Common Goldfish
Common Goldfish come in several color varieties including orange, red, white, black, brown and combinations of any of these colors. All Goldfish varieties have been domesticated from wild carp.
Goldfish are members of the carp group and are generally quite hardy. Smaller goldfish do well in an aquarium of 30 gallons of water or more while young. However, goldfish can grow to 12+ inches and will eventually outgrow aquariums less than 100 gallons. Therefore, you must accommodate their growth needs over time. Goldfish aquariums should have a fine gravel bottom and hardy, cold water plants. Goldfish are diggers and can be messy so a capable filtration system is a must. Goldfish will also fare well in ponds with Koi and other Fancy Goldfish with similar water parameters.

Bought a red and white goldfish for my 55-gallon tank. It’s active and colorful. After a few months, I noticed it started digging, so I upgraded the filter. Now it’s thriving with some java moss and fine gravel. Good choice for beginners who plan to grow their tank over time.

Received a black goldfish and it’s been very calm and healthy. I keep it in a 75-gallon tank with a few plants. The fish seems to enjoy the gravel and doesn’t stress easily. Just make sure the filter is strong enough to handle the digging.

My family has had goldfish for years. This common variety is hardy and beautiful. We started with a 30-gallon tank and expanded to 100 gallons after the fish grew. The color combinations are vibrant and they’re a great addition to a pond or aquarium.
