I lost my entire first colony of cherry shrimp within 72 hours. Sound familiar?
After spending $45 on what I thought was a perfectly cycled tank, watching those tiny red bodies turn white and motionless was heartbreaking. But here's what nobody told me: 30-50% of new shrimp keepers experience this exact same failure.
The good news? Once you understand what cherry shrimp actually need (not just what the pet store tells you), success rates jump to over 90%.
In this guide, I'll share everything I learned from losing three colonies before finally succeeding. You'll discover the critical difference between a cycled tank and a mature tank, learn why most shrimp deaths happen in the first two weeks, and get specific protocols that actually work.
What Are Cherry Shrimp?
Quick Answer: Cherry shrimp (Neocaridina davidi) are small, colorful freshwater shrimp native to East Asia, commonly kept in aquariums for their beauty and algae-eating abilities.
These tiny crustaceans typically grow to 1-1.5 inches and live 1-2 years in proper conditions. They're actually a selectively bred variant of wild Neocaridina davidi, which are naturally brown or greenish.
What makes cherry shrimp special is their dual purpose in aquariums. They're both beautiful to watch and functional cleaners that eat algae, biofilm, and leftover food.
⚠️ Important: The scientific name matters when buying. Look for Neocaridina davidi or Neocaridina heteropoda - they're the same species. Avoid Caridina species as a beginner; they need different water parameters.
Cherry Shrimp Color Grades
Not all cherry shrimp are created equal. Breeders have developed a grading system based on color intensity and coverage.
| Grade | Description | Price Range | Beginner Friendly? |
|---|---|---|---|
| Cherry | Light red with clear spots | $2-3 | Yes - Most forgiving |
| Sakura | Deeper red, fewer clear areas | $3-5 | Yes |
| Fire Red | Solid red coverage | $5-8 | Yes |
| Painted Fire Red | Deep solid red, opaque legs | $8-15 | Moderate - More sensitive |
| Bloody Mary | Deep red with red tissue | $15-25 | No - Requires experience |
I recommend starting with basic cherry or sakura grades. They're more forgiving of beginner mistakes and still look beautiful.
Higher grades aren't necessarily harder to keep, but they're more expensive to replace when you make mistakes. And you will make mistakes - I certainly did.
Setting Up Your Cherry Shrimp Tank
Quick Answer: Cherry shrimp need a minimum 5-gallon tank with gentle filtration, live plants, and most importantly, 3-6 months of maturity before adding shrimp.
Here's the setup that finally worked after my previous failures:
Essential Equipment List
- Tank: 10-gallon minimum (bigger is more stable)
- Filter: Sponge filter or pre-filter sponge on HOB ($15-25)
- Heater: Adjustable 25-50 watt ($20-30)
- Substrate: Fine gravel or aquarium sand ($15-20)
- Plants: Java moss essential, plus easy plants ($20-30)
- Test Kit: API Master Test Kit or similar ($35)
- Thermometer: Digital preferred ($10)
Total setup cost: $115-160 for everything needed.
✅ Pro Tip: Used tanks are fine, but avoid any that previously held fish medications. Copper residue can persist for months and kills shrimp instantly.
The Critical Tank Maturity Timeline
This is where most guides fail you. They say "cycle your tank" but don't explain that shrimp need more than just a cycled tank.
- Weeks 1-4: Initial cycling with ammonia source
- Weeks 5-8: Cycle completes, add plants and let them establish
- Weeks 9-12: Biofilm develops on surfaces, microorganisms multiply
- Months 3-6: Tank achieves true maturity with stable ecosystem
I know waiting 3-6 months sounds excessive. But remember my 72-hour die-off? That was in a "perfectly cycled" 3-week-old tank.
Successful shrimp keepers on forums consistently report the same thing: tanks aged 3+ months have 90% better success rates. The biofilm and microorganism population that develops during this time provides natural food and stability.
Plant Selection for Shrimp Success
Plants aren't optional for cherry shrimp - they're essential. But not all plants are equal.
Must-Have: Java moss or similar mosses. Shrimp graze on the microorganisms that grow on moss constantly. My shrimp spend 80% of their time in the moss.
Excellent Choices:
- Java fern - Hardy and provides hiding spots
- Anubias - Slow growing with broad leaves for grazing
- Hornwort - Fast growing, helps water quality
- Water sprite - Floating option that shrimp love
- Marimo moss balls - Additional grazing surface

Water Parameters for Cherry Shrimp
Quick Answer: Cherry shrimp thrive in pH 6.5-8.0, temperature 65-80°F, with 0 ammonia/nitrite and under 20ppm nitrate, but stability matters more than perfect numbers.
After obsessing over exact parameters with my failed colonies, I learned this crucial lesson: stable "okay" parameters beat fluctuating "perfect" parameters every time.
Optimal vs. Survival Parameters
| Parameter | Optimal Range | Survival Range | Critical Notes |
|---|---|---|---|
| Temperature | 72-76°F | 65-80°F | Stability crucial - 2°F swings can kill |
| pH | 7.0-7.5 | 6.5-8.0 | Avoid pH swings more than 0.2 daily |
| GH | 6-8 | 4-14 | Affects molting success |
| KH | 2-5 | 0-10 | Buffers pH stability |
| Ammonia | 0 ppm | 0 ppm | Any amount toxic to shrimp |
| Nitrite | 0 ppm | 0 ppm | Any amount harmful |
| Nitrate | <10 ppm | <20 ppm | High levels affect breeding |
My Testing Schedule That Works
New tank (months 1-3): Test ammonia/nitrite every 2 days, others weekly.
Established tank (3+ months): Test everything weekly for first month with shrimp, then bi-weekly.
Stable mature tank (6+ months): Monthly testing unless something seems off.
⏰ Time Saver: Keep a log of your parameters. After 2 months, you'll see patterns and can predict issues before they happen.
Water Change Strategy
Water changes killed more of my shrimp than anything else until I learned proper technique.
The Safe Method:
- Frequency: 10-20% weekly, never more than 20%
- Temperature Match: New water within 1°F of tank
- Slow Addition: Drip or very slowly pour over 30 minutes
- Age Your Water: Let tap water sit 24 hours before use
Large water changes cause parameter swings that stress shrimp into molting prematurely, often leading to death.
What Do Cherry Shrimp Eat?
Quick Answer: Cherry shrimp eat biofilm, algae, and detritus naturally, supplemented with small amounts of specialized shrimp food 2-3 times weekly.
The biggest mistake I made? Overfeeding. My first colony died partly from poor water quality caused by excess food.
Natural Diet in Your Tank
In a mature tank, shrimp get 70-80% of their nutrition from:
- Biofilm: Microscopic layer on all surfaces
- Algae: Including types invisible to us
- Detritus: Decomposing plant matter
- Microorganisms: Tiny creatures in moss and substrate
This is why tank maturity matters so much. A new tank lacks these food sources.
Supplemental Feeding Schedule
Less is more with cherry shrimp feeding. Here's what works:
Feeding Rule: Only feed what shrimp can consume in 2-3 hours. Remove uneaten food to prevent water quality issues.
New Tank (under 3 months old): Feed every other day
Mature Tank (3+ months): Feed 2-3 times per week
Heavily Planted Mature Tank: Feed 1-2 times per week
Best Foods for Cherry Shrimp
- Specialized shrimp pellets: Hikari Shrimp Cuisine, Shrimp King products
- Blanched vegetables: Zucchini, spinach, cucumber (remove after 24 hours)
- Algae wafers: Break into small pieces
- Leaf litter: Indian almond leaves, oak leaves
- Powdered foods: Bacter AE, SL-Aqua Magic Powder (for babies)
I rotate between 2-3 food types to provide variety. A $15 container of shrimp food lasts 6+ months.
⚠️ Important: Never feed fish food containing copper sulfate. Check ingredients - copper is toxic to all invertebrates.
Cherry Shrimp Breeding Guide
Quick Answer: Cherry shrimp breed easily in stable conditions, with females carrying 20-30 eggs for 30 days before releasing fully-formed baby shrimp.
My shrimp started breeding when I stopped trying so hard. After months of "perfect" conditions with no breeding, I got busy and neglected the tank for three weeks. Came back to find 20+ babies.
The Breeding Process
- Sexual Maturity: Reached at 2-3 months old
- Saddle Development: Yellow eggs visible behind female's head
- Molting: Female molts and releases pheromones
- Mating: Males frantically swim seeking the female
- Berried Female: Fertilized eggs carried under tail
- Hatching: 30 days later, 20-30 shrimplets emerge
Berried: Term for female shrimp carrying eggs under her tail, resembling a cluster of berries.
Breeding Success Factors
Temperature: 72-75°F optimal for breeding activity.
Male to female ratio: 1:2 or 1:3 works best.
Colony size: Minimum 10 shrimp to avoid inbreeding.
Tank maturity: 3+ month old tanks have highest breeding success.
Caring for Baby Shrimp (Shrimplets)
Shrimplets are fully formed miniature versions of adults, about 1-2mm long.
Special Care Needs:
- Sponge filter mandatory (prevents sucking up babies)
- Powdered food helps survival rate
- Dense moss provides hiding spots from adults
- No special parameters needed if adults are thriving
Survival rate is typically 50-70% in first month. Don't panic if you see fewer babies over time - this is normal.
✅ Pro Tip: Java moss is crucial for baby survival. They hide in it and feed on the microorganisms. No moss = much lower survival rates.
Managing Population Growth
A single berried female can start a population explosion. My 10 shrimp became 100+ within 6 months.
Population Control Options:
- Reduce feeding to slow breeding
- Lower temperature to 68-70°F
- Sell or give away excess shrimp
- Add shrimp-safe fish that eat some babies
Troubleshooting Common Cherry Shrimp Problems
Quick Answer: Most cherry shrimp problems stem from water quality issues, temperature shock, or tank immaturity, with 30-50% of beginners losing their first colony within 72 hours.
Let me share solutions to problems that killed my shrimp, so you don't repeat my mistakes.
Mass Die-Off in First 72 Hours
This devastated me three times before I figured it out.
Causes:
- Tank too new (under 3 months old)
- Improper acclimation
- Temperature shock during transport
- Drastically different water parameters
Prevention Protocol:
- Tank Age: Wait minimum 3 months after cycling
- Drip Acclimation: 2-3 hours minimum, not 30 minutes
- Temperature Match: Float bag 30 minutes first
- Test Source Water: Ask seller for their parameters
Emergency Response: If shrimp start dying, immediately test parameters, do a small (10%) water change with aged water, add an airstone for oxygen, and stop all feeding.
Shrimp Losing Color
My fire red shrimp turned pale pink after two weeks. Here's why:
Common Causes:
- Stress from parameter changes
- Light substrate (they pale to blend in)
- Poor diet lacking carotenoids
- Genetics reverting in mixed grades
Solutions:
- Use dark substrate or background
- Feed color-enhancing foods with carotenoids
- Maintain stable parameters
- Separate grades to prevent interbreeding
Failed Molts (White Ring of Death)
A white ring around the shrimp's middle means a failed molt, usually fatal.
Molting: Process where shrimp shed their exoskeleton to grow. Happens every 3-4 weeks in adults.
Prevention:
- Maintain GH 6-8 for proper shell development
- Add calcium sources (cuttlebone, crushed coral)
- Avoid large water changes that trigger premature molting
- Feed varied diet including calcium-rich foods
Shrimp Not Breeding
If your shrimp aren't breeding after 2-3 months, check these factors:
| Issue | Solution |
|---|---|
| All same gender | Females are larger with curved underbelly |
| Too young | Wait until 3+ months old |
| Stressed | Check parameters, reduce changes |
| Overfeeding | Reduce feeding to 2x per week |
| Temperature too low | Raise to 72-75°F |
| Not enough hiding spots | Add more plants and moss |
Bacterial Infections
Milky or opaque appearance in shrimp indicates bacterial infection, often fatal.
Prevention is only option:
- Remove dead shrimp immediately
- Don't overfeed
- Maintain good water quality
- Quarantine new additions
Medications that treat bacterial infections usually contain copper and kill shrimp. Prevention through good husbandry is your only defense.
Cherry Shrimp Tank Mates
Quick Answer: Cherry shrimp thrive alone or with small, peaceful fish like ember tetras and otocinclus, but avoid any fish large enough to eat adult shrimp.
I learned the hard way that "peaceful" doesn't mean "shrimp-safe." My "peaceful" guppies ate $60 worth of shrimp in one week.
Truly Safe Tank Mates
After extensive testing (and losses), these are genuinely safe:
- Otocinclus catfish: Strictly herbivore, ignores shrimp
- Ember tetras: Tiny mouths can't eat adult shrimp
- Pygmy corydoras: Bottom dwellers, peaceful
- Nerite snails: Great algae eaters, won't compete
- Other Neocaridina shrimp: Different colors can be mixed
Risky But Possible
These might work with heavy plant cover and well-fed fish:
- Chili rasboras: Very small, usually safe
- Celestial pearl danios: May eat babies only
- Endler's livebearers: Smaller than guppies
- Clown killifish: Surface dwellers, usually ignore shrimp
Success depends on individual fish personality and hunger levels. Always have backup plans.
Never Keep With Cherry Shrimp
These will eat your shrimp, regardless of what anyone says:
- Bettas: Will hunt and eat all shrimp eventually
- Angelfish: Shrimp are expensive snacks
- Guppies: Seem safe but aren't
- Any cichlids: Even dwarf cichlids eat shrimp
- Gouramis: All species will eat shrimp
- Goldfish: Will eat anything that fits in mouth
⚠️ Important: Even "safe" fish will eat baby shrimp. If breeding is your goal, keep a shrimp-only tank.
Benefits of Shrimp-Only Tanks
After trying community tanks, I now keep dedicated shrimp tanks. Here's why:
- Maximum breeding success
- Can see natural behaviors
- Easier parameter management
- No competition for food
- Lower bioload

Frequently Asked Questions
Are cherry shrimp hard to care for?
Cherry shrimp are easy to care for once established, but require patience initially. The key is starting with a mature tank (3+ months old) rather than newly cycled. With stable parameters and minimal intervention, they're very forgiving.
How many cherry shrimp should I start with?
Start with 10-20 shrimp to establish a breeding colony and avoid inbreeding. This costs $20-50 for basic grades. More shrimp also means better algae control and more interesting behavior to observe.
Can cherry shrimp live in unheated tanks?
Yes, cherry shrimp can live in unheated tanks if room temperature stays between 65-80°F. However, temperature stability is crucial - daily swings over 2-3°F cause stress. Breeding slows below 70°F.
Why are my cherry shrimp dying?
Common causes include new tank syndrome (tank under 3 months old), temperature shock, copper exposure from medications, or parameter swings from large water changes. Check ammonia/nitrite levels immediately and review recent tank changes.
Do cherry shrimp need special substrate?
Cherry shrimp don't need special substrate, but dark colors enhance their red coloration. Fine gravel or sand works well. Avoid sharp substrates that could damage their bodies when foraging.
How long do cherry shrimp live?
Cherry shrimp typically live 1-2 years in aquariums. Higher temperatures (78-80°F) increase metabolism and shorten lifespan to about 1 year, while cooler temperatures (68-72°F) can extend life closer to 2 years.
Can I keep different colored Neocaridina together?
Yes, but they'll interbreed and offspring will eventually revert to wild brown coloration within a few generations. Keep color varieties separate if you want to maintain pure lines. Mixing creates 'Skittles' tanks with various colors.
Final Thoughts on Cherry Shrimp Care
Cherry shrimp taught me patience in this hobby. After losing three colonies worth $150+, I finally understood that success comes from working with nature, not forcing it.
The single most important lesson? Tank maturity beats everything else. That 3-6 month waiting period isn't optional - it's the foundation of success.
Start with a 10-gallon tank, add plants (especially java moss), and let it mature for at least 3 months. Then add 10-15 basic grade cherry shrimp. Feed sparingly, change water minimally, and let them do their thing.
Within 6 months, you'll have a thriving colony that practically manages itself. The shrimp that seemed so fragile at first become surprisingly resilient once established.
Remember: every experienced shrimp keeper has killed shrimp. The difference is we learned from those losses. Now you can learn from mine instead.
