Why Can’t Angelfish And Goldfish Live Together?

Angelfish and goldfish can’t live with each other for a number of reasons. First of all they have different temperature requirements. And if that isn’t enough, angelfish can be quite aggressive, and may end up attacking your goldfish if you put them in the same tank (depending on their size.

(Don’t worry just yet, here are some alternative tank mates for your goldfish!)

Angelfish And Goldfish Temperature Differences

When it comes to keeping fish, water temperature is a critical factor to consider. Goldfish and Angelfish are two popular species that have different temperature requirements, which makes them incompatible tank mates.

Goldfish Temperature

Goldfish prefer a water temperature between 62-74°F (20-23°C) and can tolerate fluctuations in temperature. However, sudden changes in temperature can cause stress and illness in goldfish.

Angelfish Temperature

On the other hand, Angelfish prefer a warmer water temperature between 78-84°F (25-29°C), making them more suited to tropical aquariums. They are sensitive to changes in temperature and can experience stress and illness if the water is too cold.

Because of these differences in temperature requirements, it’s not recommended to house Goldfish and Angelfish together in the same tank.

Mixing these species could lead to stress, illness, and even death for one or both of the fish. It’s important to research the temperature requirements of any fish species before adding them to your aquarium and to choose compatible tank mates to ensure the health and happiness of each fish.

Differences In pH Needs Between Angelfish And Goldfish

Goldfish

Water pH levels are also important to consider when choosing tank mates for your goldfish. Goldfish prefer a pH level between 6.5 – 7.5, which is slightly alkaline. They can tolerate a wide range of pH levels, but sudden fluctuations can cause stress and illness.

Angelfish

Water pH levels are an important factor to consider when selecting tank mates for your angelfish. Angelfish prefer a pH level between 6.5-7.1, which is slightly acidic to neutral.

They are sensitive to changes in pH levels and can experience stress and illness if the water becomes too alkaline. It is important to maintain a consistent pH level in the tank to ensure the health and well-being of your angelfish.

Feeding Habits In Angelfish And Goldfish

Feeding habits are an important factor to consider when keeping fish in an aquarium. Different species have different dietary requirements, and it’s important to provide them with the appropriate foods to ensure their health and wellbeing.

Goldfish:

Goldfish are omnivores and have a hearty appetite, making them relatively easy to feed in captivity. They can eat a variety of foods, including flakes, pellets, and vegetables, and should be fed small amounts of food multiple times a day to prevent overeating.

Angelfish:

Angelfish are primarily carnivores in the wild, but in captivity, they have adapted to being fed a mix of plant and animal-based foods, making them omnivores.

They prefer a diet of live or frozen foods, such as brine shrimp or bloodworms, but can also be fed flakes and pellets. Angelfish have a more selective appetite and may refuse to eat certain foods, so it’s important to offer a variety of options to ensure they receive proper nutrition.

Size And Aggression

One of the most important things to consider when keeping fish together is there individual sizes and aggression. This is where issues between goldfish and angelfish truly begin.

Goldfish Size & Aggression

When it comes to size and aggression, goldfish are generally peaceful creatures that can live with other fish of similar size and temperament. In fact, goldfish can grow extremely large in the right conditions, reaching up to 16 inches in length

However, they can become territorial and aggressive towards smaller fish, so it’s important to monitor their behavior and make sure they are not harassing or harming other fish in the tank.

Angelfish Size & Aggression

Angelfish, on the other hand, are known to be aggressive and territorial. They can become aggressive towards other fish, especially those of similar size or shape.

In general you can expect your angelfish to grow between 4-8 inches in length

It’s important to keep them in a larger tank with plenty of hiding spots to prevent territorial disputes. Additionally, introducing angelfish to a tank with other established fish can be difficult, as they may view the other fish as a threat to their territory.

Overall, it’s important to consider the size and aggression of both goldfish and angelfish when choosing tank mates. Ensuring that fish are of similar size and temperament can help prevent aggression and territorial behavior, and providing ample hiding spots can give fish a space to retreat and feel safe.
