Best Goldfish Food and What Not To Do

best food for goldfish including organic options

Goldfish act as if they’re are always hungry and tend to eat as much food as offered. It’s up to the owner to regulate the amount and types of food given at feeding time.

1. Feeding Tips

Feeding your goldfish is an easy process because they’re omnivores. This means goldfish will eat not only plants but animal tissues as well.

Goldfish aren’t choosy when it comes to what they’ll eat. If the food item is small enough to fit into their mouth they’ll consume it with very few exceptions. Even though they’ll eat anything, not everything is necessarily good for goldfish.

How often should you feed goldfish?

It’s best to feed 2 times a day.

If feeding twice a day feed an amount of food that can be consumed within 2 minutes.

If feeding once a day only feed the amount they can completely consume in 5 – 10 minutes.

Don’t overfeed. It’s easy to overfeed goldfish. They like to eat and always appear to be hungry.

Feed goldfish at a regular time daily

2 reasons regular feeding time is important are

  1. you’ll find the fish eager and waiting for their meal, and
  2. it’s easier to spot a fish that shows no interest in feeding indicating something is wrong.

Mealtime is essential for healthy goldfish. Taking care of their needs should be handled properly every day. Remember, they’re totally dependent on you.

Feeding goldfish nutritious food doesn’t require a lot of money.

They eat just a small pinch of food a day and are the most inexpensive of all pets as far as their nutritional needs are concerned. So it’s inexcusable for your goldfish to be malnourished and unhealthy when quality food is readily available.

2. Goldfish flakes

The most common food is goldfish flakes and many first time goldfish owners stay with the obvious choice of goldfish flakes. Cheap and fuss free, quality flakes meet nourishment requirements.

How to feed: Start by offering goldfish a small pinch of food. Continue offering as much food as the fish can eat in a 2-minute period, but only small amounts at a time. If any food remains in the water, try to remove it because this will stop excess food polluting the water.

Goldfish flakes are available in a variety of conveniently sized packages.

Some owners don’t realize that goldfish eat food other than flakes. Although flakes are a good choice a variety of food is beneficial and can be included in the goldfish diet.

3. Goldfish pellets

Goldfish pellets are readily available. Buy quality as some may not be nutritious enough to be used for every day feedings.

How to use:

  1. The pellets should be pre-soaked to ensure they don’t expand inside the goldfish. If the pellets expand after being eaten they’ll cause constipation issues.
  2. Goldfish will normally eat the pellets once or twice a day, depending on the size of the fish. The amount given will also vary. Larger fish may eat 8-10 pellets, while smaller fish will not be able to eat near that many.

Check ingredients and labels to see if the pellets are meant for mealtime or simply a snack.

4. Algae wafers

Optimized vegetable and protein content make these power packed wafers one of the best foods. They provide your goldfish with the nutrients for optimal health and growth.

Goldfish like to eat algae and you’ll find them snacking on green algae that builds up in the fish tank.

5. Repashy Soilent green gel food

How to use this super food: Mix a ratio of 1 : 3 water and stir on a stove top until boiling, remove. Alternatively place in a microwave, bring to the boil and remove. Stir well.

Pour into molds or a container and as Repashy cools it will firm up.

Treat it as a fresh food, therefore what’s not used immediately needs to be refrigerated (up to 2 weeks) or frozen (up to 6 months).

The natural behavior of river carp (these are ancestors of the goldfish) is to scavenge for algae on the bottom of the river. The technique below stimulates natural instincts

Something interesting to try. While Repashy is still hot pour a small amount over the rough surface of a rock taken from the tank. Allow to cool.

Return the rock to the tank. The fish will smell the food and it stimulates their natural foraging instincts. It may take a little time for them to get used to it and feed. Our experience is that they’ll love it.

Note: Don’t leave the rock in the tank indefinitely. Just let the fish graze for a little while and then remove it. You can wrap the rock in cling wrap and store in the refrigerator. It lasts about 5 days in the fridge.

6. Brine Shrimp eggs

Brine shrimp eggs are the food of choice for fry and developing fish.

8. Fruit and vegetables

Fresh nutrients found in fruits and vegetables also make great additions for the goldfish diet.

The benefits

  • Greens are good for the digestion system
  • Peas help resolve constipation issues in goldfish.
  • Fish enjoy the variety

   *Lettuce are peas particularly are good choices.

Before feeding them they’ll need to boiled or softened in some way. Peas should be cooked, skins taken off, and slightly mashed before being fed to goldfish.

The fish will nibble on the pieces even if they’re larger than their mouths.

Some options to try: Peas, carrots, squash, lettuce, melons, and bananas are some of the fruits and vegetables.

9. Aquatic plants

Aquatic plants are also something that goldfish eat.

Anacharis plants tend to grow fast, are inexpensive, and goldfish love to eat them. The plants can be placed directly into the tank.

Note that you’ll have to replenish the plants as fish tend to eat them up and pull them apart.

10. Warning

Pellet food that’s not soaked before feeding can expand in the digestive tract of the goldfish. This can cause serious problems as it produces blockage and constipation issues.

If food is stuck on the top of the fish tank, the goldfish can ingest air and this causes constipation issues as well.

Goldfish enjoy frozen and live food. Eg live brine shrimp, blood worms, earthworms, krill, other shrimp and worms. However by introducing live foods you run the risk of introducing infectious diseases to your tank.

Frozen food provides the same benefits as live food. A variety of frozen brine shrimp, tubifex worms, or mosquito larvae is available.

Goldfish eat just about anything that’s put in their tank. However, some things can be harmful. It’s important to feed only what is recommended for goldfish.

Overfeeding can cause swim bladder problems and constipation issues. These can be dangerous and take time to clear up.

Feeding goldfish is usually viewed as a very simple task. Although this is true, providing a variety of food that’s high in carbohydrates keeps goldfish healthier and living longer.
