What is wrong with the fish?

i wouldnt doubt it but its been doing it for a while now

There are a few things it might mean: Your goldfish might have gas. Depending on if you use flakes that stay at the top of the water. Some air can into to the goldfish when it goes for a glup. Your goldfish could possible have a disease known as swim bladder disease. This disease will happen if the water quality is bad, overeats or from bacteria. You can go to a pet store and ask for swimming bladder medicine if you think your sister’s goldfish might have this.

aaww well the poor fish is old animals get old just like humans

would the gas thing affect the other fish in the tank also

It is swim bladder disease. I’m not sure if it will affect the other fish, but they tend to die from it. I had a fish with the disease and it died in a day O.O

It is constipated. It needs live food. black worms,blood worms, brine shrimp. Can also be frozen food. 1 to 2 times a weeks to keep him cleaned out

umm… i dont think i can do that it’s only a little gold fish

Just because it is a goldfish doesnt mean you can just barely take care of it. My boyfriend worked at an aquarium. he knows what he is talking about. Its still a living creature. i cant believe some people.

it died today

yeah poor thing died today :(
