What Do Angelfish Eat?

Angelfish can be fed various types of food. Here are the most common ones with some useful feeding instructions:

1. Brine Shrimp

Angelfish, being omnivores, relish brine shrimp as a part of their diet. Brine shrimp provide essential nutrients and are an excellent source of protein.

Live or frozen varieties are readily consumed by angelfish, stimulating their natural hunting instincts.

Feeding Instructions:

• Feeding Amount: For adult angelfish, feed about 6-10 brine shrimp per fish, ensuring they are small enough to be consumed easily.
• Feeding Frequency: Offer brine shrimp 2-3 times a week, combined with other foods for a balanced diet.
• Tip: Always opt for high-quality, parasite-free sources, and thaw frozen brine shrimp before feeding.

2. Bloodworms

Bloodworms are another favorite for angelfish and can be a treat due to their high protein content.

They are particularly good for conditioning angelfish before breeding. However, they shouldn’t be the sole diet, as overfeeding can lead to obesity.

Feeding Instructions:

• Feeding Amount: For each adult angelfish, provide around 4-6 bloodworms, ensuring they are an appropriate size.
• Feeding Frequency: Introduce bloodworms to their diet 1-2 times a week, but not daily.
• Tip: As with brine shrimp, purchase from reliable sources to prevent potential diseases, and always thaw if using frozen bloodworms.

3. Tubifex Worms

Tubifex worms are a rich food source that angelfish usually love.

They’re packed with protein and can aid in the growth and vitality of your fish. Yet, due to potential contamination risks, they should be given cautiously.

Feeding Instructions:

• Feeding Amount: A small clump, roughly the size of a pea, is sufficient for a couple of adult angelfish.
• Feeding Frequency: These can be given once a week, but always ensure they are clean and from a trusted source.
• Tip: Consider buying the freeze-dried version to minimize the risk of transmitting parasites or diseases to your angelfish.

4. Mysis Shrimp

Mysis shrimp are small, nutritious, and loved by many freshwater fish, including angelfish. 

They are rich in essential fatty acids and other nutrients, making them an excellent choice for a balanced diet.

Feeding Instructions:

• Feeding Amount: For each adult angelfish, offer around 5-8 mysis shrimp, depending on their size.
• Feeding Frequency: Mysis shrimp can be provided 2-3 times a week as part of a mixed diet.
• Tip: As always, opt for parasite-free sources and, if using frozen mysis, ensure they are thawed before feeding to your angelfish.

5. Daphnia

Daphnia, commonly referred to as “water fleas,” are an excellent source of roughage that can help prevent constipation in fish.

They are tiny, but their movement in water can trigger the hunting instincts of angelfish.

Feeding Instructions:

• Feeding Amount: A small pinch, enough that it can be consumed in under 5 minutes, is ideal for a group of adult angelfish.
• Feeding Frequency: Introduce daphnia 1-2 times a week to ensure variety in the diet.
• Tip: Daphnia can be an excellent choice to stimulate sluggish eaters due to their movement. However, make sure they come from clean sources to avoid introducing contaminants.

6. Beef Heart

Beef heart is a contentious food in the aquarium hobby.

While it’s packed with proteins and can promote growth, it’s not a natural food for angelfish and can be fatty. Use sparingly and ensure it’s finely chopped or ground.

Feeding Instructions:

• Feeding Amount: A piece roughly the size of a small pea is enough for 2-3 adult angelfish.
• Feeding Frequency: Limit beef heart in the diet to once every 1-2 weeks at most.
• Tip: Always prepare the beef heart by removing any fat and ensuring it’s fresh. Overfeeding can lead to fatty deposits in the fish, so moderation is key.

7. Flakes

Fish flakes are one of the most common foods for aquarium fish. They are formulated to provide a balanced diet, containing a mix of proteins, fats, and essential vitamins.

They float at the surface, which can encourage angelfish to feed from the top.

Feeding Instructions:

• Feeding Amount: Offer enough flakes that angelfish can consume within 2-3 minutes without leaving excess.
• Feeding Frequency: Flakes can be a daily staple, but always ensure you’re rotating with other food sources for variety.
• Tip: Store flakes in a cool, dry place to retain their nutritional value. Wet or damp flakes can lose nutrients and potentially grow mold.

8. Pellets

Pellets come in various sizes and can sink, allowing angelfish to eat from mid-water or the bottom.

They are denser in nutrients compared to flakes and are often used to ensure fish get a hearty meal.

Feeding Instructions:

• Feeding Amount: For adult angelfish, 3-5 medium-sized pellets per fish are usually appropriate. Ensure pellets are small enough to be swallowed easily.
• Feeding Frequency: Pellets can also be a daily staple, but remember to incorporate other food types for a diverse diet.
• Tip: Always choose high-quality pellets designed for cichlids or similar species, ensuring they have a balanced nutrient profile suitable for angelfish.

What Vegetables Can Angelfish Eat?

While angelfish primarily eat protein-based foods, they can occasionally benefit from small amounts of certain vegetables, which can offer added vitamins and fiber.

Here’s how you might incorporate these vegetables into an angelfish diet:

1. Carrots

Carrots are rich in vitamins and can be a crunchy treat for angelfish. However, they aren’t a natural part of their diet and should be given in moderation.

• Feeding Amount: Offer tiny, finely grated pieces, about a pinch for 3-4 adult angelfish.
• Feeding Frequency: Carrots can be given once every two weeks or less frequently.
• Tip: Always blanch the carrots to soften them, making it easier for the angelfish to digest.

2. Broccoli

Broccoli is rich in essential vitamins and can be an occasional supplement for angelfish, helping with digestion due to its fiber content.

• Feeding Amount: A small floret, finely chopped, is sufficient for a group of 4-5 adult angelfish.
• Feeding Frequency: Offer broccoli once every two weeks or less.
• Tip: Blanch the broccoli to soften it. This process also helps in removing any pesticides if not using organic broccoli.

3. Spinach

Spinach provides a good source of vitamins and minerals and can be readily accepted by angelfish when prepared correctly.

• Feeding Amount: One small, blanched spinach leaf, torn into pieces, can feed a group of 4-5 angelfish.
• Feeding Frequency: Introduce spinach into the diet once every two weeks or even less frequently.
• Tip: Always use fresh spinach, and ensure it’s thoroughly washed. Blanching not only softens the spinach but also reduces the oxalic acid content.

4. Cabbage

Cabbage can be a source of vitamins for angelfish, though it’s not a common food. If you choose to feed cabbage, ensure it’s soft and easily digestible.

• Feeding Amount: A small leaf or portion, finely chopped, is enough for a group of 4-5 angelfish.
• Feeding Frequency: Cabbage can be introduced once every three weeks or less.
• Tip: As with the other vegetables, always blanch the cabbage to soften it and to ensure it’s free from pesticides if not using organic sources.

5. Peas

Peas are a popular choice among aquarists for various fish species, including angelfish. They help prevent constipation and are easy for fish to digest when prepared properly.

• Feeding Amount: One de-shelled, blanched pea, mashed or broken into small pieces, can be shared among 3-4 adult angelfish.
• Feeding Frequency: Peas can be offered once a week, especially if you suspect digestive issues in your fish.
• Tip: Always remove the outer skin/shell of the pea after blanching. This makes it easier for angelfish to consume and digest.

6. Cauliflower

Cauliflower, like broccoli, is dense in nutrients. When softened, it can be an occasional treat for angelfish, although it’s not a natural part of their diet.

• Feeding Amount: A small floret, finely chopped, can feed a group of 4-5 adult angelfish.
• Feeding Frequency: Offer cauliflower once every three weeks or less frequently.
• Tip: Ensure the cauliflower is blanched to soften it and remove potential pesticides if not using organic sources.

7. Lettuce

Lettuce, especially darker varieties like romaine, can be a source of vitamins. However, it’s not very nutrient-dense and can be given sparingly to angelfish.

• Feeding Amount: One small leaf torn into pieces can feed a group of 4-5 angelfish.
• Feeding Frequency: Lettuce can be introduced once every two weeks or less frequently.
• Tip: Opt for organic lettuce to minimize pesticide risks. Blanching isn’t strictly necessary for lettuce, but it can make it more palatable.

What Do Angelfish Eat in the Wild?

In the wild, angelfish predominantly consume small invertebrates and crustaceans. They are opportunistic feeders, scouring the water column and plants for anything they can catch.

• Small Invertebrates: Angelfish hunt for tiny creatures like insect larvae, which are abundant in their native South American habitats.
• Crustaceans: They enjoy feeding on small shrimps and other minute crustaceans that thrive in freshwater environments.
• Plant Matter: While primarily carnivorous, angelfish might nibble on algae or other aquatic plants, though this constitutes a minor portion of their diet.

Commercially Prepared Food for Angelfish

Commercial foods for angelfish are specifically formulated to meet their nutritional needs and mimic their natural diet.

These foods come in various forms and are packed with essential vitamins and minerals. Here are some common ones that I usually recommend:

• TetraCichlid Cichlid Flakes (link to Amazon): This flake food is designed for cichlids, including angelfish, and offers a balanced diet with an optimal protein-to-fat ratio for healthy growth.
• TetraCichlid Floating Cichlid Sticks (link to Amazon): These floating sticks provide a hearty meal and cater to angelfish that prefer to feed at the water’s surface, replicating the floating insects they’d chase in the wild.
• San Francisco Freeze Dried Bloodworms (link to Amazon): An excellent treat for angelfish, these freeze-dried bloodworms offer high protein content and can be vital for color enhancement and conditioning.

How Much Food Should You Give Angelfish?

Angelfish should be fed a quantity they can finish within 2-3 minutes, ensuring no leftovers. Overfeeding risks poor water quality and angelfish health issues.

• Observe and Adjust: Initially, offer half a teaspoon of flakes; if consumed in under a minute, add an extra quarter teaspoon next time.
• Varied Diet: Offer 3-5 bloodworms per fish; if they eat them quickly, next time, provide 5-7, but always observe their pace.
• Juveniles vs. Adults: For rapidly growing juveniles, offer food amounts 10-15% more than for adults but still within the 2-3 minute rule.

What Should You Do if Your Angelfish Isn’t Eating?

If your angelfish isn’t eating, it’s a sign of potential stress, illness, or environmental issues. It’s crucial to act promptly and assess the possible causes.

• Water Quality Check: Test the water for ammonia, nitrites, and nitrates. Ensure parameters are within safe levels; for instance, ammonia should always be at 0 ppm.
• Observe Behavior: Check if the fish is lethargic, has clamped fins, or shows unusual swimming patterns, indicating potential health problems.
• Dietary Variation: Sometimes, a change in diet helps. Try offering live brine shrimp or a different brand/type of pellet to entice them.
• Tank Environment: Ensure the tank isn’t overcrowded and that the angelfish isn’t being bullied. A 55-gallon tank for a pair of adult angelfish is ideal to prevent stress.

How Long Can Angelfish Go Without Eating?

Healthy adult angelfish can survive without food for up to 10 days, though it’s not recommended. Extended fasting can lead to stress and health complications.

• Short Absences: For vacations under a week, healthy adult angelfish will manage without food, but ensure they’re well-fed before you leave.
• Juvenile Concerns: Younger angelfish have a faster metabolism. They shouldn’t go without food for more than 3-4 days.
• Auto-feeders: If away frequently, consider an automatic fish feeder to ensure consistent meals. Ensure it’s calibrated to avoid overfeeding.
