HELP MY GOLDFISH!!! It won't eat! :((?

It seems like you're offering food too often. Try skipping a day or two of feeding so the fish is hungry and will eat. In nature, they often don't eat every single day, so skipping a day or two is fine. Feeding every other day or every two days is okay. Make sure to only feed as much as your fish can eat in about a minute. If he eats it all then give him a bit more.

If that doesn't work you can get some frozen fish food like blood worms or a tropical mix and try that.

If there's too much uneaten food in the tank it can cause toxins to build up in the tank and kill the fish.

10 gallons will be far too small when the fish grows, I hope you realize that. The best tank for a goldfish under 13 inches is a 75 gallon, and they'll outgrow even that. But, at least he's in a tank.

You don't need extra chemicals that remove ammonia, nitrite, or nitrate. All you need is water conditioner. A water testing kit is another important tool along with a gravel vacuum.

And on the subjected of food; just be patient. The fish is unsure about the new food. It'll eat it eventually. If a week goes by and the fish doesn't eat, try offering frozen blood worms. You might spark its attention then.

Lastly:

Change 50% of the water every week.

Test the water for ammonia, nitrite, and nitrate every week until it cycles.

After it cycles, test the water every two weeks and do weekly 25% water changes.

Never change the filter media.

Never rinse the filter media in tap water.

When it gets dirty, rinse the media in old tank water.

Use the gravel vacuum whenever you change water.

Never remove the fish from the tank.

Avoid large water changes.

Do not get another goldfish unless your tank is 40 gallons or more.

Keep the ammonia and nitrite levels at 0.

Try a different brand of pellets, and try soaking them in garlic extract for a minute or so before feeding. Try frozen brine shrimp or blood worms. If all else fails, google how to culture bring shrimp, blood worms or wingless fruit flies to stimulate the fish to eat.

Stop feeding. That's it, you are overfeeding the tank, stop it.

Eventually it will eat, don't just keep putting food in the tank.

Try again in a couple days.

You need a 30 gallon tank and you need temps at 65 degrees - the fish is "cooking"

Try another food and ask pet store

try vegetables it would be great
