Bamboo Shrimp vs. Vampire Shrimp: Choosing the Best Gentle Giant for Your Aquarium
A Guide to Freshwater Filter-Feeding Shrimp: Care, Compatibility, and Choosing the Right Species for Your Tank
Filter-feeding shrimp are some of the most fascinating additions to a freshwater aquarium. Unlike scavenger shrimp that forage on the substrate, these unique shrimp use feathery appendages to catch microscopic particles from the water column. Two of the most popular species in the hobby are the Bamboo Shrimp (Atyopsis moluccensis) and the Vampire Shrimp (Atya gabonensis)—both peaceful, beneficial, and visually striking in their own ways.
But which one is right for your aquarium? In this guide, we’ll compare their care needs, tank requirements, pros and cons, and best (and worst) tank mates to help you decide.
Meet the Filter Feeders
Bamboo Shrimp (Atyopsis moluccensis)
A young Bamboo Shrimp (Atyopsis moluccensis) from the freshwater streams of Southeast Asia clings to a rock, preparing to filter-feed. As they grow, their feathery appendages develop fully, allowing them to expertly capture tiny food particles from the water current.
Also known as Wood Shrimp, this species originates from Southeast Asia and thrives in moderate to high-flow waters. Their coloration varies from reddish-brown to tan with subtle striping, helping them blend into driftwood and plants. They’re highly active, often seen perching in strong currents with their fan-like appendages spread wide to collect floating food particles.
✅ Pros:
- Highly active and fun to watch.
- Easy to find in the aquarium trade.
- Can coexist well with other peaceful tank mates.
❌ Cons:
- More vulnerable to starvation if food isn't available in the water column.
- Requires a steady water flow for feeding.
- Does best in well-established tanks with natural micro-foods.
Vampire Shrimp (Atya gabonensis)
A Vampire Shrimp (Atya gabonensis) perches on a rock, extending its chelipeds—specialized fan-like appendages—to capture microscopic food particles from the water. Native to West Africa and South America, these gentle giants rely on strong water flow to bring a steady supply of organic matter to their feathery fans.
Despite their name, Vampire Shrimp are completely peaceful and much larger than Bamboo Shrimp, growing up to 6 inches. Their colors range from blue and gray to shades of purple and brown, and they often shift hues based on mood or environment. Vampire Shrimp are more reclusive, preferring to hide under rocks or driftwood, only emerging when they feel safe.
✅ Pros:
- Longer lifespan (up to 10 years).
- Unique coloration that changes over time.
- Hardy once established in a stable aquarium.
❌ Cons:
- More difficult to find in the aquarium trade.
- Often hides and is less active than Bamboo Shrimp.
- Requires an even larger tank (30+ gallons recommended).
Setting Up the Ideal Aquarium
Since both species rely on floating food particles, the right tank setup is essential to keeping them healthy.
Tank Size & Water Parameters:
| Requirement | Bamboo Shrimp | Vampire Shrimp |
|---|---|---|
| Tank Size | 20+ gallons | 30+ gallons |
| Temperature | 72°F - 82°F (22°C - 28°C) | 72°F - 82°F (22°C - 28°C) |
| pH | 6.5 - 7.5 | 6.8 - 7.5 |
| Water Flow | Moderate to strong | Moderate to strong |
| Lifespan | ~4 years | Up to 10 years |
Both shrimp depend on water currents to bring food to them. Using a sponge filter, HOB filter, or a powerhead can help maintain the right level of flow. However, avoid overly powerful currents that could push them around.
Plants & Hardscape:
A planted tank with natural biofilm provides an extra food source and hiding spots. Good options include:
✅ Plants: Java Fern, Anubias, Water Sprite, and mosses.
✅ Hardscape: Driftwood, rock caves, and ledges for perching.
✅ Botanicals: Indian Almond Leaves or alder cones can release beneficial tannins.
Best & Worst Tank Mates
Because they are completely peaceful and non-aggressive, filter-feeding shrimp need compatible tank mates that won’t harm or outcompete them.
✅ Good Tank Mates:
- Peaceful schooling fish: Tetras, Rasboras, Harlequin Rasboras, and smaller Rainbowfish.
- Bottom dwellers: Corydoras Catfish and Otocinclus.
- Other shrimp species: Amano Shrimp, Neocaridina Shrimp, and Caridina Shrimp.
- Snails: Mystery Snails, Nerite Snails, and Rabbit Snails.
❌ Tank Mates to Avoid:
- Aggressive fish: Cichlids (like Oscars and Jack Dempseys), large Gouramis, and aggressive Barbs.
- Fast-swimming or nippy fish: Bettas, larger Danios, or any fish that might outcompete them for food.
- Crayfish and large predatory invertebrates: Crayfish may see them as food.
- Goldfish: Too messy and may outcompete them for food.

These social shrimp often cluster in prime feeding spots, taking advantage of the floating debris in the water column.
Diet & Feeding: Keeping Them Well-Fed
Since filter-feeding shrimp don’t pick up food from the substrate, they rely entirely on food particles in the water. To keep them healthy, offer:
✅ Fine-particle foods like:
- Crushed flake food or powdered fish food.
- Microscopic algae and biofilm.
- Small, suspended particles from sinking foods.
- Natural detritus and microorganisms in well-established tanks.
💡 Pro Tip: Turn off filters or powerheads for 10-15 minutes when feeding to prevent food from being pushed away too quickly.
Common Mistakes & Troubleshooting
🚨 Mistake #1: Adding Them to a New Tank Too Soon
- These shrimp need an established tank (6+ months old) with natural microorganisms for them to graze on.
🚨 Mistake #2: Not Enough Food in the Water
- If they are constantly moving around the tank with their fans closed, they may not be finding enough food.
🚨 Mistake #3: Keeping Them in a Low-Flow Tank
- Without moderate to strong water movement, they won’t be able to filter-feed efficiently.
🚨 Mistake #4: Molting Issues
- Avoid large water changes that alter water parameters too quickly.

The coloration of Vampire Shrimp can change over time due to diet, with different algae and organic matter influencing their hues, ranging from blue and gray to purple and brown.
Q&A: Everything You Need to Know About Filter-Feeding Shrimp
Q: Can Bamboo Shrimp and Vampire Shrimp live together?
A: Yes! They can coexist peacefully if there’s enough food in the water column. Multiple perching spots help prevent competition.
Q: Do filter-feeding shrimp eat algae?
A: No, they rely on suspended food particles and do not actively graze on algae like Amano Shrimp.
Q: Why is my Bamboo Shrimp turning pale?
A: A pale color can indicate stress, molting, or poor water quality. Ensure stable conditions and a good food supply.
Q: How long do Bamboo and Vampire Shrimp live?
A: Bamboo Shrimp live around 4 years, while Vampire Shrimp can live up to 10 years.
Q: How do I know if my shrimp is getting enough food?
A: If they keep their feeding fans closed often, they may not be getting enough suspended food.
Q: Can they survive in a low-flow tank?
A: No, moderate to strong water flow is necessary for them to feed properly.
Q: How often do filter-feeding shrimp molt?
A: Adults molt every few months, while younger shrimp molt more frequently.
Q: Do they reproduce in freshwater tanks?
A: No, their larvae require brackish or saltwater to develop.
Q: Why is my Vampire Shrimp always hiding?
A: They are naturally nocturnal and prefer to stay hidden during the day.
Q: What should I do if my shrimp stops eating?
A: Check water flow, food availability, and tank conditions to ensure their needs are met.
Final Thoughts
Bamboo Shrimp are great for active aquariums, while Vampire Shrimp are perfect for those who appreciate unique, long-lived inverts. Both offer natural water filtration and are a peaceful addition to planted tanks.
