The answer to the question: Why is my goldfish eating my other fish? Some of the ways, an owner can prevent goldfishes from killing other fishes are as follows
Provide Enough Space
A goldfish will naturally become aggressive when they don’t have enough space to roam freely. A tight space will make them agitated and stressed, which will affect their health. An owner should provide at least 10 gallons of water for each of their goldfish. If the owner has 4 goldfish, they will need 40 gallons of water.
An overcrowded tank will encourage goldfish to take the lives of other fishes and make room for themselves.
Furthermore, because goldfishes produce a lot of waste during the day, overcrowded tanks might not be as hygienic as required, which will make the tank a poor place for goldfishes. So, owners are recommended to provide large enough space, for goldfishes to be more friendly towards each other.
Water is also important for fish. Space and water are somehow correlated to each other. If the fish is kept in little space, water will naturally turn unhygienic and poor more quickly. Poor water quality can be another stressful situation for goldfishes to bite other fishes.
To keep the water clean, owners should have fish limited to the quantity of water and clean the water at least once or twice a week as required.
Food given to the goldfish should be of high quality and it should be provided at a specific time and that too in a specific quantity. The digestion process of goldfish is a lot different from any other animal. They don’t have a stomach, so the food doesn’t stay inside them for too long.

When feeding, the owner should keep in mind to not overfeed them or never underfeed them. Overfeeding will cause health problems and underfeeding will make them eat each other.
Sometimes, an owner may misunderstand their goldfish to be eating other fish while in reality, they may be trying to mate with other goldfish. When a male goldfish is chasing down a female goldfish, it often looks more like an aggressive move to humans while it’s not.
However, an owner should always keep in mind to separate the pregnant fish from others and baby fishes should also be separated when mothers have given birth to them. As excessive babies often are eaten by adult guppies to make some space.
An additional effort can make a lot of difference. The owner should take extra measures to make sure that the fishes aren’t trying to kill each other. Some extra measures like adding a separator would help in keeping fish in the same tank and at the same time, the risk of them eating one another is reduced.
Additionally, to improve the quality of water and to keep the water clean for a long time, owners can add live plants which will give a more natural touch and keep the water clean for a long time.
Adding other natural elements like rocks or artificial structures will also help them to have a hiding spot from one another.
