimp. As the animals are very sensitive, the purchase of a programmable thermometer is also recommended. This triggers an alarm if the temperature drops, thus endangering the welfare of the shrimp.

In addition to algae and mulm, blue-footed shrimps also love normal fish food. There should always be enough food available so that all shrimp in the group have enough to eat. It would also be very recommendable to provide food tablets, which are also very easy to handle.


The blue-footed shrimp prefer to reproduce in fresh water. The eggs will produce young after 3-4 weeks. They can feed themselves immediately, because they are fully developed juvenile shrimp. Until the young shrimp hatch, they are transported between the mother’s legs. Therefore, females are very easy to distinguish from males. The juveniles do not need to be placed in an extra tank, but can stay with the other shrimp. The shrimp are very easy to keep and have a life expectancy of 2 years.


Society loves this shrimp variety. Since the blue-footed shrimp are very peaceful animals, they can be kept with all other aquarium inhabitants who do not mind the shrimp and do not attack them. In this case, other shrimp, fish and also crabs can be kept. In this case, however, the plants in the aquarium should not be forgotten, so that the blue-footed shrimp also have a chance to hide if they feel like it.
