How Often Should You Feed Goldfish? Ideal Feeding Schedule

If you've ever had goldfish, you've probably wondered how often you should feed them. Goldfish should be fed 1-3 small portions per day, with portions no bigger than the goldfish's eye. Make sure to only feed them what they can eat in 2-3 minutes to prevent overfeeding and dirty water.

Goldfish are known for being pretty tough fish, but how often you feed them and the amount you feed them are important for their overall health and well-being. We'll go over information from veterinarians and best practices for maintaining your aquarium to make sure you have everything you need to know to set up the best feeding schedule for your fish. This will help you make sure you're feeding them the right amount of food while avoiding some of the most common mistakes that can put your fish at risk.

How to Feed Goldfish in an Aquarium

Feeding goldfish in an aquarium setting is a bit more complicated than it might seem. To start, make sure the food you're feeding is small enough for your goldfish to eat. According to Aqueon, "The size of the food you feed should match the size of your fishes' mouths," and this is especially important for fancy goldfish, which have smaller mouths than common goldfish.

After that, think about your goldfish's natural tendencies and feed them accordingly. Next Day Koi suggests using a turkey baster to gently squirt some [food] lower into the water column for mid-water and bottom feeders, which will help ensure that all of your goldfish get enough to eat.

No matter how you feed your goldfish, make sure to remove any uneaten food after 2-3 minutes to avoid water quality issues. Aqueon suggests using a net or siphon to do this, as leftover food can decay and cause water quality issues.

To make sure your goldfish are getting all the nutrients they need, feed them a mix of high-quality pellets, flakes, and freeze-dried foods like brine shrimp or bloodworms, as well as fresh vegetables like peas or zucchini, according to Complete Goldfish Care. Dr. Erik Johnson also recommends "switch[ing] foods a lot" to make sure goldfish get a variety of nutrients in his veterinary advice.

Finally, make sure to feed your goldfish at the same time every day, but consider fasting them one day a week to help with digestion, which, according to Aqueon, will help fish "to clear their digestive systems." If you follow these guidelines, your goldfish will get the nutrition they need to be healthy and happy.

How Much to Feed Your Goldfish

If you want to be more exact, you can weigh your goldfish on a kitchen scale and then feed them 1% of their body weight per day, dividing that amount into multiple small feedings as suggested by Web Goldfish. Pay attention to how much your goldfish eats and adjust the amount you feed them as needed to make sure you aren't overfeeding or underfeeding them. Feeding your goldfish multiple times a day will also help ensure that their food is digested properly and that your tank's water quality stays high.

Keeping Your Goldfish Tank Clean and Healthy

As noted by The Spruce Pets, weekly partial water changes (25-30%) and gravel vacuuming will help remove waste and keep the water quality up. wikiHow adds that an aquarium vacuum can be used to suck up any debris that's become dislodged from the gravel.

You'll also want to make sure you clean the filter media and decorations regularly, although The Spruce Pets suggests doing this on a rotating basis to avoid removing all of the beneficial bacteria. It's also important to keep an eye on water parameters like pH, temperature, and ammonia/nitrite levels and adjust them as necessary to keep your goldfish healthy, according to Aquarium Co-Op.

Every 4-6 weeks, The Goldfish Tank suggests doing a full tank clean, which includes rinsing the substrate and removing algae from the tank walls. It's important to use the right tools, including a siphon, algae scrubber, and dechlorinator, to ensure that your tank is cleaned properly and safely.

How to Tell If You're Overfeeding or Underfeeding Your Goldfish
