Goldfish are generally peaceful fish that do not consume other species or their eggs; however, this can happen occasionally during mating season or following significant water changes.
Fish are known to consume snails and shrimp. Some aquarium owners even incorporate earthworms into the tank for added nutrition.

They are opportunistic eaters
Goldfish are opportunistic feeders and enjoy searching for their food throughout the day. In nature, goldfish feast on insects, plant matter, crustaceans and even other fish! Their small mouths make it hard for them to consume large quantities at once but they will keep looking until something suitable comes their way!
Goldfish do not possess teeth in their jaws; instead, they possess pharyngeal canines – small hard plates located at the back of their throats that help grind and chew food before swallowing it. Goldfish also make excellent sifters; often eating gravel along with their pellets or flake to complete digestion.
Feed your goldfish correctly! An excess of food can overload their digestive tracts and lead to illness. Also be sure to provide balanced meals three times daily with quick cleanup times of two minutes for whatever they don’t consume.
They are not aggressive
Goldfish are generally peaceful fish that coexist well with other types. While they will opportunistically feed on other fish species, they usually don’t attack other types except in rare circumstances.
If your goldfish is being aggressive towards its tank mates, it’s essential that you understand why this behavior has occurred. It could be an indicator that they are sick, or perhaps just competing for food resources – to avoid this happening again in future, feed your goldfish regularly throughout the day.
Goldfish often graze at the bottom of their aquatic environments and will consume anything edible, from store-bought fish flakes and algae flakes to detritus, fecal matter and lost scales. When in nature they feed opportunistically on aquatic vegetation, frogs, newts and eggs; their long trailing fins may even become targets for other fish and can result in injuries, excess slime build-up or fin damage to other individuals.
They are not predatory
Goldfish are omnivores, meaning they consume nearly anything that fits in their mouths. When kept in community tanks, goldfish typically feed on pellet and flake food pellets but may also munch on fresh vegetables and other fish foods. Their long and torpedo-shaped bodies allow their digestive systems to accommodate different food sources efficiently.
Goldfish in the wild eat aquatic plants, snails, insects, fish eggs and other small animals that reside within bodies of water they invade. Their feeding habits also can damage an ecosystem as their foraging behavior uproots and mixes up sediment which interferes with natural ecosystem functions and causes increased algae blooms.
If you bring home a goldfish, make sure its tank is well stocked with similar-sized fish; otherwise it may attack or consume them. Goldfish also need plenty of room and may display aggressive behavior if feeling restricted; consider getting a tank divider if this occurs.
They are not cannibals
Goldfish are not cannibals and will never consume other fish; however, in certain environments (lack of space or overfeeding), they may consume their own babies as a form of self-defence. This may lead to their death; thus it is essential that you feed them a balanced diet while providing them with sufficient space.
Goldfish in their natural environment eat insects, crustaceans, plants and small animals such as insects. Being opportunistic eaters, goldfish will eat whatever is available to them – including smaller goldfish if their mouths can accommodate it.
Goldfish that have become hungry may become aggressive and begin nibbling at each other’s fins, possibly as a sign that one fish is sick or dead and poses a threat, or fighting over food or territory. Such behavior could also result from changes to tank conditions such as a temperature spike or lower oxygen levels, leading to their behavior changing suddenly and unpredictable.
