Black Diamond Chocolate Shrimp Care & Tank Requirements

Black Diamond Chocolate Shrimp (Neocaridina denticulata sinensis) are beautiful, peaceful, and easy-to-care for freshwater shrimp. They are perfect for beginners to shrimp keeping and make a great addition to any community aquarium.

Chocolate shrimp are very versatile and can be kept in a wide range of aquarium setups. They are relatively undemanding when it comes to water parameters and will thrive in most types of freshwater aquariums.

The Best Aquarium Size for Chocolate Shrimps

The minimum size aquarium for keeping chocolate shrimps is 5 gallons. A larger aquarium is always better as it will provide more space for the shrimp to hide and forage and will also help to maintain water quality.

Chocolate shrimp are very active and love to swim around, so a taller aquarium is better than a wide one. A 10 gallon aquarium is a good size for a small group of shrimp. Also, remember that you will need to provide hiding places for your shrimp, so make sure you have plenty of live plants or other decorations in the tank.

Water Parameters

Chocolate shrimp are very tolerant of a wide range of water parameters. They can live in water with a pH of 6.0–8.0, hardness of 2–20 dGH, and a temperature of 72–78 °F (22–26 °C). Also, chocolate shrimp do not need a very large tank. A 5–10 gallon tank is sufficient for a small colony of these animals.


Black Diamond Chocolate Shrimp are very sensitive to water conditions and need a well-filtered aquarium. A canister filter or sponge filter is ideal. Avoid using an undergravel filter, as it can trap and kill shrimp. Also, make sure that the filter intake is covered with a sponge or other material to prevent shrimp from being sucked into the filter.

Do Chocolate Shrimp Need an Air Pump?

An air pump is not necessary for keeping Black Diamond Chocolate Shrimp, but it will help to keep the water well oxygenated. A small air pump should be sufficient for a 10-gallon aquarium. This will help to keep your shrimp healthy and prevent them from getting sick.

Aquarium Lighting

Black Diamond Chocolate Shrimp are not very demanding when it comes to lighting. A low to moderate level of lighting will be fine for them. Also, they do not require any special lighting like full-spectrum lighting. So, they are perfect for people who do not want to spend a lot of money on lighting for their aquarium.

Plants and Decorations

Chocolate shrimp should be provided with plenty of hiding places and live plants to graze on. Java moss, Anubias, and Hornwort are all good plant choices for chocolate shrimp tanks. The plants will also help to keep the water quality high.

You can also use driftwood, rocks, and caves for hiding places and decorations. Be sure that any decorations you use are free of sharp edges that could injure the shrimp. The shrimp will also appreciate a layer of soft substrates such as sand or gravel to graze on.

What’s the Best Substrate for Chocolate Shrimps?

Black Diamond Chocolate Shrimp are not fussy when it comes to the substrate. They will do well in either sand or gravel. If you are keeping them with fish that like to dig, then sand may be the better option. Also, these shrimp will do best in an aquarium that has a dark substrate since they are darker-colored shrimp.

Food & Diet

Chocolate shrimp are omnivores by nature. In the wild, they feed on various types of algae, detritus, and small aquatic creatures. In captivity, you can feed them with a variety of foods, including live, frozen, or freeze-dried foods. You can also give them pellets or flakes designed for omnivores. It’s best to offer them a variety of foods to ensure they get all the nutrients they need.

What Can I Feed Chocolate Shrimp?

In captivity, chocolate shrimp can be fed various types of live, frozen, and freeze-dried foods. Some of the most common foods that are fed to these animals include:

  • Bloodworms
  • Brine shrimp
  • Daphnia
  • Mosquito larvae
  • Tubifex worms

It is also a good idea to supplement their diet with some high-quality pellet or flake foods that are designed for shrimp. Be sure to choose a food that does not contain any copper, as this can be toxic to shrimp.

How Often Do Chocolate Shrimp Need to Be Fed?

In a home aquarium, these shrimp can be fed once or twice a day. It is best to give them small amounts of food at a time so that they can eat all of it and there is no risk of overfeeding.

How Long Can a Chocolate Shrimp Go Without Food?

Chocolate Shrimp Breeding

Chocolate shrimp breeding is not difficult, but it does take some patience. These animals are not sexually dimorphic, which means that it is difficult to tell males from females just by looking at them. The best way to determine the sex of your shrimp is to look at their ventral (underneath) side. Females will have a slightly wider ventral side than males. Male shrimp also tend to be smaller than females.

If you want to breed your chocolate shrimp, it is best to start with a group of 6-10 animals. This will give you the best chance of getting a good mix of males and females. Once you have your breeding group, you will need to provide them with plenty of hiding places and plenty of food. These animals are not picky eaters and will accept most aquarium foods.

You should also make sure that the water parameters in your tank are within the ideal range for chocolate shrimp. These animals do not tolerate changes in water quality well, so it is important to keep the water in your tank clean and stable. Once your shrimp are acclimated to their new home, they will start to breed. The female shrimp will carry her eggs under her tail for about 2 weeks before they hatch.

After the eggs hatch, the fry (baby shrimp) will be free-swimming and will need to be fed very small foods. Baby brine shrimp or other similar foods are a good choice for fry. As the fry grows, you can start to feed them larger foods. Chocolate shrimp are not difficult to care for and will thrive in most home aquariums.
