Q&A for How to Prepare Fruits and Vegetables for Goldfish to Eat

They can, but don't feed too many fruits and vegetables to your fish. It's easy to cause buoyancy, indigestion, and bloat issues. In general, a quality flake or pellet diet explicitly designed for goldfish can suffice. Goldfish need plant matter, but they also need protein and vitamins. They can get all of these from quality goldfish foods.

Consider that your goldfish might have parasites. Its behavior might be defined as flashing.

Do NOT save food after it has been in tank water. It will start to ferment or grow bacteria - I got my whole tank sick once by using "saved peas." It is not worth the risk for a couple spoonfuls of food. Better to boil and shell peas, then freeze them in ice cube trays and thaw as needed. Make sure you thaw them, though. Don't drop ice cubes into your tank.

Yes, you can feed cucumber to your goldfish. A day at most, preferably not more than a few hours. I just chop it up and feed it tiny pieces so I don't have to worry about the water quality.

The vegetable needs to be soft, so steaming or boiling is always a good idea.

Peas are vegetables that sink and goldfish usually love them, however I wouldn’t try to get your goldfish used to eating food that floats, as when they try to eat the floating food they will gulp air at the same time, which can lead to problems and illnesses later on.

No. The broccoli is not soft enough for the fish to chew. You need to soften it up first, and cooking it is the best way.

That's a whole lot of banana! I guess if you've got 7 two-foot long Koi they might be able to handle it, but if you've got little tank fish, I'm gonna say that's way too much banana. Try this, the next time you are eating a banana, cut 7, 2mm slices (1/8 inch) and drop them in the tank.

No, because it contains oil, flavorings, and other things not suitable for any fish to eat.

No. Banana chips have too much sugar.

Because they're too hard. Goldfish do have teeth like us, and the skin requires some biting and chewing that they are not capable of.

It probably doesn’t hate you; however, when a goldfish is introduced to a new tank it will be a very stressful time. Just be patient and give it a bit of time to settle in and it will soon start to like you.

Lemons and limes should not be given to fish.

No. You cannot feed them seeds. You can only give them the chopped up flesh.

No, you should not feed them rice.

Unless it is formed into a gelatin, no, it will pollute your water.

Your water may be polluted, or it may be regular bubbles from your fish breathing. Are you cleaning the tank daily?

Shell the peas first, but if they are small enough for the fish to nip and eat at, no cutting should be needed since they are soft enough. Bananas should be cut into small cubes, like the size of a short pinky nail (on hand).

Yes, they are omnivores, but I recommend feeding them freeze-dried food, like brine shrimp and blood worms.

Bananas should be cooked and chopped small before you give the fruit to your fish. Bok choy, cabbage and broccoli are also popular choices. It’s fine to mix cooked and uncooked food together in your tank.

You may use commercial fish food for feeding, but you can also feed "crunchies," dry mealworms or goldfish food as shown on the package to feed live mosquito larvae. You'll want to do some research first to determine the best fish food to use. Make sure to check the label. Some will say that the eggs may not hatch unless you feed live fish food. You should use enough food to cover at least the top third of the aquarium.

The majority of male and female goldfish will grow to the same size. It is usually easiest to gauge their age by looking at their coloration. As a female grows older, the color of her scales will become more vibrant and gold. However, if your male goldfish is growing too slowly, their color will gradually dull, which signifies that they are young and should be encouraged to reproduce.

Yes, you can but make sure to cool it down with cold water afterward. Also, make sure to cut them into tiny pieces. Don't have any oil or flavoring in the pot.

Yes, but you have to boil it to soften it first. Broccoli has vitamin C, which is great for your goldfish.

No. Feed him store bought flakes or pellets or live food like brine shrimp and bloodworms. Once every night.

Try fish flakes, which your fish can consume and digest much more easily.

Cut the steamed peas and banana into 2mm pieces. Probably about 3 pieces of food for each fish would work best.

Yes, you can, but not too often. Make sure they are finely chopped and soft.

You can feed it flakes, various types of fruits that are chopped, cleaned, peeled, soft, and/or softened. Same with veggies. Just make sure to not over feed.

Yes, you do need to soften the lettuce or chop it up, or else the fish may not be able to chew/digest the food or even put it in its mouth.
