Great, long lived fish...
but you better have some cash.
I see that PetSmart recommends 29+ gallons. Well I have to disagree respectfully.
Goldfish should be kept 2+. They grow pretty big and are pretty active fish. 50 gallons is what I would say is ideal for 2 goldfish. Add 10 gallon (rule of thumb of mine) for each additional goldie. You also want a good filter system as they are extremely messy and too much gunk in their tank is a quick way of getting them sick despite them being very hardy.
I understand to some this seems excessive to some, but considering some goldfish can live 20 years (the average is 8-10-ish though) you may want to invest in your friends.
On a huge positive side they often come with huge personalities and some will even interact with their owners. Other than an Oscar these are probably my favorite fish.

The Gold Standard
Goldfish may be too ordinary for most people, but don't sell them short. They're extremely colorful, very social, active and visible. They're also very hardy and durable - able to withstand varying water conditions for those of us who don't have the time to check water all the time. And while they are indeed eating and pooping machines, limiting their diet and adding a bottom feeder or two will keep this in check.
While the larger fancy goldfish fetch pretty high prices now (over $30 each), it's often best to start with a smaller $5 fish and simply wait until they grow. It won't take long...
I've found that it's best to keep two fancy goldfish together as a pair. By themselves, they can become listless and any more, and cleaning/maintenance becomes an issue.
Goldfish will live for many years in the right environment and a tank heater is not required. In fact warmer tropical temperatures will shorten their lives. For some variety in a goldfish tank, you can add small Koi, Minnows and Catfish. They will all do well together.
When I pick a goldfish, I choose one that has a stocky build, straight spine, good fin margins and vibrant colors. I check carefully for mouth damage or kinked fins, which can indicate mishandling.
I have a beautiful calico telescope eye, which are very interesting to watch, however know that they actually cannot see that well, so make sure they get enough food, if there's other fish competing for the flakes.
Also change the filter and do partial water changes often to make sure they stay healthy and active for years. Goldfish are self-limiting and if bought small, will not outgrow the tank.

I love my fancy goldfish!! I bought an Oranda and Lionhead from Petsmart and it was the best decision. To begin, these fish have great active personalities, they recognize you and have great characters. In addition, they are HUGE. They last about 10 years if kept healthy. I would recommend these, they are worth the price! They're gorgeous.
As a side note: Although they are hardy fish, be sure to read up on the tank sizes for them. They will not grow or be the healthiest they can be if their environment is too small. Also, they are prone to swim bladder disease and other sicknesses if you're not careful.

I absolutely love my fancy goldfish. I have a ranchu and a crown pearlscale. Right now they are small, but they'll definitely grow.
These are my favorite ones in all of my tanks. They're so unique. The ranchu swims very funny, and I love it.
These fish are a great choice if you want a cold water tank, but you can find amazing ones for less money too. Mine did not cost the $32 that it says on here. They'll live a long time if you know what you're doing though! Fancy goldfish are very hardy fish. I've never had one die in my 4 years of fish keeping.
You do have to watch out for swim bladder though. These guys get it very easily. Make sure to buy sinking food, or soak their food before feeding it to them. Also you can feed them peas and other vegetables, which will also help to prevent swim bladder.
Overall these are amazing fish and I highly recommend them to anyone with a cold water tank large enough for them.
