Black Rose Dwarf Shrimp (Neocaridina davidi var. 'Black Rose'): Care Guide and Origins

The Black Rose Dwarf Shrimp is a striking color variant of the popular Neocaridina davidi species, known for its glossy, deep-black coloration. These shrimp are a relatively new and increasingly popular choice for freshwater aquariums due to their bold appearance and hardy nature. Their contrasting color makes them stand out beautifully against green plants and colorful fish, adding an elegant touch to any tank setup.

Origins and Natural Habitat

The Black Rose Dwarf Shrimp is a selectively bred variety of Neocaridina davidi, which is native to the freshwater rivers and streams of Taiwan and China. In the wild, the species exhibits a more transparent or brownish coloration, which has been bred into various color morphs over time, such as the Fire Red and Black Rose varieties. Like their wild ancestors, these shrimp thrive in areas with plenty of plant cover and gentle water flow.

Aquarium Setup and Care

1. Tank Size
   Black Rose Dwarf Shrimp are small, reaching a maximum size of 1–1.5 inches (2.5–4 cm), and can comfortably live in tanks as small as 5 gallons (19 liters). However, larger tanks provide better water stability, making it easier to maintain the proper conditions for the shrimp to thrive.
2. Water Parameters
   Maintaining stable water parameters is essential for Black Rose Dwarf Shrimp to flourish:
   • Temperature: 65–80°F (18–27°C)
   • pH: 6.5–7.5
   • Water Hardness: Soft to moderately hard water (GH 4-8, KH 1-4)
   • Ammonia & Nitrite: 0 ppm
   • Nitrate: Less than 20 ppm

   Regular water changes of 10-20% weekly are necessary to keep the water clean and parameters stable. A sponge filter or a shrimp-safe filter that doesn’t pose a risk to their delicate bodies is the best choice.

3. Substrate and Plants Black Rose Shrimp appreciate a natural tank environment with lots of live plants and hiding places. A dark substrate, like black sand or shrimp-safe soil, not only makes the shrimp feel more secure but also enhances the contrast of their dark color. Popular plants like Java Moss, Anubias, and Cryptocoryne provide both cover and surfaces for biofilm to grow, which the shrimp will graze on.
4. Tank Mates
   As peaceful creatures, Black Rose Dwarf Shrimp need to be housed with non-aggressive tank mates to avoid predation. Suitable tank mates include:
   • Nano fish (Chili Rasboras, Galaxy Rasboras)
   • Small tetras (Ember Tetras, Neon Tetras)
   • Other dwarf shrimp species
   • Snails (Nerite Snails, Assassin Snails)

   Many hobbyists prefer species-only shrimp tanks to ensure the safety and longevity of their shrimp population, allowing them to breed without the risk of predators.

5. Diet Like other dwarf shrimp, Black Rose Shrimp are omnivores and will happily scavenge for food throughout the day, feeding on algae, biofilm, and decaying plant matter. Supplementing their diet ensures they get all the nutrients they need:
   • Algae wafers
   • Specialized shrimp pellets
   • Blanched vegetables (spinach, zucchini, cucumber)
   • Biofilm and microorganisms growing on plants and décor

   It's important not to overfeed, as excess food can pollute the water and negatively impact water quality.

Breeding Black Rose Dwarf Shrimp

One of the joys of keeping Black Rose Dwarf Shrimp is how easily they reproduce in a well-maintained aquarium. Here's what you need to know for successful breeding:

• Females, easily identifiable by their larger size and saddle (a yellowish patch of eggs developing inside), will carry eggs under their abdomen (swimmerets) for about 3-4 weeks.
• After this period, they release fully developed baby shrimp (shrimplets), which will begin to graze on biofilm and algae immediately.

For a higher survival rate of the young, ensure there is enough biofilm and small foods available, as shrimplets can’t consume larger food particles right away.

The Black Rose Dwarf Shrimp is an eye-catching and rewarding addition to any freshwater aquarium. Their stunning black color makes them a beautiful contrast to vibrant green plants, while their hardy nature ensures they can thrive in a wide range of water conditions. With proper care and stable water parameters, these shrimp will not only beautify your tank but also reproduce readily, offering aquarists the chance to enjoy a thriving colony.
