Can Goldfish Live With Angelfish? (No, Is It Risky…)

Goldfish and angelfish are both popular choices for aquariums, but do these two species of fish make good tankmates? Can goldfish live with angelfish in the same tank or is it a recipe for disaster? Below is your answer.

No, goldfish and angelfish should not be kept in the same tank. Goldfish are coldwater fish while angelfish are warm-water fish, so they have different temperature needs. Additionally, goldfish produce a lot of waste which can harm angelfish like cleaner water.

Furthermore, goldfish tend to be aggressive and may bully or even try to consume smaller angelfish.

In summary, it is best not to put goldfish and angelfish together in the same tank as they have different care requirements and may cause each other harm.

In this blog post, I’ll cover the reasons why goldfish and angelfish should not be kept together, explain how to keep them in separate tanks and suggest some other species of fish that can live comfortably with each type of fish. Keep reading to learn more!

Why Can’t Goldfish and Angelfish Live Together?

Can Goldfish Live With Angelfish

Goldfish and angelfish belong to two completely different families. Goldfish are members of the Cyprinidae family, while angelfish belong to the Cichlidae family.

These two types of fish have different habitats and dietary needs, which makes it difficult for them to co-exist peacefully in one tank. Furthermore, goldfish and angelfish have very different personalities, which can lead to aggressive behavior.

Goldfish typically prefer colder water with a pH balance of 6.5-7.0, while angelfish prefer warmer water with a pH balance of 7.2-8.4. Goldfish are also more adaptable than their cichlid cousins and they can survive in both fresh and saltwater.

On the other hand, angelfish are only native to freshwater habitats. This discrepancy in habitat preferences prevents goldfish and angelfish from living together peacefully.

Furthermore, goldfish have much higher oxygen requirements than angelfish. Goldfish need at least 6-7mg/L of dissolved oxygen in their water, while angelfish can do just fine with 2-4mg/L.

This is likely due to the fact that goldfish are a much more active species than their cichlid counterparts. So, if placed in the same tank, the goldfish would quickly deplete all the available oxygen, leaving the angelfish gasping for air.

Lastly, goldfish and angelfish have very different personalities. Goldfish are typically more docile and shy, while angelfish tend to be quite territorial and aggressive.

This behavior can lead to unnecessary stress in both fish, as well as possible injury or death if they do not get along.

How Do I Set Up a Goldfish and Angelfish Tank?

How Do I Set Up a Goldfish and Angelfish Tank?

Setting up a goldfish and angelfish tank can be an exciting adventure, but it’s important to follow the right steps in order to ensure a healthy environment for your fish. The following are some tips on setting up a goldfish and angelfish tank:

1. Location

The location of your tank is very important. You should choose a spot that is away from direct sunlight and exposed to as little natural light as possible.

Make sure the area is not too hot or cold, and if it’s in a busy part of your house, make sure to provide enough soundproofing materials (like blankets) to reduce noise levels.

2. Tank Size

The size of your tank will depend on how many fish you plan to keep. Goldfish and angelfish need plenty of space to swim, so it’s important to choose a tank that is large enough for them.

A 30-gallon tank should be adequate for one or two goldfish and an angelfish.

3. Decorations

You should include decorations in your tank to make it more appealing to the fish. Rocks, driftwood, and artificial plants can create a natural-looking environment for them.

Avoid using too many ornaments that could potentially harm the fish.

4. Filtration

It’s important to have a good filter to keep the water clean and free of toxins. Choose a filter that is appropriate for the size of your tank and make sure to clean it regularly.

A biological filter is also a great choice, as it helps break down waste material from fish into nitrate (a harmless form of nitrogen).

5. Water

It’s important to use a water conditioner when setting up your tank. This will remove chlorine, chloramine, and other impurities from the tap water that could harm your fish.

You should also test the pH levels of the water on a regular basis to make sure they are within an acceptable range (between 6.5-7.5).

These are just some basic tips for setting up a goldfish and angelfish tank. With the right setup, you can create a happy and healthy home for your fish.

What Are the Best Tank Mates for Goldfish?

What Are the Best Tank Mates for Goldfish?

When considering adding additional fish to the tank, it’s important to choose species that are compatible with the temperament and water requirements of goldfish.

Since they require cold water, most tropical fish (which prefer warmer temperatures) are not suitable tankmates. It’s also wise to avoid fish with long fins, as goldfish may nip at them.

So what are the best tank mates for goldfish? Here is a look at some of the top options:

1. White Cloud Mountain Minnows

White cloud mountain minnows are small species of freshwater fish native to China and Taiwan.

They can tolerate relatively cool water temperatures, making them the perfect companion for goldfish.

Not only do they look great in an aquarium, but they are also quite active and fun to watch.

2. Guppies

Guppies are another popular small fish species that can be kept together with goldfish.

They have bright colors and long fins which may make them susceptible to nipping, but they are a hardy and adaptable species that can tolerate the cool water temperatures favored by goldfish.

3. Cherry Barbs

Cherry barbs are an ideal tank mate for goldfish because they possess many of the same traits as guppies.

They have bright red-orange coloration and enjoy swimming in schools. They also have robust and adaptable personalities, making them a great choice for goldfish tanks.

4. Otocinclus Catfish

Otocinclus catfish are small bottom-dwelling fish that are an excellent addition to the goldfish tank.

They have interesting behaviors such as “sucking” algae from rocks and glass. They are also peaceful, so they won’t bother the goldfish or compete for food.

5. Weather Loaches

Weather loaches (also known as dojo loaches) are big enough to co-exist with goldfish without worrying about nipping or aggression.

They enjoy digging in the substrate which makes them interesting to watch, and they also help keep the tank clean by eating excess fish food.

Overall, there are many different types of fish that can make great tank mates for goldfish.

When choosing companions for your goldfish, it’s important to remember to select species that are compatible with the temperature requirements, temperament, and size of your goldfish.

With careful selection, you can create a peaceful and beautiful aquarium that is sure to bring you many years of enjoyment.

What Are the Best Tank Mates for Angelfish?

When selecting tank mates for angelfish, it’s important to choose species that are compatible with the temperaments and water requirements of your angelfish.

Angelfish prefer warm or tropical waters, so most cold-water fish (such as goldfish) are not suitable companions.

It’s also important to select fish with similar size and temperament since angelfish can become territorial and may nip at their tank mates.

Finally, it’s a good idea to pick species that have different behaviors so that your aquarium is more interesting to watch.

1. Peaceful Community Fish

Fortunately, there are many freshwater species that make suitable tank mates for angelfish.

Peaceful community fish such as tetras, barbs, and rasboras are peaceful enough to co-exist with angelfish without fear of aggression or nipping.

These small schooling fish can also help to keep your angelfish entertained and can add a lot of color to the tank.

2. Other Popular Tank Mates

In addition to peaceful community fish, there are several other species that make great tank mates for angelfish.

Dwarf cichlids, such as Apistogramma and Kribensis, are small enough to co-exist with angelfish and are known to help keep the tank clean.

Otocinclus catfish and plecos are also excellent choices as they will happily graze on algae from the glass and rocks in your aquarium. They can help to reduce maintenance time while adding interest to your aquascape.

Finally, if you have a large enough tank, angelfish can safely co-exist with other semi-aggressive species such as Discus and Gourami.

How Often Do I Need to Feed Goldfish and Angelfish?

Goldfish and angelfish should be fed at least once a day, but no more than twice a day. It’s important to give them the right amount of food for their size, as overfeeding can lead to water quality issues and unhealthy fish.

If your goldfish or angelfish are not eating all of the food in one sitting, reduce the amount you are feeding them.

Frozen and live foods can also be given occasionally, but should not be used as their main source of nutrition.

Overall, it’s important to provide your goldfish and angelfish with a balanced diet to ensure they stay healthy and happy.

What Are Some Common Problems With Keeping Goldfish and Angelfish Together?

Keeping goldfish and angelfish together can be a rewarding experience, as they are both colorful and peaceful species that make an attractive addition to any aquarium.

However, it is important to understand the potential issues associated with keeping these two species in the same tank before attempting to do so.

In this part, I’ll explore some of the common problems that arise when keeping goldfish and angelfish together, as well as how to overcome these issues.

1. Habitat Compatibility

Goldfish require more space and a higher oxygen content than angelfish, meaning that setting up an aquarium that is suitable for both species can be challenging.

Goldfish will require more expansive tanks with plenty of open swimming space, while angelfish prefer narrow tanks with lots of vegetation and decorations.

Inadequate tank size can mean that the goldfish become stressed out or even injury due to a lack of swimming room, while overcrowding can cause the angelfish to suffer from poor water quality.

2. Feeding Habits

Goldfish are known to be more voracious eaters than angelfish and can quickly outcompete their tankmates for food.

This can cause the angelfish to become malnourished, resulting in stunted growth and even death.

To ensure that both species are getting an adequate supply of food, it is important to separate them during feeding and provide different types of food.

3. Water Quality

Goldfish produce more waste than angelfish, meaning that their tanks must be regularly monitored and maintained to ensure the water remains clean and suitable for both species.

Without adequate filtration and frequent water changes, the tank can quickly become overrun with toxins such as ammonia, nitrite, and nitrate, which can be harmful to both species.

4. Socialization

Goldfish are much more active and social than angelfish, meaning that they are likely to outcompete their tankmates for territory and resources.

This can cause the angelfish to become stressed or even bullied, resulting in poor health or even death.

To ensure that both species can peacefully coexist, it is important to provide plenty of hiding spots and decorations for the angelfish to retreat to.
