1. Origin, History, and Appearance
Origin & Natural History
Freshwater shrimp species originate from various regions worldwide, with the most popular aquarium species coming from Asia, South America, and Africa. They inhabit rivers, streams, lakes, and even brackish water environments. The two most commonly kept genera in the aquarium hobby are:
Neocaridina – Includes the widely popular Cherry Shrimp (Neocaridina davidi), originally found in Taiwan and China.
Caridina – Includes Crystal Shrimp and Bee Shrimp, which are native to Southeast Asia.
Amano Shrimp (Caridina multidentata) – Found in Japan and Taiwan.
Ghost Shrimp (Palaemonetes sp.) – Found in North and South America.
Shrimp have been kept in aquariums for decades, but the selective breeding of colorful strains has exploded in popularity in recent years.
Appearance
Size: Typically between 1–2 inches (2.5–5 cm)
Body Shape: Elongated body with jointed legs, two long antennae, and a segmented tail
Colors: Ranges from transparent to bright red, blue, yellow, green, black, and white, depending on the species
Distinguishing Features: Many species have striping, spots, or gradient coloration that enhances their appearance in aquariums
2. Varieties & Selective Breeding
Natural Variants
Wild Neocaridina Shrimp – Typically brown or green, well-camouflaged in their natural environment
Wild Caridina Shrimp – Mostly clear with minor markings
Selective Breeding Variants
Over time, shrimp breeders have developed highly vibrant and unique color variations, including:
Neocaridina Varieties
Red Cherry Shrimp – Most common, bright red
Blue Dream Shrimp – Deep blue coloration
Yellow Golden Back Shrimp – Neon yellow with a golden stripe
Green Jade Shrimp – Unique green hue
Rili Shrimp – Semi-transparent with colored bands
Caridina Varieties
Crystal Red Shrimp (CRS) – White and red striped
Crystal Black Shrimp (CBS) – Black and white variation
Taiwan Bee Shrimp – Unique patterns, including Blue Bolt and Panda
Shadow Panda Shrimp – Deep black with ice-blue highlights
3. Natural Habitat & Food in the Wild
Habitat
Shrimp thrive in slow-moving, heavily planted areas with ample hiding spots, soft leaf litter, and natural biofilm. They are often found in:
Shallow freshwater streams with a mix of sand, rocks, and organic debris
Blackwater environments rich in tannins
Brackish estuaries (Amano shrimp larvae require brackish water to develop)
Diet in the Wild
Shrimp are scavengers and detritivores, meaning they eat:
Biofilm & algae – Their primary food source
Decaying plant matter – Such as fallen leaves
Microorganisms & tiny invertebrates – Found in natural water sources
4. Tank Size
Minimum tank size: 5 gallons (for a small shrimp colony)
Ideal tank size: 10+ gallons (for larger colonies)
Shrimp thrive in larger, stable environments with consistent water conditions
5. Water Parameters
| Shrimp Type | Temperature (°C) | pH | GH (Hardness) | KH (Hardness) | TDS (ppm) |
|---|---|---|---|---|---|
| Neocaridina Shrimp (Cherry Shrimp, Blue Dream, etc.) | 20–25°C (68–77°F) | 6.5–7.5 | 6–8 | 2–4 | 200–300 |
| Caridina Shrimp (Crystal Shrimp, Taiwan Bee Shrimp, etc.) | 20–23°C (68–74°F) | 5.5–6.5 | 4–6 | 0–2 | 100–200 |
| Amano Shrimp & Ghost Shrimp | 18–26°C (64–79°F) | 6.5–7.5 | 6–8 | 2–4 | - |
6. Natural Behavior & In-Tank Behavior
Peaceful and social – Shrimp do best in groups of 10+
Constant grazers – Always searching for biofilm and algae
Skittish when alone – Tend to hide more if kept in low numbers
Active at dawn and dusk – More movement during low light periods
7. Tank Setup & Décor
Best Environment for Shrimp
Substrate: Dark sand or fine gravel to mimic natural conditions
Live Plants: Mosses (Java moss, Christmas moss), ferns, floating plants
Decor: Driftwood, cholla wood, and almond leaves to promote biofilm growth
Filtration: Sponge filters to avoid sucking up shrimp
8. Life Span & Growth Rate
Lifespan: 1.5–2 years (up to 3 years with optimal care)
Growth Rate: Juveniles reach adulthood in 3–4 months
9. Ideal Tank Mates
Best Tank Mates
Small peaceful fish: Neon Tetras, Rasboras, Otocinclus
Bottom-dwellers: Corydoras, small loaches
Other invertebrates: Snails (Mystery, Nerite, Ramshorn)
Tank Mates to Avoid
Aggressive fish: Cichlids, Angelfish, Bettas
Predators: Goldfish, larger Gouramis
Fast-moving fish: Barbs (may stress or eat shrimp)
10. Common Diseases & Problems
Bacterial infections: White patches, lethargy
Parasitic infections: Internal parasites, Vorticella (white fuzz)
Molting issues: Caused by improper water parameters or calcium deficiency
Prevention & Treatment
Maintain stable water conditions
Offer calcium sources (cuttlefish bone, mineral blocks)
Quarantine new shrimp before adding them to the main tank
11. Best Food in Captivity
To ensure optimal health, growth, and molting for shrimp in captivity, it's essential to provide a well-balanced diet with the right nutrients.
-
Life Aayu Shrimp Regular Food – A specially formulated daily diet that promotes shrimp growth and enhances color. Made with high-quality ingredients like fish meal, shrimp meal, spirulina, and astaxanthin, it supports strong immune function and improves molting cycles.
-

-
Blanched Vegetables – Occasional feeding of softened zucchini, spinach, and pumpkin can provide additional fiber and nutrients to complement the shrimp’s diet.
-
Protein Supplements – Bloodworms can be offered occasionally, especially for Amano shrimp, to fulfill their protein needs.
Feeding Schedule
Feed 2–3 times a week in small portions
Remove uneaten food after 2 hours
12. Male & Female Differences
Males: Smaller, slimmer, less colorful
Females: Larger, rounder belly, more intense coloration
13. Breeding
Neocaridina: Easily breed in freshwater
Caridina: Require specific pH and softness
Amano: Larvae need brackish water to develop
14. Coloration & Mood Changes
Faded colors = stress or poor water quality
Brighter colors = good health and breeding readiness
15. Unique Aspects & Additional Tips for Fishkeepers
Shrimp are sensitive to copper, so avoid medications with copper sulfate.
Mature tanks with established biofilm are best for shrimp colonies.
Keeping a shrimp-only tank ensures the best survival rates.
