The reputation of goldfish dying quickly is often due to poor care. The lifespan of goldfish in captivity can extend beyond 10 years.

The size of a goldfish tank can affect the growth of the goldfish. A larger tank provides more space for the goldfish to swim and grow, leading to healthier and potentially larger fish. In contrast, a smaller tank can restrict the fish's movement and growth, potentially stunting their development.
A 5-gallon tank is not recommended for keeping a goldfish. Goldfish require a larger tank size to thrive, ideally 20 gallons or more for a single goldfish. A larger tank provides more space for the goldfish to swim and grow, as well as better water quality.

It may just be getting used to the surroundings that you have put it in. Or if you have had it for a day or two it may need food or its bowl/tank cleaning out.
The size of a tank can affect the growth of goldfish. A larger tank provides more space for the goldfish to swim and grow, allowing them to reach their full potential size. In a smaller tank, goldfish may be stunted in growth due to limited space and water quality issues.
Regardless of the type or size of goldfish the minimum acceptable size of an aquarium for a goldfish is 30 gallons. Buy a tank that is at least 30 gallons if you plan to have goldfish. You can comfortably fit 3 goldfish in a tank this size but no goldfish in a tank any smaller. Goldfish are essentially pond fish and need lots of space to swim; they will not thrive in a small aquarium.
Goldfish are moderately inactive fish. They will spend much of their time just floating or sitting at the bottom.
That means your fish is ill
