But the question remains: do mollies eat Shrimp?

In this comprehensive compatibility guide, we will explore the relationship between mollies and Shrimp in a tank environment. We’ll discuss the feeding habits of mollies and how they may impact Shrimp, as well as the potential challenges and benefits of keeping these two species together. 

Whether you’re considering adding mollies or shrimp to your aquarium, or you already have both and are curious about their compatibility, this guide will provide you with valuable insights and practical advice.

By the end of this guide, you’ll have a better understanding of whether mollies and Shrimp can coexist peacefully in the same tank and how to create a harmonious aquatic environment for both species to thrive. 

Do Mollies Eat Shrimp In Aquarium?

Mollies may nibble on baby shrimp or weakened adults, but they’re not dedicated shrimp predators. These omnivorous freshwater fish primarily feed on algae, plants, and flakes, with occasional snacks of insects or worms.

However, the compatibility of mollies and Shrimp depends on several factors:

  • Shrimp species: Larger Shrimp, like Amano shrimp, are less vulnerable than tiny cherry shrimp.
  • Tank size and layout: Densely planted tanks with hiding places like rocks and driftwood provide excellent shrimp refuge.
  • Molly’s temperament: Some individual mollies may be more aggressive than others.

To ensure a harmonious tank:

  • Introduce adult shrimp: They’re less likely to be seen as a live food source.
  • Maintain proper water quality: Good conditions benefit both Shrimp and mollies.
  • Monitor your tank: Keep an eye on the interaction between the species and intervene if necessary.

Ultimately, success depends on creating a balanced environment that caters to the needs of both fish and Shrimp.

Understanding Mollies and Shrimp Compatibility

Mollies and Shrimp can live together in the same aquarium, but it’s important to understand their compatibility to ensure a harmonious tank environment. Mollies are peaceful fish that don’t typically bother Shrimp, making them generally compatible tank mates.

However, it’s important to note that larger mollies may occasionally nip at smaller Shrimp, so it’s best to choose larger shrimp species if you decide to keep them together. It’s also important to provide plenty of hiding spaces and live plants for the Shrimp to retreat to if they feel threatened.

Additionally, it’s important to monitor the water parameters in the fish tank, as Shrimp are sensitive to changes in water quality. Keeping Shrimp and mollies together can be a rewarding experience as both species are visually appealing and come in a variety of colors and patterns. 

Overall, understanding the compatibility between mollies and Shrimp and providing the proper environment for both species can lead to a successful and enjoyable community tank. 

Can Molly Fish And Shrimp Live Together?

Yes, mollies and Shrimp can sometimes live together peacefully, but it’s not without its challenges. Here’s the breakdown:


  • Omnivores primarily eat algae, plants, and flakes.
  • Some may nibble on baby shrimp or weakened adults due to their opportunistic nature.
  • More aggressive individuals pose a greater risk to Shrimp.


  • Vulnerable to predation, especially smaller species like cherry shrimp.
  • Thrive in densely planted tanks with hiding spots like rocks and driftwood.

Factors for success:

  • Shrimp size: Larger Shrimp (Amanos) are less likely to be eaten.
  • Tank size: Larger tanks provide more space and hiding areas.
  • Plant cover: Dense plants offer a crucial refuge for Shrimp.
  • Water quality: Stable conditions benefit both species.
  • Molly temperament: Observe for overly aggressive individuals.

Tips for harmony:

  • Introduce adult shrimp to minimize predation risk.
  • Monitor interaction and be ready to separate if needed.
  • Maintain high quality for optimal health.

Overall, cohabitation requires careful planning and monitoring. With the right setup and responsible fishkeeping practices, mollies and Shrimp can coexist happily in your aquarium.

Remember: The success of this pairing depends on individual circumstances and careful observation. Always prioritize the well-being of both fish and Shrimp.

Can You Keep Molly Fish and Cherry Shrimp in the Same Aquarium?

Yes, it is possible to keep molly fish and cherry shrimp in the same aquarium, but there are a few things to consider. First, molly fish are known to be peaceful and non-aggressive towards other tank mates, making them generally compatible with cherry shrimp.

However, molly fish are omnivores and may eat the occasional shrimp fry, especially if they are hungry or not provided with enough food. It is important to create plenty of hiding spaces, plants, and decorations for the Shrimp to seek refuge and feel safe.

Additionally, it is important to maintain good water quality and provide a well-balanced diet to ensure the health and well-being of both the molly fish and cherry shrimp.

With proper care and attention to their individual needs, these two species can coexist in the same aquarium and create a visually appealing and diverse aquatic environment. 

Do Dalmatian mollies eat Shrimp?

Yes, Dalmatian mollies can eat Shrimp, especially smaller varieties like cherry shrimp or ghost shrimp. They are omnivorous fish with a strong predatory instinct. While their primary diet consists of algae and plant matter, they will readily snack on any meaty morsels they come across, including Shrimp.

However, the likelihood of them actively hunting and eating Shrimp depends on several factors:

  • Shrimp size: Dalmatians are more likely to target smaller Shrimp that fit easily in their mouths. Larger Shrimp, like Amano shrimp, have a better chance of coexisting peacefully with mollies.
  • Tank environment: A densely planted tank with plenty of hiding places can provide refuge for Shrimp and deter mollies from pursuing them. Conversely, a bare tank with minimal cover creates a more exposed environment where Shrimp are more vulnerable.
  • Individuality: Like any animal, each molly has its personality and temperament. Some individuals may be more inclined to predation than others.

So, can Dalmatian mollies and Shrimp live together? Maybe, with some caveats:

  • Choose larger Shrimp: Opt for Amano shrimp, bamboo shrimp, or other robust varieties.
  • Provide ample hiding places: Decorate your tank with rocks, driftwood, and dense plants to offer shrimp shelter.
  • Monitor closely: Keep an eye on your fish and Shrimp to ensure the shrimp aren’t being harassed or picked off.
  • Start with a few Shrimp: If you’re unsure about compatibility, introduce a small group of Shrimp initially and see how it goes.

Ultimately, keeping Dalmatian mollies and Shrimp together comes down to careful planning and creating an environment that prioritizes the well-being of both species. If you’re unsure, it’s always best to err on the side of caution and choose fish that are known to be more shrimp-friendly.

What Makes The Molly Fish Eat Shrimp?

While mollies are primarily omnivorous, they do tend to munch on Shrimp, and several factors play into this behavior:

1. Opportunistic Eating: As general scavengers, mollies will readily consume whatever edible morsels they come across. If Shrimp are readily available and accessible, they may be seen as a tasty snack. This is especially true for smaller Shrimp or vulnerable juveniles.

2. Protein Need: While algae and plant matter form a large part of their diet, mollies require protein for growth and health. Shrimp offer a concentrated source of animal protein, making them an attractive food source, especially for breeding females or growing youngsters.

3. Competition and Boredom: In crowded tanks with limited food, mollies may become more aggressive and opportunistic, leading them to prey on slower-moving Shrimp. Additionally, a lack of enrichment and stimulation can make Shrimp seem more interesting as a potential target.

4. Individuality: Like other fish, individual mollies can have varying personalities and hunting instincts. Some mollies may be naturally more predatory than others, leading to a higher likelihood of shrimp predation.

However, it’s important to note that factors like tank size, plant cover, and shrimp species also play a role in the dynamic between mollies and Shrimp.

Here are some tips to minimize the risk of mollies eating Shrimp:

  • Provide ample hiding places: Densely planted tanks with rocks, driftwood, and other structures offer shelter for Shrimp to avoid predatory fish.
  • Choose larger shrimp species: Some shrimp, like Amano shrimp, are too large for most mollies to prey on effectively.
  • Maintain good water quality: Stressful environments can make Shrimp more vulnerable and encourage scavenging behavior in mollies.
  • Offer alternative high-protein foods: Regularly feeding brine shrimp, bloodworms, or other protein-rich foods can satiate mollies and reduce their interest in Shrimp.

By taking these steps, you can create a harmonious environment where both mollies and Shrimp can thrive together.

Remember, observing your molly’s behavior and tailoring your tank accordingly will help you understand their individual needs and ensure a balanced and healthy ecosystem for all your aquarium inhabitants.
