10 Aquarium Fish for Every Budget


5. Fancy Goldfish

Fancy goldish are double tailed goldfish that are typically more round in appearance. To own a single fancy goldfish, you need to have an aquarium that is at least 20 gallons (preferably more wide than high). However, since goldfish are highly sociable and require companionship, you will realistically be looking at 30 to 40 gallons to house a pair of fancy goldfish.
