Goldfish are a popular choice for beginner fishkeepers due to their hardiness and relatively low maintenance requirements. However, there are a few things to keep in mind when choosing a goldfish to ensure that you get a healthy fish that will thrive in your aquarium.
First, it is important to choose a goldfish that is the right size for your aquarium. Goldfish can grow to be quite large, so it is important to make sure that you have an aquarium that is big enough to accommodate their adult size. A good rule of thumb is to have at least one gallon of water for every inch of goldfish.
