Chocolate Shrimp (Black Rose)
Scientific Name: Caridina Cantonensis "Black Rose"
Wild Origin: Taiwan
Adult Size: 1.2in
The Chocolate Shrimp is a popular choice for freshwater shrimp hobbyists because of its intriguing dark color as well as being relatively easy to care for and breed. They stand out beautifully against a light colored substrate. Chocolate Shrimp make a striking and dynamic addition to a freshwater aquarium. These shrimp are very active as they scavenge the tank, cleaning up waste. They love to feed off of naturally occurring biofilm and algae, especially in a planted tank. For this reason, they can be quite low maintenance; in fact, they can even help keep your tank clean!
Chocolate Shrimp can withstand a pretty wide range of water parameters, and are not an aggressive species. This combined with their versatility makes them a good option as tank companions. Chocolate Shrimp breed easily, making them a good choice for beginners to freshwater shrimp hobby. The Chocolate Shrimp is a product of the selective breeding of the Red Cherry Shrimp for dark coloration, resulting in stunning hues from deep red to dark brown hues. They are also sometimes called Black Cherry Shrimp. Some of these shrimp have dark brown spotting and striping over translucent yellow.
Chocolate Shrimp are tolerant to a fairly wide range of water parameters, making them excellent for pairing with other species. As long as the shrimp are acclimated properly to your chosen parameters and are not subjected to extreme changes in temperature or acidity, they are adaptable. They will tolerate soft or hard water. The ideal water parameters are 70°-85° F with 7 to 7.5 pH. However, as mentioned, you may keep them outside of these parameters as long as the shrimp are protected from extreme or frequent fluctuations.

The Chocolate shrimp variety doesn't occur naturally in the wild, so breeding lines are entirely captive-bred and maintained by skilled breeders. Sexing Chocolate Shrimp can be somewhat difficult until the shrimp begin to mature. Female Chocolate Shrimp have slightly larger tails and display a “saddle” formation on the upper body, behind the head, where eggs are stored before fertilization. When female shrimp are “berried”, or have eggs ready for fertilization, the saddle shape will appear more prominent. Once the shrimp are fully-grown the males will be smaller than the females.
Chocolate Shrimp are eager breeders given comfortable water parameters and a sufficient food source. Once the shrimp reach maturity, and if there are males and females present, they should breed naturally and frequently. It is recommended to purchase 8-10 shrimp to ensure that there are enough male-female pairs for successful breeding. When female shrimp have eggs available for fertilization, they will molt and release pheromones that the male shrimp respond to with frenzy.
Once the shrimp breed, the eggs will gestate for about 2 weeks. The shrimp fry will feed from the same food sources as their parents, and will molt frequently during their early life stages. Leave molted shells in the tank, as the shrimp fry will consume them for extra minerals like calcium that will help their growth.
Keep in mind that if you are keeping shrimp with other species of fish, or possibly aggressive shrimp species, this may affect reproduction. If the shrimp feel threatened or don’t have places in your tank to hide, they may not breed.
