Goldfish and cichlids have different water temperature requirements, making it unwise to keep them together. But what about their food? Can goldfish eat cichlid pellets? And vice versa? Let’s find out.

Can Goldfish Eat Cichlid Pellets?

Yes, goldfish can consume cichlid pellets in the short term without immediate harm. However, it’s not advisable to make it a habit. Goldfish and cichlids have distinct nutritional needs and metabolisms. It’s best to stick to food specifically formulated for goldfish.

Will Goldfish Eat Cichlid Food?

Indeed, goldfish readily eat food intended for cichlids, whether it’s flakes, pellets, or live food. They happily accept almost any food meant for tropical fish. But just because they can eat it doesn’t mean they should consume cichlid food regularly.

Why Shouldn’t Goldfish Eat Cichlid Food?

The crucial difference between food for tropical (warm-water) fish like cichlids and cold-water fish like goldfish lies in the protein content. Cichlid food typically has a higher protein concentration than what goldfish require.

In warm water, fish can metabolize protein much faster, resulting in less excretion of dissolved protein waste and less pollution. However, goldfish, thriving in cold water, cannot metabolize protein as efficiently as cichlids. This not only affects their overall health but also pollutes the water more quickly.

There’s a catch, though. Most goldfish raised in farms and homes are kept in higher temperatures than ideal. While the recommended water temperature ranges from 68° to 74°F (20-23°C), many goldfish are exposed to temperatures at the higher end of the spectrum.

At these temperatures, goldfish not only accept cichlid or tropical food but also metabolize it quicker and utilize the ingredients more efficiently. Nonetheless, goldfish still require less protein in their diet compared to cichlids.

Let’s compare the nutritional breakdown of goldfish pellets and cichlid pellets from the same brand.

While the nutritional concentration is almost the same, goldfish pellets contain 7% more protein than cichlid pellets.

How Often And How Much To Feed Goldfish?

The ideal feeding frequency for goldfish is 2-3 quick meals throughout the day. To prevent overfeeding, give them only what they can finish within 2-3 minutes. Always remove any uneaten food promptly to avoid increasing ammonia and nitrite levels in the tank.

Overfeeding is indeed harmful to your pet’s health and pollutes the water. However, underfeeding is equally dangerous, if not more. Malnourished fish experience stunted growth, lead poor lives, and have shorter lifespans.

For example, vitamin A deficiency in goldfish can cause conditions like anemia, dropsy, and internal bleeding. Similarly, vitamin C deficiency can result in eye hemorrhage and a deformed spine.

Now, let’s discuss the nutritional requirements of goldfish in more detail.

A Goldfish’s Nutritional Requirements

Goldfish are omnivores, mostly subsisting on plant-based diets in the wild but occasionally indulging in critters and small fish. Their diet should include essential nutrients such as protein, vitamins, minerals, and fat. However, they don’t require as many carbohydrates and fiber as some other fish.

Protein is vital for goldfish growth and development. Commercial goldfish food highlights this requirement by including a significant amount of protein. Young goldfish need at least 45% protein in their diet, while older fish can manage with 30% protein. Plant-based protein is preferable as it is easily digested.


Goldfish convert fat into energy, making fat intake crucial for them. Their diet should consist of approximately 5-10% fat. Animal fat, such as fish oil, is preferred over plant fat.


Vitamins are essential for goldfish to lead healthy and long lives. Their vitamin requirements are similar to ours, mainly encompassing vitamin A, C, D, K, and folic acid.


Goldfish obtain a good portion of the minerals they need from the water. However, it’s still important to reinforce certain minerals like iron, magnesium, and zinc to ensure optimal health.

Low Carbs And Fiber

Goldfish require significantly less carbohydrates and fiber in their diet. Commercial goldfish food labels indicate low concentrations of fiber, often labeled as “ash.” Fiber should not exceed 10% of a goldfish’s diet, as it can inhibit the absorption and retention of essential nutrients. Likewise, excessive carb intake deposits in the liver and compromises the fish’s health, so carb content should not exceed 10%.

What Do Goldfish Eat In The Wild?

Goldfish are opportunistic omnivores and greedy eaters in the wild. Their diet includes plants (fresh and decayed), small crustaceans, insects, larvae and pupae, fish eggs, zooplankton, and detritus.

What Do Goldfish Eat In Captivity?

As a staple diet, provide high-quality sinking pellets or flakes for your goldfish and supplement their nutritional needs with occasional treats. Common treats include brine shrimp, tubifex worms, mosquito larvae, bloodworms, and daphnia.

Household Food For Goldfish

You can also offer the following household foods to your goldfish:

  • Peas
  • Carrots
  • Lettuce
  • Zucchini
  • Spinach
  • Grapes
  • Apples
  • Garlic
  • Oranges
  • Beans
  • Corn
  • Broccoli
  • Rice
  • Cucumber

Remember to boil these foods and chop them into small pieces before feeding them to your goldfish.

Different Dietary Requirements Of Common/Single Tail And Fancy Goldfish

Single tail goldfish have more robust digestive systems compared to fancy, ornamental goldfish. They can consume a more varied diet, including both sinking and floating food. Fancy goldfish have compacted and misplaced organs, which impact their digestion. You need to be more selective about their diet to avoid potential health issues.

Frequently Asked Questions

Can Goldfish Eat Tetra Food?

Goldfish can safely consume pellets or flakes meant for tetras, but it’s important to note that tetras require a higher protein content in their diet. Goldfish, being primarily plant-based eaters, should ideally consume food tailored to their species to meet their nutritional needs.

Can Goldfish Eat Betta Food?

Goldfish can eat betta food occasionally to supplement protein intake. However, betta food often contains more fat than goldfish require. Additionally, goldfish prefer sinking pellets, while most betta food floats. Feeding goldfish betta pellets can lead to water pollution if they wait for the food to sink before eating.

Can Goldfish Eat Catfish Food?

Goldfish can safely consume catfish food occasionally, as the nutritional content is similar. However, remember that catfish are tropical fish, so it’s best not to make it a habit.

Final Words: Can Goldfish Eat Cichlid Pellets?

The answer is both yes and no. While goldfish can occasionally eat cichlid pellets due to their similar ingredients and nutritional content, their different metabolisms set them apart. Goldfish, living in lower temperatures, may not efficiently metabolize the high protein content of cichlid pellets. Therefore, it’s best to stick to food specifically formulated for goldfish to ensure their well-being.
