Freshwater Shrimp Care — Cherry, Crystal & Amano
Colourful, endlessly entertaining and superb cleaners, freshwater shrimp are perfect for nano tanks. Learn to set up, feed, breed and protect a thriving shrimp colony.
Why Keep Freshwater Shrimp?
Freshwater shrimp pack an enormous amount of interest into a tiny footprint. A ten-litre planted tank can house a colourful, self-sustaining colony that grazes algae and biofilm all day. They are among the few aquarium animals that will breed reliably for a beginner, turning a handful of starter shrimp into dozens over a few months.
The golden rules of shrimp keeping are simple: a mature stable tank, zero copper, gentle filtration and stable water. Get those right and shrimp are among the most rewarding and low-cost creatures in the hobby.
Popular Shrimp Compared
Start with the forgiving Neocaridina before moving to sensitive Caridina.
| Species | Hardiness | pH | Notes |
|---|---|---|---|
| Cherry Shrimp (Neocaridina) | Very forgiving | 6.5–7.5 | Best beginner shrimp; breeds readily in tap water; comes in red, blue, yellow, green. |
| Amano Shrimp | Very hardy | 6.5–7.5 | Champion algae eater; larger; will not breed in freshwater (larvae need brackish). |
| Crystal / Bee Shrimp (Caridina) | Sensitive | 5.8–6.8 | Stunning red/black or black/white grades; needs soft, remineralised RO water and a mature tank. |
| Ghost Shrimp | Hardy | 7.0–8.0 | Cheap, transparent scavenger; good cleanup crew but can be nippy when hungry. |
Shrimp Tank Setup
Use a Mature, Stable Tank
Shrimp graze on biofilm and are very sensitive to ammonia and copper. Always add shrimp to a fully cycled tank that has been running for at least a few weeks so a healthy layer of microorganisms has developed for them to eat.
Choose a Gentle Sponge Filter
A sponge filter provides biological filtration and grazing surface without sucking in shrimplets. If you use a hang-on-back or canister filter, cover the intake with a fine pre-filter sponge to protect babies.
Add Plenty of Plants and Moss
Java moss, anubias and floating plants give shrimp cover, grazing surface and breeding sites. A heavily planted tank dramatically increases survival of young shrimp.
Keep Parameters Stable
Shrimp handle a range of values but hate sudden swings. Drip-acclimate new shrimp slowly over an hour, and avoid large or abrupt water changes. Never use medications or plant fertilisers containing copper.
Shrimp-Killing Mistakes
Avoid these four and your colony will flourish.
Adding Shrimp to a New Tank
A tank that is not fully cycled and matured has ammonia spikes and little biofilm. Shrimp added too early starve or are poisoned. Patience is the number-one shrimp-keeping skill.
Copper Exposure
Many fish medications, some plant fertilisers and certain tap water sources contain copper, which is lethal to invertebrates. Always check labels and treat shrimp tanks as copper-free zones.
Overfeeding
Shrimp eat constantly from biofilm and need very little supplemental food. Overfeeding fouls the water and causes deadly bacterial blooms. Feed a tiny amount every couple of days and remove leftovers.
Aggressive Tank Mates
Most fish see shrimp — especially babies — as food. Keep shrimp alone or only with tiny peaceful fish like chili rasboras or otocinclus if you want a breeding colony.
Frequently Asked Questions
What is the easiest shrimp for beginners?
Cherry shrimp (Neocaridina davidi) are by far the easiest. They tolerate a wide range of water parameters, breed readily in ordinary dechlorinated tap water, and come in bright colours. Master cherry shrimp before attempting sensitive Caridina species like crystal or bee shrimp.
Do freshwater shrimp need a heater?
Not always. Most popular shrimp are comfortable at typical room temperatures of 20–24 °C. A heater is only needed if your room gets cold, in which case a small adjustable heater keeps the temperature stable. Avoid temperatures above about 26 °C, which shorten shrimp lifespan.
Why do my shrimp keep dying?
The most common causes are an immature or uncycled tank, copper from medications or fertilisers, sudden parameter swings, or too-fast acclimation. Test for ammonia and nitrite, remove any copper sources, drip-acclimate new arrivals slowly, and keep water changes small and gradual.
How do cherry shrimp breed?
In a stable, mature tank cherry shrimp breed on their own. A female carries a clutch of eggs under her tail (called being "berried") for about three to four weeks, then releases fully-formed miniature shrimp. Provide moss and plants for the babies to hide and graze, and keep predators out.
Why is there an empty shell in my tank?
That is a molt, not a dead shrimp. Shrimp shed their exoskeleton as they grow, leaving behind a clear cast. Leave it in the tank — shrimp often eat it to recover calcium. Frequent successful molts are a sign of healthy, growing shrimp.
