Goldfish care often involves more than just food and shelter—but the first necessity you’ll need before purchasing your pet is a goldfish bowl or aquarium. The size of your habitat typically influences how large your goldfish will grow—as long as one foot, and how long they will live—on average, about 10 to 15 years, but as long as 30 years. These fish can grow according to the size of their aquarium, which correlates to how much food they consume.
Goldfish food will also be a necessary supply for your fish. These aquatic pets mainly eat fish flakes or pellets and—as long as it’s food specifically for goldfish—different brands or varieties of flakes or pellets typically won’t make much of a difference. However, many pet goldfish enjoy a snack of bloodworms, tubifex worms or brine shrimp.
You’ll also need supplies to maintain the water quality in your goldfish bowl or aquarium, including water test kits and other essentials mentioned in the section below. At Petco, we also carry less common solutions for goldfish health and wellness like habitat dividers and antibacterial medications that you may find useful for your pet.
