How Long Can Angelfish Go Without Food

Can Angelfish go without food for a long time? If they get enough oxygen, they can last up to two weeks without eating. Aside from humans, this is one of the longest fasting times known among vertebrates.

 How Long Can Angelfish Go Without Food?

The answer to this question is not as straightforward as one might think. There are many factors that come into play when determining how long a fish can go without food. Some of these include the size of the tank, the size of the fish and its metabolism. Regardless, there are some general guidelines that can help you know how long your fish can go without food before it becomes an issue.

How Long Can Angelfish Go Without Food?

If you have a small aquarium with only a few fish in it, they should be able to survive for several days without food if necessary. If your aquarium is larger or you have more than one type of fish in it, you may need to feed them more often depending on their individual needs. If you have an angelfish with a large tank and many other types of fish, then it is best to feed them at least once per day even if they don’t seem hungry, so they don’t starve themselves out of boredom or frustration.

 Reasons Why Your Angelfish Is Not Eating

  • If your angelfish is not eating, there could be several reasons for this.

The first thing to consider is the stress level of your fish. If you’ve recently added new fish or rearranged the tank, it’s important to allow time for your angelfish to adjust. If fish have been fighting and have lost scales or torn fins, they may not feel comfortable enough in their environment to eat.

If you have a single angelfish, try adding another fish to keep them company. If you have multiple angelfishes and they’re still not eating, consider rearranging the tank so that all of them are closer together; some species of angelfish prefer to live in groups as large as twenty.

Another reason why your angelfish may not be eating is because of improper water quality or water temperature. Angelfish are extremely sensitive to water conditions and can become sick if they aren’t kept in clean water with the right temperature range (20-25 degrees Celsius). You should test your water weekly using an aquarium kit and perform partial water changes when necessary.

 CanAnglers Be Kept Together in The Same Tank?

Angelfish are a very popular species of tropical fish, but they can be a challenge to keep. They require soft, acidic water and they should not be kept with other angelfish or with other types of fish that may nip at their long fins. It is also important to know how long angelfish can go without food. If you are thinking about keeping an angelfish in your aquarium, it is important that you learn about their needs before you make the decision.

Angels are social animals and will do better in a group of at least three. If you plan to keep only one angelfish, then it will do best if it has a companion of another species like a clownfish or goby because these fish will help protect the angelfish from predators. When it comes to keeping different types of fish together, it is always best to research which species are compatible before adding any new fish to your tank.

 How Long Can Fish Go Without Eating?

  • In general, fish can go without eating for up to 24 hours. However, this does depend on a number of factors. Here are some things to consider:
  • If you have an aquarium with many fish in it, then it is best if you feed them at least once a day. Otherwise, they may eat each other’s food and cause harm to the other fish in your tank.
  • If the fish has been sick or injured, then you should not feed them until they are better. This is because they need to heal before they can eat again.
  • You should also not feed your fish if they do not seem hungry or interested in food. If they do not want it, then it is best not to force them into eating something when they are not interested or hungry.

How to Get Your Angelfish to Eat

Angelfish are omnivorous and will eat a wide variety of foods if they are given a choice. However, because of their large size and relatively slow metabolism, it is important not to overfeed them.

  • In the wild, angelfish will usually feed on smaller fish, crustaceans, and worms. In an aquarium setting however, they will often eat flake food or pellets that have been soaked in water for 30 minutes.

If your angelfish refuses to eat anything you offer it, try feeding it live brine shrimp or bloodworms once or twice a week until it begins to eat again. If your angelfish is sick or injured however, you should not attempt to force-feed it until its health has improved significantly.

  • Some angelfish species have been known to refuse to eat for weeks at a time when they are reproducing – this is normal behavior for these fish and no action should be taken unless there are other signs of illness such as signs of stress (clamped fins) or lethargy throughout the day.


They’re adaptable and will eat a variety of foods, but they are especially fond of insects. Supply live or frozen insects regularly to keep your angelfish happy and healthy.
