Will Shrimp Eat Fish Eggs? Here’s What Every Aquarium Owner Needs to Know

Post date |

As an experienced aquarium keeper, I’ve seen this question pop up countless times in our community. The short answer? Yes, shrimp will eat fish eggs – but there’s more to this story than meets the eye.

The Truth About Shrimp and Fish Eggs

Let me break down what I’ve learned from years of keeping shrimp and breeding fish:

The Good, The Bad, and The Shrimpley

  • Cherry shrimp and Amano shrimp are known egg-eaters when given the chance
  • Shrimp will especially target undefended or unfertilized eggs
  • Some aquarists actually USE shrimp to keep fish eggs clean from fungus
  • Different shrimp species have different behaviors around eggs

Real-World Examples

In my 10-gallon planted tank, I’ve witnessed firsthand how shrimp interact with fish eggs. Here’s what typically happens

Otocinclus Breeding Experience

  • Eggs often disappear overnight when left unprotected
  • Survival rates drop significantly in tanks with high shrimp populations
  • Eggs laid on plant undersides (especially Cryptocoryne wendtii) are common targets

Corydoras Breeding Scenario

  • Cherry shrimp have been observed actively eating Corydoras eggs
  • Some hobbyists use breeder boxes to protect eggs
  • Unfertilized eggs are particularly vulnerable

The Double-Edged Sword: Shrimp as Egg Caretakers

Here’s something interesting – shrimp aren’t always the bad guys! Some benefits include:

  1. Fungus Prevention

    • Shrimp clean eggs of harmful fungus
    • They remove dead or unfertilized eggs
    • This can actually increase overall survival rates
  2. Controlled Environment

    • Many breeders use cherry shrimp specifically for egg maintenance
    • Works best when shrimp are well-fed
    • Requires careful monitoring

How to Protect Your Fish Eggs

Wanna breed fish successfully with shrimp around? Try these tips:

Prevention Methods

  1. Use breeding boxes or separate tanks
  2. Keep your shrimp well-fed
  3. Remove eggs to dedicated hatching tanks
  4. Monitor egg locations carefully

Feeding Schedule

  • Offer food every 1-2 days
  • Include variety:
    • Algae wafers
    • Sinking shrimp pellets
    • Blanched vegetables
    • Commercial fish food

Species-Specific Behavior

Different shrimp types show varying tendencies

Cherry Shrimp (Neocaridina)

  • Generally opportunistic egg-eaters
  • More likely to eat eggs if underfed
  • Can be useful for egg maintenance if managed properly

Amano Shrimp

  • More aggressive egg-hunters
  • Should be kept separate from breeding fish
  • Excellent algae eaters but risky around eggs

Success Stories and Warnings

From my experience running a community tank:

What Works:

  • Dedicated breeding tanks
  • Regular feeding schedule
  • Proper hiding spots for eggs
  • Monitoring water parameters

What Doesn’t:

  • Mixing breeding fish with hungry shrimp
  • Leaving eggs unprotected
  • Irregular feeding schedules
  • Overcrowded tanks

Final Thoughts

Look, keeping shrimp with breeding fish ain’t always easy. But with proper planning and management, it’s totally doable. Just remember

  • Keep your shrimp well-fed
  • Use breeding boxes when necessary
  • Monitor your tank regularly
  • Consider separate breeding tanks for valuable spawns

I’ve learned these lessons the hard way, and I hope sharing them helps you avoid the same mistakes. Whether you’re a beginner or experienced aquarist, understanding these dynamics is crucial for successful breeding.

Remember, every tank is different, and what works in one setup might not work in another. Don’t be afraid to experiment and find what works best for your aquatic friends!

Pro Tip

If you’re serious about breeding fish, consider setting up a dedicated breeding tank. It’s easier than trying to manage complex relationships between different species in a community tank.

Stay fishy, friends!

Why the Mediterranean diet?

Diet is known to have an effect on long-term diseases. These include heart and blood vessel problems known as cardiovascular disease. Observations from a study in the 1960s found that cardiovascular disease was linked to fewer deaths in some Mediterranean countries, such as Greece and Italy, than in the U.S. and northern Europe.

More-recent studies linked the Mediterranean diet with lower risk factors for heart disease, such as high cholesterol and high blood pressure.

Today, the Mediterranean diet is one of the healthy eating plans that American nutrition experts recommend. Its also recognized by the World Health Organization as a healthy-eating pattern.

Many cultures have eating patterns similar to the Mediterranean diet, including Japan, for example.

And other diets have some of the same recommendations as the Mediterranean diet. Two examples are the Dietary Approaches to Stop Hypertension (DASH) diet, and the Dietary Guidelines for Americans.

Research suggests that its key to follow the Mediterranean diet over the long term for your heart to benefit.
