Crystal Black Shrimp: Rare Species Care

Crystal Black Shrimp (Caridina cf. cantonensis) are a rare and sought-after species of freshwater shrimp, known for their stunning black and translucent appearance. These shrimp are not only attractive to look at, but they are also relatively easy to care for, making them a popular choice among aquarium hobbyists. In this article, we’ll explore everything you need to know about keeping Crystal Black Shrimp in your aquarium.

Natural Habitat

Crystal Black Shrimp are native to the slow-moving rivers and streams of southern China. They live in a variety of habitats, from clear, pristine streams to murky, polluted rivers. The water in their natural habitat is typically slightly acidic and low in minerals, making it ideal for these delicate creatures.

Tank Requirements

To keep Crystal Black Shrimp healthy and happy in your aquarium, it’s important to provide them with the right water conditions. They prefer a pH between 6.0 and 7.2, and a total hardness of 4-8 dGH. It’s also important to maintain stable water parameters and avoid sudden fluctuations.

When it comes to tank size, a 5-gallon tank is suitable for a small colony of Crystal Black Shrimp. However, if you’re planning on keeping a larger colony, you may need a bigger tank. As these shrimp are relatively small, you don’t need a lot of swimming space, but they do appreciate plenty of hiding places, such as caves, plants, and other decorations.

Crystal Black Shrimp are omnivores, which means that they will eat a variety of foods, including both plant and animal matter. A balanced diet for these shrimp should include a variety of foods, such as blanched vegetables, sinking pellets, and frozen or live foods. It’s also important to feed them small, frequent meals, as opposed to large, infrequent ones.


Crystal Black Shrimp are relatively easy to breed in captivity, making them a great choice for those who want to start a breeding program. The breeding process begins with a mated pair of adult shrimp, which will lay eggs on the underside of leaves or other surfaces in the aquarium. The eggs hatch into larvae, which are carried by the female until they reach the juvenile stage.

To ensure successful breeding, it’s important to provide the right water conditions, as well as plenty of hiding places for the adult shrimp and their offspring. It’s also important to keep the water well-oxygenated, as this will help to prevent stress and promote healthy growth.


Crystal Black Shrimp are a beautiful and relatively easy-to-care-for species of freshwater shrimp that make a great addition to any aquarium. With the right water conditions, diet, and plenty of hiding places, you can keep these stunning creatures healthy and happy for years to come.
