Keeping Caridina shrimp is one of the most rewarding experiences in the aquarium hobby. These small, colorful invertebrates — such as Crystal Red Shrimp, Taiwan Bee Shrimp, and Amano Shrimp — are admired for their vivid patterns, delicate appearance, and fascinating behavior.
However, Caridina shrimp care requires careful tank management, and one of the most common questions aquarists ask is: “What fish can live with Caridina shrimp?”
Because of their small size and peaceful nature, Caridina shrimp need compatible tank mates that won’t stress or prey on them. In this guide, we’ll explore the best tank mates for Caridina shrimp, species to avoid, and key tips for maintaining a harmonious shrimp community.

Understanding Caridina Shrimp Behavior
Before choosing tank mates, it’s important to understand how Caridina shrimp behave in aquariums.
- Peaceful and Timid: They’re non-aggressive and easily startled, especially during molting or breeding.
- Small and Vulnerable: Most species grow only 1–1.5 inches long, making them potential prey for larger or curious fish.
- Sensitive to Water Changes: Caridina shrimp prefer stable, soft, and slightly acidic water conditions.
- Algae and Biofilm Feeders: They spend most of their time grazing on surfaces for biofilm, detritus, and algae.
These traits mean only peaceful, small, and calm tank mates can safely share a tank with Caridina shrimp.
Best Tank Mates for Caridina Shrimp
1. Otocinclus Catfish (Otocinclus affinis)
Otocinclus catfish are one of the best and safest tank mates for shrimp. They’re peaceful, small (1–2 inches), and feed exclusively on algae, leaving shrimp completely undisturbed.
Why They Work Well Together:
- Non-aggressive and gentle scavengers
- Help keep the tank clean by grazing on algae
- Thrive in the same soft, acidic water as Caridina shrimp
Care Tips:
Keep them in groups of at least 4–6, and ensure the tank is mature with established algae growth.
2. Pygmy Corydoras (Corydoras pygmaeus)
Pygmy Corydoras are tiny, schooling bottom dwellers that coexist peacefully with shrimp. Their small size and calm behavior make them an excellent choice for shrimp tanks.
Why They Work Well Together:
- Peaceful and shrimp-safe scavengers
- Occupy lower levels without disturbing shrimp colonies
- Prefer similar soft-water parameters
Care Tips:
Keep groups of at least 6 or more for comfort. Avoid larger Corydoras species, as they may accidentally disturb baby shrimp.
3. Kuhli Loach (Pangio kuhlii)
The Kuhli Loach is a slender, eel-like fish that spends most of its time burrowed or scavenging at night. While slightly larger, they’re gentle and rarely bother adult shrimp.
Why They Work Well Together:
- No interest in chasing shrimp
- Active mostly at night, reducing overlap with shrimp activity
- Great at cleaning leftover food without aggression
Care Tips:
Provide soft substrate and hiding spots like caves or driftwood to reduce stress. Avoid if keeping very small baby shrimp in large numbers.
4. Small Schooling Fish (Microrasboras and Ember Tetras)
Tiny, peaceful schooling fish such as Chili Rasboras (Boraras brigittae), Mosquito Rasboras, or Ember Tetras (Hyphessobrycon amandae) can coexist safely with Caridina shrimp.
Why They Work Well Together:
- Too small to harm adult shrimp
- Add movement and color to the aquarium
- Thrive in similar low-pH, soft-water setups
Care Tips:
Keep them in groups of 8–10 or more. Provide dense plant cover so shrimp can retreat during breeding or molting.
5. Snails (Nerite Snails, Mystery Snails, and Ramshorn Snails)
Freshwater Snails are among the most common and compatible tank mates for Caridina shrimp.
Why They Work Well Together:
- Peaceful, algae-eating invertebrates
- Don’t compete with shrimp for food
- Help keep the tank clean and stable
Recommended Species:
- Nerite Snails: Great algae eaters that don’t reproduce in freshwater.
- Ramshorn Snails: Small, colorful, and useful for cleaning glass and decorations.
- Mystery Snails: Larger and peaceful; just ensure there’s enough calcium for shell growth.
6. Amano Shrimp (Caridina multidentata)
If you’re keeping Caridina shrimp species like Crystal Red or Taiwan Bee, you can also house Amano Shrimp in the same tank. They are larger, active cleaners that help manage algae and waste.
Why They Work Well Together:
- Peaceful and non-predatory
- Help control algae and detritus buildup
- Share similar water preferences
Care Tips:
Avoid mixing Amano Shrimp with much smaller shrimplets during breeding stages, as Amanos may outcompete them for food.
Frequently Asked Questions (FAQ)

1. Can I keep Caridina shrimp with Neocaridina shrimp?
Technically yes, but it’s not ideal. They have different water requirements — Caridina prefer soft, acidic water, while Neocaridina thrive in harder, more alkaline conditions. Keeping both in one tank may result in poor health or failed breeding.
2. What is the safest fish to keep with Caridina shrimp?
Otocinclus catfish and Pygmy Corydoras are widely regarded as the safest fish species for Caridina shrimp tanks. They’re peaceful, small, and occupy similar habitats.
3. How many shrimp should I start with?
Start with a group of 10–15 Caridina shrimp to ensure successful breeding and colony growth.
4. Will baby shrimp survive with fish?
In most cases, only adult shrimp will thrive with fish. If breeding is your goal, keep a shrimp-only tank or use dense moss and plants for baby shrimp to hide.
5. Do Caridina shrimp need tank mates?
No. Caridina shrimp can live happily in a shrimp-only setup. However, peaceful tank mates can enhance biodiversity and help maintain balance in the ecosystem.
Conclusion
Choosing the right tank mates for Caridina shrimp ensures a peaceful and thriving community aquarium. Stick to small, non-aggressive species that share similar water conditions — such as Otocinclus catfish, Pygmy Corydoras, Ember Tetras, and Nerite Snails.
Avoid larger or predatory fish, and focus on creating a safe, plant-rich environment with stable water parameters. The result will be a vibrant, balanced ecosystem where your shrimp can breed, graze, and display their best colors naturally.For aquarists who love both fish and shrimp, building a harmonious Caridina shrimp community tank is one of the most satisfying experiences in freshwater aquascaping.
