Important Note: It's essential to keep in mind that goldfish need a lot of space to thrive. A single goldfish needs at least 10 gallons of water, and multiple goldfish require even more space. Avoid overcrowding your tank, as this can lead to health problems and stress.
Consider your budget and the size of your goldfish before making your purchase. You can often find good deals on used tanks and equipment online or at local pet stores.
