This is one of the top questions that aquarium hobbyist have getting into the goldfish and aquarium hobby. Everyone wants to know how many fish they can put in their aquarium when setting up their tank or even pond in fact. The biggest thing that people don't want to do is overcrowd your aquarium by adding too many fish. What happens when you overcrowd a fish tank, it causes too much stress on the fish itself and also the filter as well. Not only does it cause these problems but will also end up creating poor water quality as a result of all the waste being created by your goldfish. With poor water quality and ammonia spiking it will end up causing your goldfish to get sick with diseases and possibly even death. In such crowded conditions it wouldn't take long for goldfish diseases like Ich to quickly take over a tank. The reproduction rate of parasites would drastically increase and start infecting other goldfish.

Generally speaking people should only put one inch of fish per gallon of water. Now this is a general measurement but doesn't always apply to all fish really. When people have larger goldfish you are definitely going to need more water for that size fish. A good example of that is say you have a 10 inch goldfish and you place it in a 10 gallon aquarium it would look quite ridiculous. You need to give larger fish more room and water to live in to be healthy. The 10 inch goldfish is not the same as ten one inch goldfish. So the general rule of thumb that you hear does not really apply to all fish. The bigger the goldfish they will need a bigger environment as a result of not only their body size and length but how much waste they will produce as well. For bigger goldfish you need to allow more water per inch of fish. I would say go about 1 inch per 3 gallons or if not more. The more water the better and your fish will love you for it. By allowing more water per inch your water chemistry will stay good resulting in less chances of stress on fish causing goldfish diseases and the healthier they'll be.

With proper filtration and maintenance on water quality will help ensure your goldfish stay healthy. It is in your best interest to follow this simple guideline and adjust accordingly to the size of goldfish you have to be sure not to overcrowd your tank. So how many goldfish to put in your tank really all depends on you and how big your aquarium is able to hold using this simple rule.
