Caridina shrimps are known for their beautiful colors and are often considered the more extravagant variety compared to Neocaridina shrimps. With intense colors and complex patterns, these shrimp are a feast for the eyes.

However, the splendor of Caridina shrimp also comes with greater responsibility, as they require more demanding care and attention. To stay in optimal condition, Caridina shrimp have specific requirements with regard to both the water values ​​and the design of their living environment. Originally, Caridina shrimps are found in Asia, mainly in small watercourses and caves. The water in which they naturally live consists mainly of rainwater. As a result, they have these specific requirements regarding the water values, since rainwater differs significantly from our tap water.

Tap water is not sufficient to achieve the ideal water values. Tap water usually has a higher pH, KH, GH and conductivity than the values ​​Caridina shrimp need. Fortunately, solutions are available, such as the use of osmosis water, pH-lowering soil substrates and mineral salts, that allow you to adjust these water parameters. Using these methods you can create the ideal environment for keeping Caridina shrimp.

Despite these requirements, Caridina are really beautiful shrimp to keep! They are active and peaceful animals that actively swim around in your aquarium and are busy looking for food all day long. They are hard workers and excellent cleaners. They feed on algae and organic matter, so they play a natural role in keeping the aquarium clean. Observing their lively behavior, intense colors and diverse patterns is a fun hobby that can quickly get out of hand.

Water values

Caridina shrimp have specific requirements to maintain optimal health and well-being. It is important to understand that these beautiful shrimp need a carefully curated habitat to thrive. For example, they set specific requirements for the water values, such as the pH value, the hardness and the temperature of the water.

Minimum size: 15 to 20 liter aquarium
Temperature: 18 to 28 degrees - preferably around 22 degrees
PH value: 6 to 7
GH Value: 5 – 6
KH: As close to 0 as possible
N02: 0
Conductivity: 200-300ms
Equipment: Lots of plants, mosses and wood

There are several methods available to achieve the correct water values ​​for Caridina shrimp. One option is to use rainwater or osmosis water, because these water sources have a different composition than tap water. By combining rainwater or osmosis water with a pH-lowering soil, you can more easily achieve the desired pH value and keep it stable.

Measuring the water values ​​is essential and can be done using electric meters or drop tests. Electric meters provide real-time information on key parameters such as pH, gH, kH and conductivity, while drop tests can be performed at home and provide valuable information on the condition of the aquarium water.

Power supply

A balanced and appropriate diet is of great importance for the health and well-being of Caridina shrimp. These beautiful shrimp are omnivores and need a varied diet to stay in optimal condition. Although they mainly consume plant foods, it is important to meet their nutritional needs.

Caridina shrimp's diet can consist of a variety of nutrients, including algae, dead plant debris, and special shrimp feed. Algae is a natural food source for shrimp and can be obtained from algae on the plants in the aquarium or through algae wafers. Offering dead plant remains, such as dried leaves or pieces of vegetables, is also beneficial for their diet.

In addition to plant foods, Caridina shrimp also require protein-rich foods. This can be offered in the form of special shrimp feed that is fully balanced to contain all essential nutrients.

It is advisable to keep Caridina shrimp's diet varied and to feed it regularly. Providing a balanced diet allows shrimp to receive the necessary nutrients essential for healthy growth and reproduction. Observing the shrimp's feeding behavior can also provide valuable information about their health and well-being.

Aquascaping With Plants And Mosses

When setting up a shrimp aquarium, it is very important to meet the natural needs of your Caridina shrimp as prey. Shrimp attach great importance to an environment with sufficient hiding places, as this creates a sense of security. Interestingly, you will be able to see more of your shrimp when they feel safe. Adding numerous hiding places to the aquarium is therefore essential.

When setting up a shrimp aquarium, it is therefore crucial to provide an environment in which shrimps feel safe and comfortable. Adding enough plants not only provides hiding places, but also contributes to a healthy ecosystem and provides shrimp with food sources. A well-appointed shrimp aquarium with lush vegetation provides shrimps with the ideal environment to thrive and enjoy a colorful and fascinating life

Aquarium Plants and Mosses

Plants play an essential role in your Caridina shrimp aquarium. They not only serve as important shelters, but also help create a healthy ecosystem. Plants play a vital role in maintaining optimal water quality by absorbing excess nutrients and reducing algae growth. They provide a stable environment and filter harmful substances from the water.

In addition, plants provide shrimp with the opportunity to find food and feed. They can feed on the algae and biofilm that grow on the plants. This natural food supply ensures a varied diet and contributes to the well-being of the shrimps.

Adding various types of plants, such as moss balls, floating plants and ground cover plants, ensures a varied landscape in the shrimp aquarium. This provides shrimp with different levels of hiding places and creates a visually appealing environment. The use of floating plants can also provide diffused light, which is beneficial for the well-being of the shrimp.
