Overview

Blue Velvet Shrimp are a stunning blue color morph of Neocaridina davidi, the same species as Cherry Shrimp. Through selective breeding, aquarists have developed these gorgeous blue shrimp that range from light sky blue to deep sapphire.

Combining the hardiness and easy care of Neocaridina with beautiful blue coloration, Blue Velvet Shrimp are perfect for aquarists wanting something unique without the demanding requirements of Caridina species. They breed readily and make excellent additions to planted nano tanks.

Blue velvet shrimp are a blue line of Neocaridina davidi, the same species as the red cherry shrimp, with a wild ancestor from Taiwan and the color fixed in captivity. A velvet adult is about 1 to 1.5 inches and is old at 1 to 2 years. A tank of 5 gallons or more can hold a colony. They are listed as beginner animals and as prolific breeders. The blue is a grade, not a separate species, and it does not stay blue if you mix it with red, yellow, or wild-type Neocaridina.

They prefer cooler water than a typical tropical community. The card lists 68 to 74°F, pH in a broad 6.5 to 8.0 band with a tighter 6.8 to 7.5 called out beside it, general hardness 6 to 8 dGH, carbonate hardness 2 to 5 dKH, and TDS around 150 to 250 ppm. A heater set to 80°F for a betta is already above their preferred band. Zero ammonia, zero nitrite, and nitrate under 20 ppm are the readings that keep a blue colony from crashing after a top-off. A 5-gallon tank has very little dilution, so the small minimum is not a low-maintenance bowl.

They eat biofilm, soft algae, and leftover food. A shrimp-specific pellet or a blanched vegetable keeps a colony fed once the tank is too clean to graze. They are not a substitute for a bamboo shrimp, and they will not clear hair algae by themselves. Copper medications kill Neocaridina. Any treatment sold for ich that lists copper is a colony wipeout. Move the shrimp, or do not use the copper.

Natural Habitat

While Blue Velvet Shrimp are selectively bred, understanding their wild ancestor helps.

• Wild Origin: Neocaridina davidi from Taiwan streams
• Environment: Slow-moving freshwater with vegetation
• Substrate: Rocky bottoms with leaf litter
• Diet: Biofilm, algae, and decaying plant matter

Tank Requirements

Blue Velvet Shrimp thrive in well-maintained planted tanks.

• Tank Size: Minimum 5 gallons; 10+ for colonies
• Substrate: Dark substrates enhance blue coloration
• Filtration: Sponge filter recommended for shrimplet safety
• Plants: Java moss, Java fern, Anubias, floating plants
• Hiding Spots: Driftwood, cholla wood, shrimp caves
• Lighting: Moderate; supports plant growth and viewing

Water Parameters

Blue Velvet Shrimp are adaptable to various water conditions: Your aquatic veterinarian and experienced Blue Velvet Shrimp owners can offer perspective tailored to your situation.

Diet & Feeding

Blue Velvet Shrimp are easy to feed: Your aquatic veterinarian and experienced Blue Velvet Shrimp owners can offer perspective tailored to your situation.

• Biofilm: Primary food source in established tanks
• Algae: Graze on various algae types
• Commercial Foods: Shrimp pellets, wafers, specialty foods
• Blanched Vegetables: Zucchini, spinach, cucumber
• Color-Enhancing Foods: Spirulina, astaxanthin-rich foods
• Calcium: Cuttlebone, mineral supplements for molting

Feeding Schedule: Feed sparingly every 1-2 days. Mature tanks with biofilm require less supplementation.

Proper nutrition for Blue Velvet Shrimp requires understanding not just what to feed, but how feeding strategies affect health, behavior, and water quality. A disciplined approach to feeding, where your Blue Velvet Shrimp receives the right amount of appropriate food at consistent intervals, is one of the most impactful things you can do for both the fish and the overall aquarium ecosystem.

Diet variety is essential for optimal Blue Velvet Shrimp health because no single commercial food provides the complete nutritional profile these fish require. Observing your Blue Velvet Shrimp's response to different food types also provides useful health information, as reduced interest in normally preferred foods is often an early indicator of illness.

Behavior & Temperament

Blue Velvet Shrimp behaviors mirror other Neocaridina: Your aquatic veterinarian and experienced Blue Velvet Shrimp owners can offer perspective tailored to your situation.

• Peaceful: Non-aggressive to all tankmates
• Social: Thrive and display more activity in groups
• Active Grazers: Constantly foraging for food
• Molting: Regular molting indicates good health
• Breeding Behavior: Females "swim" when releasing pheromones

Breeding really is easy if the parameters stay put. Females carry eggs under the tail for a few weeks and release tiny copies of the adults. There is no brackish larval stage, which is the difference between this species and an Amano. A 5-gallon tank fills up. Plan a place for extras before the first berried female, or the colony will stall when nitrate climbs and food runs short. One to 2 years is the adult life, so the colony persists by breeding, not by the original shrimp living a decade.

Color fades for three reasons: poor food, a cross with another color line, and stress from heat or a dirty tank. If you want blue offspring, keep only blue velvet shrimp in that tank. A single red cherry dropped in as a hitchhiker will throw wild-type and muddy young within a generation. Males stay smaller and less opaque. Females show the saddle of eggs behind the head. A colony of only males will look tidy and then simply age out.

Feeding behavior in Blue Velvet Shrimp reveals much about their ecological role and can be leveraged by keepers to promote natural behaviors and reduce aggression. Observing when, where, and how your Blue Velvet Shrimp feeds provides diagnostic information about their comfort level, health status, and social standing. Many successful Blue Velvet Shrimp keepers use varied feeding strategies including target feeding, scatter feeding, and enrichment feeders to promote natural foraging behaviors and reduce competition-related stress.

Color Grades & Varieties

Blue Neocaridina come in several varieties.

• Blue Velvet: Solid light to medium blue
• Blue Dream: Deeper, more intense blue
• Blue Diamond: Very dark blue, nearly black
• Blue Jelly: Translucent light blue
• Carbon Rili: Blue with clear sections

Compatibility

Blue Velvet Shrimp are vulnerable and need safe tankmates: Every time you adjust for something the Blue Velvet Shrimp actually does, rather than what breed profiles predict, results improve.

Good Tankmates

• Other Neocaridina shrimp (may interbreed and lose color)
• Small peaceful fish: Otocinclus, Pygmy Corydoras
• Snails: Nerite, Mystery, Ramshorn
• Amano Shrimp (won't interbreed)
• Small rasboras (Chili, Exclamation Point)

Avoid

• Most fish larger than 2 inches
• Cichlids and aggressive fish
• Bettas (variable - some are shrimp-safe)
• Crayfish and crabs
• Other Neocaridina colors (if maintaining pure lines)

Breeding

Blue Velvet Shrimp breed readily in home aquariums.

• Sexual Maturity: 3-4 months old
• Sexing: Females larger with curved underbelly and visible saddle
• Mating: Occurs after female molts
• Eggs: Female carries 20-30 eggs for 28-35 days
• Shrimplets: Hatch as miniature adults
• Color Development: Juveniles gain color as they grow

Breeding for Color

• Cull lighter-colored individuals to maintain line quality
• Select breeding stock with deepest blue coloration
• Avoid introducing other Neocaridina colors
• Quality food and conditions improve offspring color

Health Issues

Common health concerns for Blue Velvet Shrimp.

• Failed Molts: Usually from mineral deficiency
• Color Loss: Stress, poor diet, or genetics
• Bacterial Infections: White/milky appearance
• Parasites: Vorticella, Scutariella japonica
• Planaria: Flatworms that can harm shrimp

For Blue Velvet Shrimp, prevention is always better than treatment.

Recognizing early signs of disease in Blue Velvet Shrimp requires a trained eye and consistent observation. Establishing a daily observation routine—even just a few minutes of focused attention during feeding—helps you develop a baseline understanding of what normal behavior looks like for your specific Blue Velvet Shrimp, making deviations immediately apparent.

Quarantine protocols represent one of the most impactful health management practices available to Blue Velvet Shrimp keepers. This single practice prevents the majority of disease outbreaks in established aquariums and is considered essential by virtually all experienced Blue Velvet Shrimp keepers.

Is This Species Right for You?

Blue Velvet Shrimp Are Perfect For:

• Beginners wanting colorful shrimp

Adding a Blue Velvet Shrimp to your setup works best when you have honestly evaluated your tank size, maintenance habits, and budget.

Experienced Blue Velvet Shrimp keepers will tell you that the learning curve is steepest in the first few months. After that, maintenance becomes routine.

Cost of Ownership

These figures are averages, not guarantees. Some Blue Velvet Shrimp owners spend less; others spend more due to health complications or premium product preferences.

The true cost of keeping Blue Velvet Shrimp extends well beyond the initial purchase price and basic equipment. Many aspiring Blue Velvet Shrimp keepers underestimate these ongoing costs, which can lead to cut corners that ultimately compromise fish health and result in even greater expenses. A realistic budget that accounts for both routine maintenance and occasional replacement of equipment provides a more accurate picture of what Blue Velvet Shrimp keeping actually costs.

Heaters, filters, lights, and pumps all have finite lifespans, and their failure—particularly heater or filter failure—can have catastrophic consequences for Blue Velvet Shrimp if not addressed promptly. Many experienced Blue Velvet Shrimp keepers also invest in battery-operated air pumps and backup heaters as insurance against power outages, which can be lethal to tropical species within hours depending on ambient room temperature.

The cost-benefit analysis of quality versus budget equipment deserves careful consideration for Blue Velvet Shrimp keepers. This is particularly true for Blue Velvet Shrimp, where the animals themselves, along with any tank mates, plants, and established biological filtration, represent a significant investment of both money and time that is worth protecting with reliable equipment.

Related Species

If you're interested in Blue Velvet Shrimp, consider these related species.

• Cherry Shrimp - Same species, red color morph
• Crystal Red Shrimp - More challenging Caridina
• Amano Shrimp - Great algae eaters
• Ghost Shrimp - Very affordable option

Blue velvet shrimp are a Neocaridina color line. A colony in a mature planted tank of 5 gallons or more eats biofilm, soft algae, and a pinch of sinking shrimp food. The blue stays deep when the water is stable, and a failed molt usually follows a sudden drop in minerals or a very large water change.
