They aren't really eating the pebbles, they are looking for food. Goldfish are scavengers and will eat anything they can find. Once they know it's not edible they will spit it out.
It won't harm them, but they typically don't eat it. Sometimes they might confuse it for food, but they normally spit it out immediately.
Yes of course you can From Pebbels
Yes they can because I tried it on some goldfish and they ate it.Besides, they will eat almost anything!!Yes they can but if you have little ones do not give them big pieces. The bread will make their tank dirty very fast though.
ants will eat spit if they have to
Yes it is perfectly natural behavior for a goldfish to eat its own eggs and/or fry. That is why you must sepperate the parents from the eggs/fry when you breed goldfish.
No. They eat goldfish flakes.
yes a axolotl can eat a goldfish
There are a great many plants that goldfish will not eat. Goldfish will not eat plants like trees for example.
Guppies don't get large enought to eat goldfish. They will eat anything they can fit in their mouth. The goldfish might eat your guppies though.-Melchisedek
What is more pertinent is, "What plants DON'T goldfish eat?"
Goldfish usually do not eat their own feces; sometimes they confuse it with food, but they will normally spit it right back out. It won't harm them since it's basically the byproduct of the food you feed them, but make sure you are cleaning your tank every week with a water change to remove all the waste.
