Can Goldfish Live with Amano Shrimp?

Goldfish are beautiful and popular aquatic pets that are often kept in home aquariums.

They come in a variety of colors, sizes, and shapes, making them an attractive addition to any fish tank.

On the other hand, Amano shrimp are fascinating freshwater invertebrates known for their ability to keep aquariums clean by consuming algae and waste materials.

Many aquarium enthusiasts wonder if goldfish and Amano shrimp coexist peacefully in the same tank. So, let’s find out about the compatibility of goldfish and Amano shrimp.

The Nature of Goldfish

Goldfish are generally peaceful and sociable creatures. They prefer to live in groups and thrive in spacious environments with plenty of swimming space. However, it is important to note that goldfish are omnivores, which means they have a diet that includes both plant and animal matter. Additionally, goldfish produce a significant amount of waste, which can lead to poor water quality if not properly managed.

Amano Shrimp: The Efficient Cleaners

Amano shrimp, also known as Caridina multidentata, are small invertebrates native to Japan. They have gained popularity in the aquarium hobby due to their excellent cleaning abilities. Amano shrimp are voracious algae eaters and scavengers, diligently browsing aquarium surfaces for any leftover food, debris, and algae. They can help maintain a healthy ecosystem in your tank by keeping it clean and reducing the accumulation of unwanted substances.

Compatibility Factors

While goldfish and Amano shrimp may seem like an interesting combination, there are several factors to consider before introducing them to the same tank. Here are some key points to keep in mind:

Tank Size and Water Parameters

Goldfish are known to grow quite large, and they are active swimmers. Therefore, they require a spacious tank with ample swimming space. On the other hand, Amano shrimp are relatively small and can thrive in smaller aquariums. The tank size should be suitable for both species, ensuring that the goldfish do not crowd or stress the shrimp. Additionally, it is crucial to maintain appropriate water parameters such as temperature, pH, and ammonia levels to support the well-being of both goldfish and Amano shrimp.

Feeding Habits and Competition

Goldfish have a hearty appetite and tend to consume both plant matter and small animals. While they primarily rely on commercial fish food, they may also nibble on live or frozen foods like brine shrimp, daphnia, and bloodworms. Conversely, Amano shrimp are primarily herbivores, relying on algae and organic debris. It is crucial to consider the dietary requirements of both species and ensure that each is adequately fed to prevent competition for food.

Goldfish Aggression

Although goldfish are generally peaceful, some varieties, such as the fancy goldfish, have long, flowing fins that can be tempting for them to nibble on. In such cases, they may mistake Amano shrimp’s long sensory antennae or other appendages as food and accidentally harm them. Carefully observe the behavior of your goldfish when introducing them to Amano shrimp, as any signs of aggression should be taken seriously to prevent injury or stress to the shrimp.

Breeding and Reproduction

Both goldfish and Amano shrimp have unique reproductive behaviors. Goldfish are known to breed prolifically, producing large numbers of fry (baby fish) that require special care and attention. On the other hand, Amano shrimp can reproduce in freshwater aquariums, but their larvae require brackish water conditions to survive. If you have a community tank with goldfish and Amano shrimp, you may find it challenging to provide the ideal conditions for both species’ reproduction.


In conclusion, while it is possible to keep goldfish and Amano shrimp together in the same tank, several considerations need to be taken into account. Tank size, water parameters, feeding habits, goldfish aggression, and reproductive behaviors are crucial factors to ensure the compatibility and well-being of both species. It is essential to closely monitor their interactions and provide suitable conditions for each species to thrive. By carefully planning and implementing the necessary measures, you can create a harmonious and balanced aquatic ecosystem with goldfish and Amano shrimp in your aquarium.
n commercial fish food, they may also eat live or frozen foods. Amano shrimp, on the other hand, are primarily herbivorous and feed on algae and detritus. There may be competition for food between goldfish and Amano shrimp, especially if the tank does not have enough algae or if the goldfish consume all the food before the shrimp have a chance to eat. Providing ample food and ensuring that both species have access to their preferred diet is essential for their coexistence.

Aggression and Predation

Goldfish are generally peaceful, but they have a tendency to nibble on small objects and organisms. While Amano shrimp are not typically targeted as prey by goldfish, there is a possibility that the shrimp’s antennae or limbs may be mistaken for food. Additionally, goldfish may accidentally injure or stress the shrimp while swimming or moving decorations. It is important to monitor their interactions closely and provide hiding places or vegetation to give the shrimp a safe retreat.

Waste Management

As mentioned earlier, goldfish produce a significant amount of waste, which can lead to poor water quality if not managed properly. Amano shrimp help in keeping the tank clean by consuming algae and waste materials. However, if the goldfish produce excessive waste, it may overwhelm the shrimp’s cleaning abilities. Regular water changes and proper filtration are crucial to maintain optimal water conditions for both goldfish and Amano shrimp.


In conclusion, the compatibility of goldfish and Amano shrimp depends on several factors such as tank size, water parameters, feeding habits, aggression, and waste management. While it is possible for them to coexist peacefully in the same tank, careful consideration and proper care are necessary to ensure the well-being of both species. Monitoring their interactions, providing appropriate food and hiding places, and maintaining good water quality are essential for a successful combination.
