Origin and Distribution

Blue Velvet Shrimp are selectively bred from the wild Neocaridina davidi species, native to Taiwan’s freshwater rivers and streams. Their adaptability to various water conditions has contributed to their widespread popularity in the aquarium hobby.

Colors and Markings

These shrimp exhibit a striking, uniform blue coloration that can range from light to deep shades, depending on genetics and environmental factors. Their translucent bodies may display subtle dark spots, particularly concentrated near the head and legs, adding to their unique appearance.

Tankmates

Blue Velvet Shrimp are peaceful and can coexist with other non-aggressive species that won’t prey on them. Suitable tankmates include:

• Small, peaceful fish like Neon Tetras and Harlequin Rasboras
• Other dwarf shrimp species
• Snails such as Nerite and Mystery Snails

Avoid housing them with larger or predatory fish that may view them as food.

Habitat and Care

To replicate their natural environment:

• Tank Size: A minimum of 5 gallons is recommended, though larger tanks provide more stable water parameters.
• Substrate: Dark-colored substrates enhance their blue coloration and provide a natural setting.
• Plants: Incorporate live plants like Java Moss, Anubias, and floating species to offer hiding spots and surfaces for biofilm growth.
• Filtration: Use gentle filtration to maintain water quality without creating strong currents.
• Lighting: Moderate lighting supports plant growth and showcases their vibrant color.

Regular water changes and monitoring of parameters are essential to maintain optimal health.

Diet and Feeding

As omnivores, Blue Velvet Shrimp feed on algae, biofilm, and detritus. To supplement their diet:

• Provide high-quality shrimp pellets or flakes
• Offer blanched vegetables like spinach, zucchini, and carrots
• Include occasional protein sources such as bloodworms or brine shrimp

Feed them small amounts once or twice daily, ensuring they consume all food within a few hours to prevent water quality issues.

Gender Differences

Females are generally larger and display more intense blue coloration compared to males. They also develop a “saddle” marking behind the head, indicating the presence of eggs in the ovaries.

Breeding

Breeding Blue Velvet Shrimp is straightforward under suitable conditions:

• Water Parameters: Maintain stable, clean water with temperatures between 72–82°F (22–28°C).
• Habitat: Provide ample hiding spots and a mature tank with established biofilm.
• Process: Females carry eggs under their abdomen for about 2–3 weeks until hatching. The hatched juveniles are miniature versions of adults and can feed on the same diet.

A well-maintained environment encourages continuous breeding, leading to a thriving shrimp colony.
