Preparing the Tank for Angelfish and Goldfish

Aquarium Temperature

The goldfish are cold-water fish, and the angelfish are tropical fish, as mentioned above. The goldfish do grow at 16.6°C to 22.2°C, and the angelfish at 23°C.

If their favorable temperature is not maintained, the fish may stop eating, get sick, become aggressive, and die.

Due to this reason, these species should be kept separate and allowed to live in their favorable climates.

Aquarium Size

These two species may trigger if you keep them in the small tank. This can lead to a stop in their growth and affect their health conditions.

Angelfish need 4 gallons of water per fish, whereas goldfish need 10 gallons of water per fish. To avoid overcrowding, you should keep angelfish and goldfish in separate tanks.

Tank Size and Shape Requirements

The size and shape of the tank are critical factors to consider when keeping Angelfish and Goldfish together. Angelfish require tall tanks with a minimum height of 18 inches to accommodate their body shape and long fins. On the other hand, Goldfish require large tanks with a minimum size of 20 gallons per fish. It is recommended to choose a tank size of at least 55 gallons to accommodate both species adequately. Moreover, the tank should have ample swimming space, hiding spots, and vegetation to provide a suitable environment for both species.

Water Quality and Temperature

The water quality and temperature are also crucial considerations when keeping Angelfish and Goldfish together. Both species have different water requirements, and it is important to create a balanced environment for both. Goldfish thrive in cold water with a temperature range of 65-75°F, while Angelfish prefer warmer water with a temperature range of 75-82°F. Additionally, the pH level should be between 6.5 and 7.5, and the water hardness should be between 5-12 dGH.

Aquarium pH Level

Sadly, both species prefer different pH levels. The favorable pH for goldfish is 7.2 to 7.6. Meanwhile, for angelfish, it is 6.8.

Can Angelfish kill Goldfish?

Angelfish are generally peaceful, but they do get aggressive sometimes due to a few reasons. However, it’s totally beyond belief that your angelfish will kill a goldfish.

If the goldfish present in the tank is smaller than the angelfish, that means they can eat the goldfish, so it’s better to separate the goldfish.

Choosing the Right Tank Mates

Choosing the right tank mates is crucial when keeping Angelfish and Goldfish together. Both species are peaceful and can coexist with other peaceful fish. However, Angelfish can be aggressive towards smaller fish, while Goldfish tend to nip at other fish’s fins. It is recommended to choose tank mates that have similar water requirements and are peaceful, such as Guppies, Tetras, or Corydoras.

Introducing Angelfish and Goldfish to the Tank

Let’s understand what things we have to consider while introducing both each other

Quarantine Process for New Fish

Before introducing new fish to the tank, it is essential to quarantine them for a minimum of 2-3 weeks. Quarantine helps prevent the spread of diseases and parasites to the existing fish in the tank. It is recommended to keep the new fish in a separate tank with similar water conditions, proper filtration, and heating. During quarantine, the new fish should be monitored for any signs of illness or disease.

Acclimating Angelfish and Goldfish

Acclimating new fish to the tank is crucial to prevent stress and shock, which can lead to illness and death. To acclimate the new fish, place them in a bag with water from their quarantine tank and float the bag in the tank for 15-20 minutes. This will help the fish adjust to the temperature and water conditions in the tank. Afterward, release the fish slowly into the tank.

Monitoring Fish Behavior and Health

After introducing new fish to the tank, it is essential to monitor their behavior and health closely. Angelfish and Goldfish are peaceful fish, and any signs of aggression or stress should be addressed immediately. Common signs of stress include hiding, loss of appetite, and unusual behavior. Additionally, regular water testing and tank maintenance are crucial to maintaining a healthy and happy environment for the fish.


While it is possible to keep Angelfish and Goldfish together, it requires careful planning and preparation. Before deciding to mix these two species, it’s important to consider their individual characteristics and habitat requirements, as well as the potential issues that may arise. With the right tank setup, water quality, and monitoring, it is possible to create a healthy and happy community tank with both Angelfish and Goldfish.

Additionally, other cichlids may pose a threat to Angelfish, as they may compete for territory or resources. It’s important to research and choose tank mates that have similar size, temperament, and habitat requirements.

Do angelfish bite goldfish?

If the tank is properly prepared and the fish are provided with adequate space and hiding spots, they should be able to coexist peacefully. However, it’s important to monitor the fish closely and separate them if any aggression or territorial behavior is observed.
