Feeding Freshwater Shrimp

Quick Answer

When feeding freshwater shrimp, remember they are natural grazers that spend much of the day eating algae, biofilm, and tiny bits of organic matter. In most aquariums they still need supplemental food several times a week to stay healthy, especially in clean or newly established tanks.

At a Glance

Diet: Omnivore

Best Staple Food: Shrimp pellets or shrimp sticks

Feed: 2–4 times per week

Treat Foods: Blanched vegetables, algae wafers, spinach

Avoid: Overfeeding

What Do Freshwater Shrimp Eat?

Freshwater shrimp naturally feed on:

Biofilm
Soft algae
Decaying plant material
Tiny microorganisms
Organic debris

They spend much of the day searching every surface for food.

Do Shrimp Need Supplemental Feeding?

Yes.

Many beginners assume shrimp can survive only on algae.

While algae and biofilm are important, they rarely provide everything shrimp need over the long term.

Regular supplemental feeding promotes:

Healthy growth
Successful molting
Better breeding
Stronger colors

Best Foods for Freshwater Shrimp

Quality foods include:

Shrimp pellets
Shrimp sticks
Shrimp granules
Algae wafers
Spirulina wafers
Specialized shrimp foods

Choose foods made specifically for freshwater shrimp whenever possible.

Fresh Vegetables

Shrimp often enjoy:

Zucchini
Spinach
Cucumber
Green beans
Carrots (small amounts)

Blanch vegetables briefly so they sink and soften.

Remove leftovers within 12–24 hours.

Natural Foods in the Aquarium

Healthy shrimp tanks usually contain:

Biofilm
Soft algae
Microorganisms
Decaying leaves
Driftwood surfaces

These natural foods are available throughout the day.

A mature aquarium provides much more natural food than a newly set-up tank.

How Often Should You Feed Shrimp?

In a mature aquarium:

Feed supplemental foods 2–4 times each week.

In newer aquariums or breeding colonies:

Small daily feedings may be appropriate if little natural food is available.

Always adjust feeding based on how quickly food disappears.

How Much Should You Feed?

Offer only a small amount.

A piece of shrimp food should normally be consumed within a few hours.

If food remains the next day, reduce the amount at the next feeding.

Foods to Feed Occasionally

Shrimp also enjoy:

Indian almond leaves
Mulberry leaves
Dandelion leaves (chemical-free)
Frozen baby brine shrimp (occasionally)
High-quality protein foods during breeding

Variety supports healthy growth and reproduction.

Calcium and Successful Molting

Shrimp need minerals, especially calcium, to develop strong new shells after molting.

Good water quality and appropriate mineral levels are just as important as feeding.

Never remove a freshly shed shell immediately.

Shrimp usually eat it to recover valuable minerals.

Feeding Shrimp in Community Aquariums

In community tanks, shrimp may compete with:

Tetras
Corydoras
Rasboras
Guppies
Snails

Place food near hiding areas where shrimp feel secure.

Feed after the lights dim if faster fish are eating everything first.

Signs of Overfeeding

Too much food can cause:

Cloudy water
Rising ammonia
Increased nitrate
Pest snails
Planaria
Hydra
Poor water quality

Small portions are always safer.

Signs of Underfeeding

Watch for:

Poor breeding
Slow growth
Pale coloration
Increased competition
Shrimp constantly searching without finding food

Feeding Baby Shrimp

Baby shrimp eat extremely small foods including:

Biofilm
Powdered shrimp foods
Fine algae
Microorganisms

Avoid excessive cleaning of breeding tanks, as biofilm is an important food source for newly hatched shrimp.

Common Feeding Mistakes

Avoid:

Assuming algae is enough
Overfeeding
Leaving vegetables too long
Cleaning away all biofilm
Feeding large portions
Ignoring water quality

Rick’s Experience

Over the years, I found that shrimp colonies did best in mature, stable aquariums where biofilm had plenty of time to develop. While specialty shrimp foods are beneficial, healthy tanks already provide much of what shrimp naturally graze on throughout the day. Small supplemental feedings and excellent water quality consistently produced the healthiest colonies.

Frequently Asked Questions

Can shrimp survive on algae alone?

Usually not. Most shrimp benefit from supplemental feeding several times each week.

How often should I feed Cherry Shrimp?

Most established colonies do well with supplemental feeding 2–4 times weekly.

Do shrimp eat fish food?

Yes. Shrimp often consume leftover fish food, but it should not be their primary diet.

Should I remove uneaten vegetables?

Yes. Remove leftovers within 12–24 hours to prevent water quality problems.

Why do shrimp eat their old shells?

Old shells contain valuable minerals, especially calcium, that help support future molts.

Rick Recommends

Keep these foods available:

Quality shrimp pellets
Shrimp sticks
Spirulina wafers
Algae wafers
Blanched zucchini
Blanched spinach
Indian almond leaves

Rotate foods throughout the week while allowing shrimp to graze naturally between feedings.

Final Thoughts

Freshwater shrimp are easy to feed once you understand their natural grazing behavior. A mature aquarium provides a steady supply of biofilm and algae, but supplemental feeding is still important for long-term health. Feed small amounts, offer a variety of foods, and avoid overfeeding to maintain both healthy shrimp and excellent water quality.
