Do Ghost Carp Eat Other Carp? Or they Prey on Other Fish?



Do Ghost Carp Eat Other Carp

Have you heard of ghost carp? These unique fish, a variant of common and mirror carp, have a pale, translucent appearance due to a genetic mutation. Ghost carp populations, especially in the UK, have been increasing. While some appreciate their beauty in ponds and lakes, others see them as invasive and potentially hybridizing with wild carp.

Understanding ghost carp’s characteristics, behaviour, and impact on other carp species and ecosystems is crucial. In this article, we’ll delve into this carp species, and answer the questions about do ghost carp eat other carp, or even other fish species.

Do Ghost Carp Eat Other Carp?

Ghost carp primarily feed on a diet of plants, insects, and small aquatic creatures. However, there have been reports of ghost carp exhibiting opportunistic behaviour and consuming the eggs of other carp species. While it’s not their main source of food, if given the chance, ghost carp may consume the eggs of other carp.

This behaviour could potentially impact the populations of other carp species in certain environments. So it is important to study and understand these interactions to maintain the balance of aquatic ecosystems and protect the diversity of fish species.

Origins of Ghost Carp: Where They Come From?

Ghost carp, a captivating variety of koi, have gained popularity worldwide, including in the United States and the UK. Originating in Japan as ornamental fish, they were first introduced to North America in the 1960s and have since spread across the globe.

However, their presence raises concerns about their impact on native ecosystems. Ghost carp’s rapid reproduction and competition for resources can disrupt the natural balance, potentially causing a decline in biodiversity by outcompeting native species.

Distinct Characteristics of Ghost Carp: Feeding Habits, Social Structure, and Reproduction

While ghost carp may look similar to other types of carp species, there are several distinct characteristics that set them apart. One of these is their white or silver scales, which gives the fish a ghostly appearance (hence their name). Ghost carp also tend to grow larger than other types of koi and have a more peaceful temperament.

What Do Ghost Carp Eat?

Ghost carp are a omnivorous fish species and feed on a variety of food sources such as insects, crustaceans, fish eggs, small fish, and guppies. They also consume plant matter like algae and aquatic plants. Due to their varied diet, ghost carp can be caught using a wide range of fishing baits including worms, maggots, cat food, sweetcorn’s, boilies, and bread.

Social Structure

Like other fish species in the Cyprinidae family such as common carp and mirror carp, ghost carp have a social structure that involves schooling behaviour. Ghost carp tend to swim together in groups for safety reasons and they also exhibit territorial behaviour where they defend their space against other fish species such as catfish or other types of carps.


Ghost carp reproduce through spawning where female fish lay eggs and males fertilize them. The breeding season usually occurs during spring when water temperatures rise above 15°C (59°F). During this time, male ghost carps develop breeding tubercles on their head which helps them grip onto the female during spawning.

Once fertilized by the male’s milt (sperm), the eggs hatch within 3-7 days depending on water temperature. The larvae emerge from the gravel substrate after hatching and start swimming actively towards light sources which indicates surface waters where they can find food.

Do Ghost Carp Eat Other Fish?

Ghost Carp fish have an omnivorous diet. This means that they eat both plants and animals. Their diet can vary depending on their habitat and availability of food sources. In the wild, ghost carp fish feed on aquatic plants, insects, crustaceans, and even on small fish. In captivity, they are fed pellets or flakes specially formulated for their nutritional needs.

While ghost carps may eat other smaller fish, there is no evidence that they specifically target larger fish species. They are not known to be aggressive towards other fish and usually coexist peacefully with other pond or aquarium inhabitants.

Best Food for Ghost Koi Carp

Ghost koi fish are a popular addition to any koi pond due to their unique, translucent appearance. These fish require a balanced diet to maintain good health and vitality.

Feeding your ghost koi a high-quality fish food specifically formulated for koi and goldfish is recommended. These types of foods provide the necessary nutrients that ghost koi need to thrive. Look for foods that contain a mix of both protein and vegetables.

It’s important to note that true koi carp have different dietary needs than ghost koi. While they may look similar, they are two distinct species with different nutritional requirements. Therefore, it’s crucial to choose the right food for your specific fish.

What Do Ghost Koi Eat?

Ghost koi eat both plants and animals in the wild, so it’s essential that their diet reflects this balance in captivity. A quality pellet or flake food should make up most of their diet. But you can also supplement their meals with live or frozen foods such as brine shrimp or bloodworms.

Vegetables like peas, lettuce leaves, and spinach can also be offered occasionally. These veggies provide fibre and other essential nutrients that help keep your ghost koi healthy.

How Best to Look After a Ghost Koi?

Aside from feeding them properly, there are several things you can do to ensure your ghost koi stays healthy:

  • Keep their water clean: Regularly test the water quality in your pond and perform water changes when necessary.
  • Provide adequate space: Make sure your pond is large enough to accommodate all of your fish comfortably.
  • Monitor temperature: Ghost koi prefer cooler water temperatures between 65-75°F (18-24°C).
  • Avoid overfeeding: Overfeeding can lead to health problems and poor water quality.

The Importance of Feeding Ghost Carp Well

Ghost carp require proper care and attention. One of the most important aspects of caring for ghost carp is feeding them well. Providing a balanced diet of pellets, vegetables, and live food is the best way to ensure their health and growth.

As omnivores, ghost carp will eat anything from small fish and fish eggs. However, it is also important to make sure they receive a varied diet that meets all their nutritional needs. Many years of experience have shown that feeding ghost carp a varied diet is the best means of ensuring their health and vitality.

Tips for Reducing the Number of Ghost Carp

Ghost carp can be found in many bodies of water, including ponds, lakes, and rivers. While they are not harmful to humans or other aquatic life, they can become invasive if their populations grow too large. Here are some tips for reducing the number of ghost carp:

  • Harvesting: Anglers can use ghost carp as bait but should only do so after making sure they are well-fed and healthy.
  • Sterilization: Some states allow sterilization programs for invasive species like ghost carp. This process involves removing the fish’s reproductive organs to prevent them from reproducing.
  • Limiting Introductions: Avoid introducing new ghost carp into ponds or lakes where they don’t already exist.

How Long Can They Go Without Food?

Ghost carp can go without food for several days without any adverse effects on their health. However, it’s essential to maintain a regular feeding schedule to ensure their continued growth and ensure they stay in good health.


After studying the behaviour and diet of ghost carp, it’s clear that they don’t consume other carp. Although they may eat smaller fish and insects, their primary diet consists of vegetation. Ensuring ghost carp receive a balanced diet is essential for their well-being.

To properly feed ghost carp, offer them a variety of foods like algae wafers, vegetables, and herbivorous fish pellets. By providing nutritious meals, you can support their growth and longevity. If you want to learn more about, do carp eat other fish, read these pages.
