Freshwater Shrimp Care Sheet

Freshwater Shrimp

This care sheet covers a variety of freshwater shrimp, including: 

 

Overview 

Caridina japonica, Neocaridina denticulata, Neocaridina heteropoda, Necaridina sp., Atyopsis mollucensis, Atya gabonensis, Neocaridina davidi, Palaemonetes paludosus 

A great addition to a freshwater cleaning crew, freshwater shrimp are colorful, interesting little scavengers who can help control algae and uneaten food. These peaceful, community invertebrates need a lot of hiding places and protection from other aquatic life who might try to make a meal out of them, so always do your research to ensure compatibility.

 

Typical appearance and behavior

  • Freshwater shrimp can control algae as well as eat leftover food; in fact, most of their diet consists of algae gathered from the tank, but they will eat almost any food offered 
  • They may feed at night when other fish are less active, and they feel safe enough to roam about  
  • Plants and driftwood are a great addition, giving them plenty of places to hide and a natural food source  
  • Can be kept with some small, nonaggressive fish and some snail species  
  • When they sleep, they will be motionless and unresponsive with a lowered antennae and can sometimes be observed upside down  
  • They come in many colors and patterns with differing levels of care and requirements 
  • Most shrimp are social species and can be found in small to large groups  

 

Characteristics 

Care Difficuty Beginner to advanced, depending on species
Average Life Span Up to 3 years with proper care, depending on species
Average Adult Size 1–6”, depending on species
Diet Omnivorous
Minimum Habitat Size 5+ gallons
Water temperature 72–82°F, depending on species; some may prefer temperatures outside these parameters

 

Habitat 

Habitat size

Keep in an appropriately sized aquarium based on the species selected, which can range from 5+gallons for a few freshwater shrimp to a much larger aquarium for a bigger group of freshwater shrimp. Remember water conditions can change rapidly in smaller water volumes.

Building your habitat

  • Water health - 
    • Provide proper filtration to ensure optimal water quality to help maintain health 
    • Provide slow to moderate water circulation to mimic the water currents and high oxygen levels found in a freshwater shrimp’s natural habitat  
    • Stable water quality (pH, ammonia, nitrate, nitrite) and water temperature are critical to the health of aquatic life; if you are unsure of your water quality, bring a sample to Petco for free testing 
    • Use an aquatic heater to stabilize water temperature, ensuring it does not fluctuate more than 2 degrees in either direction in a 24-hour period 
    • Many freshwater shrimp will benefit from the addition of freshwater salt to the aquarium; the specific gravity should be kept at 1.004 
    • Always research your species-specific needs before adding freshwater aquarium salt, and do not allow specific gravity to fluctuate more than 0.001 in either direction in a 24-hour period. 
  • Décor - 
    • Provide plenty of space for swimming as well as plants, driftwood rocks or décor for hiding places 

 

What to freshwater shrimp eat?

A well-balanced freshwater shrimp diet consists of: 

  • Flakes, pellets, freeze-dried, frozen foods, algae sheets and wafers 

Things to remember when feeding your freshwater shrimp: 

  • They typically feed on algae and leftover foods but should be offered supplemental feedings 2–3 times per week 
  • Thaw frozen food before feeding 

 

Freshwater shrimp care 

  • Maintaining great water quality with regular water changes and adequate filtration is important to help keep your freshwater shrimp healthy 
    • Daily: Check filter, water temperature and other equipment 
    • Weekly: Test water quality at least once a week 
    • Weekly to monthly: Change 10–25% of the total volume of water every 2–4 weeks, or as needed; change filter media monthly 
  • Avoid overcrowded conditions, which are a major cause of stress and disease
