What Do Freshwater Aquarium Shrimp Eat

Freshwater shrimp can be found in areas with warm water in the Southern US, Mexico, and Central and South America. They come in diverse and vibrant colors. Without wasting much time, let’s dive deep into what shrimp eat in the freshwater aquariums and the care guides.

Shrimp tank

Freshwater shrimp can be kept in most tropical freshwater fish aquariums, like tetras, and tiger barbs. However, setting up a shrimp tank can be different from setting up a fish tank. Then, how to set up a shrimp tank, and how to care for shrimp in aquariums?

How to set up a shrimp tank

The basic steps include adding substrate, adding aquarium decorations, filling the aquarium with water, cycling your tank, and introducing shrimp. Next, let’s learn more about the shrimp tank setup.

Tank size

You should prepare a tank first. Although most shrimp are small, the minimum tank size can be about 2 – 5 gallons. However, in general, the larger, the better if you keep an amount of shrimp.

Aquarium substrate

Fine gravel, sand, and aquarium soil are excellent alternatives. However, it is better to rinse the substrate before adding it to aquariums. Otherwise, your aquarium water will be cloudy for a few days. Generally, just keep the substrate for about 1–3 inches in height. Because too deep a substrate would lead to a build-up of anaerobic gas, which is not good for shrimp tanks.

Aquarium decorations

Shrimp need hiding places. You can create hiding space with aquarium decorations, like wood, caves, rocks, ornament tree trunk, or others. Plus, microorganisms will grow on the surface of these aquarium objects. And it can be another food source for shrimp.

Aquatic plants

Aquatic plants provide more hiding places for shrimp. The available aquatic plants can be Anubias, Java moss, Java fern, and moss balls. Plus, adding some aquatic plants can improve the ornamental value of shrimp tanks.

Regular water changes

It is vital to change the water once every two weeks. During the water change process, you can also clean the substrate with an electric vacuum cleaner. Then, the aquarium water quality in the shrimp tank would not get poor.

Monitor water parameters

Frequent water parameter fluctuation would cause shrimp death. It is better to test the water parameters regularly, like TDS, water temperature, ammonia level, nitrite level, nitrate level, pH level, etc. TDS measures the total dissolved solids in aquarium water. Too much TDS would pose threats to shrimps’ health. Take ghost shrimp as an example, the ideal TDS ranges from 150 to 200.

Necessary aquarium equipment

  • Aquarium light

Seeing that there are aquatic plants in freshwater shrimp aquariums, adding an aquarium light may be needed. Any planted aquarium LED lights can be optimal options. Just choose one according to the tank size and plants’ needs.

  • Aquarium heater

Whether you should add an aquarium heater depends on the shrimp’ needs. Commonly, it is better to keep the water temp between 70℉-79℉. Hence, in some areas, it may be necessary to add an aquarium heater to keep a stable and warm water temperature.

  • Aquarium filter

The sponge filter is perfect for shrimp tanks. Because it is effective and easy to install. Furthermore, you should make sure that the filter in shrimp tanks will not suck away the small shrimp. Additionally, you need to clean the sponge once a month.
