Blue Velvet Shrimp Care Guide: The Stunning Blue Neocaridina

Blue velvet shrimp are one of the most striking color morphs of the beloved Neocaridina davidi. Their deep, saturated blue coloration makes them stand out in any planted aquarium, and they're just as hardy and beginner-friendly as their red cherry shrimp cousins.

If you're looking to add a splash of color to your aquarium without the demanding care requirements of Caridina species, blue velvets are an excellent choice. They breed readily, tolerate a wide range of water parameters, and their striking color only gets better in subsequent generations of a well-maintained colony.

Quick Facts: Blue Velvet Shrimp at a Glance

Blue Velvet vs Blue Dream vs Blue Jelly: What's the Difference?

The blue Neocaridina naming gets confusing fast. Here's what you need to know:

Blue Velvet shrimp have a deep, dark, almost navy blue coloration. The blue is saturated and opaque throughout the body, giving them that "velvety" appearance. They tend to be darker than other blue varieties.

Blue Dream shrimp are a lighter, brighter blue - more of a sky blue or powder blue. They're often more translucent than blue velvets, with a lighter overall appearance.

Blue Jelly shrimp have a pale, translucent blue body that's almost jelly-like in appearance. They're the lightest of the three varieties.

As one experienced keeper explained on r/shrimptank: "Blue velvet usually refers to blue carbons with no markings, making them often closely resemble blue jelly or blue dream with the exception that they generally still have slight spotting."

The important thing to understand: care requirements are identical for all blue Neocaridina varieties. They're all the same species, just different selectively-bred color forms. If you can keep cherry shrimp alive, you can keep any blue variety alive.

Blue Velvet Shrimp Color Grades

Like cherry shrimp, blue velvets come in different quality grades based on color intensity:

Pro tip: Start with mid-grade shrimp if you're on a budget. Through selective breeding (culling low-grade offspring), you can improve color quality over generations. Many hobbyists have built stunning high-grade colonies from humble beginnings.

Ideal Water Parameters for Blue Velvet Shrimp

Blue velvets are hardy Neocaridina that tolerate a surprisingly wide range of parameters. Here's what to aim for:

◆Stability Over Perfection

The single most important rule: stable parameters matter more than perfect parameters.

One frustrated beginner on r/shrimptank shared their experience: "Neos can live and breed in pH 6.5-8.0, GH 4-12 and KH 1-6, but there are a few factors to that. The water that they're born in is the biggest consideration. You can easily take shrimp that were born in 7.0 pH and have them adapt to 6.5 or 7.5, however if the shrimp is born in 7.5 it will likely die if you try to move it into 6.5."

The takeaway? Don't chase perfect numbers. Find out what parameters the shrimp were raised in (ask the seller), match those as closely as possible, and keep them stable.

◆High TDS Problems

If you have very hard tap water (TDS above 400 ppm), you may need to dilute with RO water or distilled water. As one keeper advised: "Do a 50% water change with distilled water or RO water. That would still only lower your TDS by half. You'd need to do it again in a week or so but you have too many minerals in your water column and it's making your shrimps' shells brittle."

Tank Setup for Blue Velvet Shrimp

◆Tank Size

Blue velvets can technically survive in tanks as small as 5 gallons, but we recommend 10 gallons minimum for a thriving colony. Larger tanks provide:

• •More stable water parameters
• •More grazing surface for biofilm
• •Room for the colony to grow without overcrowding
• •Better buffering against mistakes

Recommended: Aqueon 10 Gallon Tank - Affordable and reliable starter tank.

◆Filtration

Sponge filters are the gold standard for shrimp tanks:

• •Baby shrimp can't get sucked in
• •Massive surface area for beneficial bacteria
• •Shrimp love grazing on the sponge surface
• •Gentle water flow that won't stress shrimp

Our Pick: Aquarium Co-Op Coarse Sponge Filter - Excellent biological filtration and shrimp-safe design.

You'll also need an air pump to power the sponge filter:

• •Tetra Whisper Air Pump - Quiet and reliable.

◆Substrate

Darker substrates make blue shrimp pop visually. Black sand or dark soil substrates provide the best contrast for showing off that blue coloration.

• •Black substrate: Maximum visual impact
• •Active substrate: Buffers pH and provides minerals (great for planted tanks)
• •Inert sand/gravel: Works fine, won't affect water chemistry

Recommended: Fluval Stratum - Active substrate that's ideal for planted shrimp tanks.

◆Heating

Blue velvets prefer slightly cooler temperatures than tropical fish. In most homes, you may not even need a heater. If your room temperature drops below 65°F regularly, add a small heater.

Recommended: Fluval E Series Heater - Accurate temperature control with digital display.

◆Plants and Hardscape

Live plants are essential for a thriving blue velvet colony:

• •Java Moss: Perfect for baby shrimp to hide in
• •Anubias: Hardy and provides grazing surfaces
• •Java Fern: Low-light tolerant and shrimp-safe
• •Bucephalandra: Beautiful and slow-growing
• •Marimo Moss Balls: Shrimp love grazing on them

Driftwood and rocks provide additional hiding spots and surface area for biofilm growth. Blue velvets will spend hours picking at driftwood.

Feeding Blue Velvet Shrimp

Blue velvets are not picky eaters. In a well-established tank with plenty of plants and biofilm, they can survive without supplemental feeding. However, for optimal health and color, provide:

◆Commercial Foods

• •Shrimp pellets/wafers: Hikari Shrimp Cuisine - Balanced nutrition
• •Algae wafers: For grazing and supplemental feeding
• •Shrimp-specific foods: GlasGarten Shrimp Dinner Pads - Premium option

◆Natural Foods

• •Blanched vegetables (zucchini, spinach, cucumber)
• •Indian almond leaves (provide beneficial tannins)
• •Mulberry leaves
• •Biofilm on driftwood and rocks

◆Feeding Schedule

Feed sparingly - overfeeding is worse than underfeeding. A good rule:

• •Established tank: Feed 2-3 times per week
• •New tank: Feed every other day until biofilm develops
• •Remove uneaten food after 2-3 hours to prevent water quality issues

Breeding Blue Velvet Shrimp

One of the best things about blue velvets: they breed readily with minimal intervention. If you have healthy males and females in good water conditions, they will reproduce.

◆Sexing Blue Velvet Shrimp

◆The Breeding Process

1. •Saddle development: Female develops a saddle (yellow or blue mass) behind her head
2. •Molting: Female molts and releases pheromones
3. •Mating: Male fertilizes the eggs within hours of molt
4. •Berried female: Female carries 20-30 eggs under her tail for 3-4 weeks
5. •Hatching: Fully-formed miniature shrimp emerge (no larval stage)

◆Optimal Breeding Conditions

• •Temperature: 74-76°F (slightly warmer encourages breeding)
• •Plenty of hiding spots for babies
• •Stable parameters (stress stops breeding)
• •Good nutrition with calcium for shell development

◆Improving Color Quality

To maintain or improve the blue color in your colony:

1. •Cull low-grade offspring: Remove shrimp with poor coloration to a separate tank
2. •Keep high-grade specimens together: Let them breed to reinforce good genetics
3. •Don't mix with other Neocaridina colors: Interbreeding produces wild-type brown offspring
4. •Good nutrition: Quality food supports color development

Tank Mates for Blue Velvet Shrimp

Blue velvets are peaceful and get along with most small, non-aggressive fish. However, almost any fish will eat baby shrimp if given the opportunity.

◆Safe Tank Mates

• •Otocinclus catfish: Gentle algae eaters, won't bother shrimp
• •Small Corydoras: Bottom-dwelling and peaceful
• •Snails: Nerite, mystery, and ramshorn snails are all compatible
• •Other Neocaridina: BUT avoid mixing colors (see below)

◆Risky Tank Mates

• •Bettas: Hit or miss - some ignore shrimp, others hunt them
• •Guppies/Endlers: Will eat babies, adults usually safe
• •Small tetras: May pick off babies

◆Avoid Completely

• •Cichlids: Will eat shrimp on sight
• •Goldfish: Too messy and will eat shrimp
• •Larger fish: Anything that can fit a shrimp in its mouth will try

◆The Color Mixing Problem

Do not keep blue velvets with cherry shrimp, yellow shrimp, or other Neocaridina colors in the same tank. They will interbreed, and the offspring will gradually revert to wild-type brown coloration over generations. Keep your colors separate!

Common Issues and Solutions

◆Shrimp Deaths After Purchase

The most common complaint: "I just got blue velvets and half of them died within days!"

This usually comes down to acclimation shock. Blue velvets may be hardy, but sudden parameter changes can still kill them. Solutions:

• •Drip acclimate for 2-3 hours minimum: Slowly introduce tank water to their bag
• •Match source parameters: Ask the seller what parameters they were raised in
• •Don't change multiple things at once: Stable is better than perfect

◆Color Fading

If your blue velvets are losing their color:

• •Stress: Check water parameters and look for sources of stress
• •Poor genetics: Low-grade shrimp may never have intense color
• •Age: Older shrimp sometimes fade
• •Substrate: Light-colored substrates can wash out their appearance

◆Molting Problems

Failed molts are often caused by mineral deficiencies or parameter swings:

• •Ensure adequate GH (4-8 dGH minimum)
• •Add mineral supplements if using RO water
• •Avoid sudden temperature or pH changes
• •Provide calcium sources (cuttlebone, mineral supplements)

Where to Buy Blue Velvet Shrimp

◆Online Retailers

Buying online often gets you healthier shrimp from specialized breeders:

• •Aquatic Arts: Good selection of grades
• •The Shrimp Farm: Specialized shrimp retailer
• •eBay/Aquabid: Private breeders (check ratings carefully)

◆Local Fish Stores

Hit or miss. Chain pet stores rarely carry blue velvets. Local specialty aquarium stores are more likely to have them. Always ask:

• •What parameters are they kept in?
• •How long have they been in the store?
• •Can you see them eating?

◆Pricing Expectations

• •Low-grade: $2-3 each
• •Mid-grade: $3-4 each
• •High-grade: $5-7 each
• •Top-grade: $8-12 each

Buy in groups of 10+ for a healthy starting colony and to get the best prices.

Final Thoughts: Are Blue Velvet Shrimp Right for You?

Blue velvet shrimp are perfect for:

• •Beginners who want something more unique than red cherries
• •Planted tank enthusiasts looking for algae control and visual interest
• •Anyone who wants an easy-breeding, low-maintenance aquatic pet

They're not ideal if:

• •You already have other color Neocaridina (they'll interbreed)
• •You want to keep them with aggressive fish
• •You're not ready to maintain stable water parameters

For most hobbyists, blue velvets hit the sweet spot: beautiful enough to be impressive, hardy enough to forgive mistakes, and prolific enough to build a thriving colony. Give them stable water, decent food, and a planted tank, and they'll reward you with years of entertainment.

Frequently Asked Questions

◆Are blue velvet shrimp hard to keep?

Blue velvet shrimp are Neocaridina, so they're just as easy to keep as cherry shrimp. They tolerate a wide range of water parameters and breed readily in most setups. They're an excellent choice for beginners who want something different from red.

◆What is the difference between blue velvet and blue dream shrimp?

Blue dream shrimp were bred from chocolate Neocaridina, while blue velvets come from blue carbon rilis. In practice, they look nearly identical and have the same care requirements. Blue dreams tend to have slightly deeper, more solid coloring.

◆Can blue velvet shrimp live with cherry shrimp?

You can keep blue velvet and cherry shrimp together, but they'll interbreed since they're both Neocaridina davidi. Their offspring will gradually revert to wild-type brown coloring over several generations. Keep them separate if you want to maintain color.

◆How do you get deeper blue color in shrimp?

Selectively breed your highest-grade shrimp by removing lighter-colored ones from the colony. Dark substrate, good nutrition with color-enhancing foods, and stable water parameters all help intensify blue coloring over generations.
