Lindsey Stanton Profile Picture

By Lindsey Stanton


Green peas are an exceptionally healthy and beneficial vegetable to feed your goldfish. They can help with digestion, constipation, and sometimes mild digestive swim bladder-related issues. This makes them a very well-known and sought-after snack for goldfish among goldfish keepers.

They offer good nutritional value to your goldfish’s diet. Although they are such a good source of fiber, and most people will try to feed their goldfish peas as often as possible, it’s best not to overdo it. They should be treated as a snack and fed occasionally.

Peas can be fed alongside the main diet every now and then for added fiber to the diet. They can also be fed during medical fasting (for example, swim bladder issues brought on by digestion or constipation problems).

Before feeding your goldfish this delightful snack, you want to make sure you follow the correct steps to prepare the green peas appropriately for your goldfish. You should buy plain green garden peas without additives except for water. You can safely feed the premade tin garden peas or the bagged version of uncooked hard peas, which you will then have to boil.

How To Prepare Frozen Peas

  1. Take the frozen bag or container out of the freezer the night before you plan to feed it to your goldfish.
  2. Once it is completely defrosted, microwave it for 30 seconds
  3. Run the peas under cold water and wait for them to cool down.
  4. Deshell the peas.
  5. Proceed to squish the peas inside between your fingers.
  6. Drop the peas into the aquarium for your goldfish to consume.

Always wash your hands before handling your goldfish’s food, avoid serving frozen or hot peas to your goldfish, wait until the peas are at room temperature, and try to avoid over-feeding peas to your goldfish. If your goldfish gets messy, you may want to consider only feeding the peas before a water change and substrate cleaning by means of a gravel vacuum (siphon).

Tips for Feeding Peas to Goldfish with Swim Bladder Issues

It is important to ensure the condition you’re treating has to do with digestion or constipation. It is best to fast the fish appropriately and feed a whole deshelled pea to an adult goldfish twice a day, or a goldfish under 2 inches with half or a quarter of the pea twice a day, ideally in the morning and evening.

Do not fast the fish for longer than 3 days. It is best to seek medical help from your trusted aquatic vet or a knowledgeable goldfish keeper when you notice any sign of a swim bladder issue. Peas are not a go-to cure for swim bladder problems and should not be handed out as such.

Your goldfish will greatly appreciate the benefits peas have to offer, but you should serve them only as a snack to supplement a balanced diet.


Although peas are a great source of fiber, it’s best not to overdo it. They should be treated as a snack and fed only occasionally. Follow our steps above to make sure you feed peas to your goldfish safely!
