Do I Need to Feed Cleaner Shrimp? A Definitive Guide
The answer is often yes. While cleaner shrimp are known for consuming parasites and algae, relying solely on these sources is usually insufficient, and supplemental feeding is generally required to ensure their long-term health and well-being in a reef tank environment.
Introduction: Understanding Cleaner Shrimp Nutrition
Cleaner shrimp are a fascinating and beneficial addition to any saltwater aquarium, especially reef tanks. Their natural inclination to pick parasites and dead tissue from fish makes them valuable members of the aquarium ecosystem. However, a common misconception is that these industrious invertebrates can thrive solely on what they scavenge. Do I need to feed cleaner shrimp? This article explores the nutritional needs of these creatures and explains why supplemental feeding is usually necessary for optimal health and longevity.
The Natural Diet of Cleaner Shrimp
In their natural habitat, cleaner shrimp, like the Lysmata amboinensis (Skunk Cleaner Shrimp) and Lysmata debelius (Blood Red Fire Shrimp), have a diverse diet. This diet includes:
- Parasites removed from fish
- Algae growing on rocks and surfaces
- Small invertebrates found in the reef environment
- Detritus and decaying organic matter
While they actively seek out these food sources, the availability of each within a captive aquarium environment is often limited and unpredictable.
The Limitations of Scavenging in Aquariums
Aquarium environments, even well-established reef tanks, rarely replicate the abundance and diversity of food found in the ocean. Here’s why cleaner shrimp often need supplemental feeding:
- Limited Parasite Load: A healthy aquarium should ideally have minimal parasites. If cleaner shrimp rely solely on parasites, they will quickly exhaust this food source.
- Algae Control: Many aquarists actively control algae growth, reducing the availability of this food source for cleaner shrimp.
- Competition: Other invertebrates and fish may compete for available food, leaving cleaner shrimp with insufficient resources.
- Nutritional Deficiencies: Relying only on what they scavenge might lead to deficiencies in essential nutrients.
Benefits of Supplemental Feeding
Providing supplemental food to your cleaner shrimp offers several advantages:
- Improved Health: A well-nourished cleaner shrimp is more resistant to disease and lives longer.
- Enhanced Coloration: Proper nutrition contributes to vibrant coloration.
- Increased Activity: Well-fed cleaner shrimp are more active and efficient in their cleaning duties.
- Reduced Cannibalism: Ensuring adequate food reduces the likelihood of cleaner shrimp preying on smaller invertebrates or even each other.
How to Feed Your Cleaner Shrimp
Feeding cleaner shrimp is relatively simple. Here are some guidelines:
- Food Options: Offer a variety of foods, including frozen mysis shrimp, brine shrimp, chopped seafood (squid, shrimp, fish), and sinking pellets or wafers designed for invertebrates.
- Feeding Frequency: Feed small amounts every 2-3 days. Observe your shrimp to gauge their appetite and adjust accordingly.
- Targeted Feeding: Use a turkey baster or pipette to deliver food directly to the shrimp, especially if you have fast-feeding fish that might outcompete them.
- Observation: Monitor your shrimp for signs of healthy appetite and coloration.
Common Mistakes to Avoid
- Overfeeding: Overfeeding can lead to poor water quality and algae blooms.
- Insufficient Feeding: Underfeeding can result in malnutrition and weakened shrimp.
- Ignoring Dietary Needs: Failing to provide a varied diet can lead to nutrient deficiencies.
- Using Poor Quality Food: Use high-quality food specifically formulated for marine invertebrates.
Nutritional Requirements
Cleaner shrimp need a balanced diet consisting of:
- Protein: Essential for growth and tissue repair.
- Fats: Provide energy and support various bodily functions.
- Carbohydrates: Another source of energy.
- Vitamins and Minerals: Crucial for overall health and immune function. Iodine is particularly important for proper molting.

Water Quality Considerations
Good water quality is crucial for the health of all aquarium inhabitants, including cleaner shrimp. Regular water changes, proper filtration, and maintaining stable parameters are essential. Pay particular attention to:
- Ammonia and Nitrite: These should always be at zero.
- Nitrate: Keep nitrate levels low through regular water changes.
- pH: Maintain a stable pH between 8.1 and 8.4.
- Salinity: Keep salinity consistent, typically around 1.025 specific gravity.
Recognizing Signs of Malnutrition
Being able to identify the signs of malnutrition is crucial for ensuring your cleaner shrimp’s health. Signs include:
- Lethargy: A lack of energy and reduced activity.
- Pale Coloration: Faded or dull coloration.
- Difficulty Molting: Problems shedding their exoskeleton.
- Reduced Appetite: Loss of interest in food.
- Thin Body: Noticeably diminished body mass.
Compatibility with Other Tank Inhabitants
Consider the compatibility of cleaner shrimp with other tank inhabitants. Some fish, such as large predatory species, may view cleaner shrimp as food. Always research the compatibility of any new additions to your aquarium.
Frequently Asked Questions (FAQs)
Will cleaner shrimp starve if I don’t feed them?
Yes, it’s highly likely that cleaner shrimp will eventually starve if you rely solely on their cleaning duties and scavenging within the aquarium. While they consume parasites and algae, this often isn’t enough to meet their nutritional needs. Supplemental feeding is crucial for their long-term survival and health.
How often should I feed my cleaner shrimp?
A good starting point is to feed your cleaner shrimp every 2-3 days. Observe their behavior and adjust the frequency based on their appetite. If they readily consume the food, you can feed them more frequently. If they ignore it, reduce the amount or frequency.
What is the best food to feed cleaner shrimp?
Cleaner shrimp thrive on a varied diet. Offer a mix of frozen mysis shrimp, brine shrimp, chopped seafood (squid, shrimp, fish), and sinking pellets or wafers designed for invertebrates. Varying their diet ensures they receive a broad range of nutrients.
Can I overfeed my cleaner shrimp?
Yes, overfeeding is possible and can lead to poor water quality. Only provide the amount of food that your cleaner shrimp can consume within a few minutes. Remove any uneaten food to prevent it from decaying and polluting the water.
Do cleaner shrimp eat algae?
Yes, cleaner shrimp will consume algae, but algae should not be their primary food source. While they might graze on algae, they require a more protein-rich diet.
Are cleaner shrimp reef safe?
Generally, yes, cleaner shrimp are considered reef safe. They don’t typically harm corals or other invertebrates. However, in rare cases, they may nip at corals if they are not receiving enough food. Providing supplemental feeding minimizes this risk.
