Do Angelfish Eat Blood Worms?

Angelfish can eat blood worms, among all other different kinds of worms, as they are considered omnivores. Blood worms are rich in protein but also contain a large quantity of fat which can result in weight gain leading to sicknesses; therefore, it should be one part of a balanced diet. 

Knowing whether angel fish can eat blood worms is only the start of feeding them, as there are various advantages and disadvantages all fish owners should be aware of. Let’s look at the proper diets and feeding schedules of angelfish as well as other appropriate worms for consumption.

Is It Healthy For Angelfish To Eat Blood Worms?

Blood worms are a necessary addition to the diet of an angelfish as they are rich in iron and protein.

One of the accepted theories by researchers is that in the wild, angelfish eat their own eggs due to a protein deficiency; therefore, a healthy quantity of blood worms will give them the strength they require for optimum health.

The protein from blood worms will provide angelfish with amino acids to replenish their cells and aid them in growing at a natural pace.

Blood worms are also considered a nutritious meal for angelfish, meaning you will have no issue feeding them or excess food left over, causing an unnecessary filth build-up in the tank.

Not only are blood worms a ‘delicious snack’ for angelfish, but live blood worms also provide them with the opportunity of hunting, simulating a scenario in nature that will satisfy their primitive urges as it’s part of their primal instincts.

Although the advantages of the blood worms make them far more necessary in the angelfish’s diet than just a simple ‘treat,’ there are some risks involved that would be remiss to ignore.

What Are The Downsides Of Feeding An Angelfish Blood Worms?

Unfortunately, blood worms don’t contain all the vitamins and minerals angelfish requires making them an ill-advised primary source of nutrition. In order for angelfish to grow and breed properly, they will need a balanced diet that includes protein but does not solely consist of it.

In addition, blood worms are also notoriously known for being difficult to consume due to their head. Although this does not necessarily imply that angelfish will run the risk of choking, it does mean that processing the meat is much harder than usual, which can cause bloating when overfed.

Furthermore, there have been issues in the past of blood worms not being properly sterilized, which caused the fish to be exposed to consequent illnesses. However, sterilization is of more concern to owners who feed their angelfish live blood worms, as frozen ones tend to be free of harmful bacteria.

The most common concern regarding feeding angelfish blood worms is their regularity. Angelfish suffer from malnutrition due to an unnecessary increase of protein, so how much should you feed them, and how often?

How Often Can You Feed Angelfish Blood Worms?

Regarding the feeding of an angelfish, there are a lot of variables that you should keep in mind because all owners have different amounts of fish of different sizes in a single tank.

Various specialists in the field don’t wholly agree on the amount of food to feed a single fish at once, but all of them agree that overfeeding is a common mistake that new and experienced owners make.

Most specialists agree that fish should be fed once or twice daily with regular flakes and pallets but should only receive blood worms once a week.

The general rule is to give the fish as much food as they can consume within a time bracket of three minutes. If the angelfish takes longer than three minutes to complete all the food and is still consuming, then the quantity exceeds the limit.

Although three minutes is generally a safe rule, this might not be ideal concerning blood worms.

With blood worms, it’s better to feed them to the angelfish like a ‘treat’ and use it conservatively. Urge on the side of caution and let the fish enjoy small portions that aren’t entirely filling rather than becoming sick and constipated from overeating.

What’s The Difference Between The Types Of Bloodworms?

There is a significant difference between feeding fish live and frozen blood worms, but the convenience and storage space for the owner should also be considered. Let’s look at the main differences:

  • Live worms are the most nutritious and mentally stimulating for angelfish as they provide the opportunity for them to hunt, and as they are still alive, they contain a lot of cells and blood, which is healthy for the fish to consume.

Unfortunately, live blood worms are at high risk of carrying bacteria and parasites and don’t have an extremely long life span. As a result, you should buy from a breeder with a successful track record and immediately feed the worm to the angelfish within three days.

Make sure to properly clean the blood worms before feeding them and separate them from their container using a tweezer and a glove without exposing their contaminated water to your tank water.

  • Frozen worms, although not as nutritious as live worms, still contain all the needed qualities for a healthy protein-filled snack, and they are much more convenient to store.

Owners can safely store frozen blood worms for up to six months, and it only takes a few seconds for the worms to warm up enough for the angelfish to consume them comfortably.

Frozen worms are not as stimulating as live worms, but the risk of them carrying parasites and bacteria is much lower.

  • Freeze-dried worms will be the simplest way to provide angelfish with an adequate protein intake. The drying process does remove a lot of the nutrients, making them even less ideal than the frozen worms.

Still, the feeding process is much easier and includes an acceptable amount of protein the angelfish require.

Some freeze-dried containers are of lower quality, as other consumable parts will be included in the mix.

What Is Healthy For An Angelfish To Consume?

Angelfish are quite hardy animals and can eat a variety of different options, but the ideal is to combine them for a healthy diet.

Flakes and pallets should be their primary source of food, especially cichlid flakes, as they are filled with nutrients from algae, and some brands, have a combination of color and vegetable flakes.

Once you have a consistent flake brand, you can feed the angelfish daily; adding live foods at least once a week is advantageous to provide them with the necessary protein. Protein-filled foods can include bloodworms, white worms, mealworms, brine shrimp, and even small insects.

However, remember to buy live foods from a trusted and reputable source, as parasites and bacteria can cause a lot of damage to your angelfish.

If you are concerned about the dangers of feeding your angelfish the live foods mentioned above, you can also purchase them frozen or freeze-dried. Although the nutritional value will not be the same, it is still a healthy, protein-filled option.


Blood worms are an ideal addition to an angelfish’s diet; whether you feed them live or frozen, they will provide the fish with appropriate nutrition. However, the angelfish diet cannot solely consist of blood worms; any amount fed to them should be done conservatively.
