How many goldfish you can put in your aquarium is a question that most aquarium hobbyist have when setting up their goldfish tank. The first thing you want to do is make sure you never overcrowd your aquarium. The thing that most people tend to do is place to may goldfish in their aquarium. By overcrowding your goldfish tank can lead to tons of problems. Overcrowding your aquarium can kill your goldfish. The more goldfish in your tank causes more fish waste that your filter may not be able to handle. Sure some people can add extra filtration to accommodate the amount of fish in the tank but you really shouldn’t add to many fish. When adding too many fish it also leads to problems with goldfish health, goldfish diseases and sickness. When the tank is overcrowded goldfish diseases do occur and they spread very quickly due to the amount of fish there are. Therefore the reproduction rate of parasites drastically increase as there are more parasites breeding and infecting other goldfish. Also overcrowding stunts the growth of goldfish decreasing how big goldfish grow and how long do goldfish live.
The answer to this very common question is that you should only put one inch of fish per one gallon of water. Now this is a general measurement that people should aim for but this does not always apply to fish. When you have larger fish in your aquarium they are gonna need more water. A good example is say you have a 10 inch goldfish and you place it in a 10 gallon aquarium. It’s common sense really when it comes to larger fish. That 10 inch goldfish is not the same size as ten one inch goldfish. Bigger fish need more water to live in, do to their bigger bodies and bigger waste loads. I would suggest for goldfish of bigger size, maybe one inch for say every two or even three gallons of water would be good. Remember the more water your goldfish have to live in the better they’ll be. The water chemistry will be good and the filtration will help ensure your goldfish stay healthy and live long healthy lives. 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.

Hamzah,
How big is your first goldfish really depends on whether or not you can put more into your 2.5 gallon aquarium. If for instance your current goldfish is say one inch long you could technically put one more 1 inch fish. Just remember when placing more fish in an aquarium you will have to keep up with regular maintenance with cleaning and water changes. Just make sure you do regular water tests to make sure water chemistry is good.
If your goldfish you have in your tank is more then 1 inch long I wouldn’t put anymore fish in the tank. If you do can cause problems with water quality and also your fish can become stressed and possibly develop goldfish diseases with unsanitary water due to build up of fish waste.
Best thing to do if your looking at increasing the number of goldfish you have is look into buying a bigger fish tank or aquarium. Then you would be able to increase the number of fish you have.
If there is anything else I can help you with please feel free to ask. Hope this helps you.

I have 13 goldfishes. Seven of them are put in a mediam tank , another six are put in a Large tank ,only one is put in the small tank as it has abdominal disease( always swims not well and often swim sideways )
What types of goldfish do you have?
It’s good that you seperate the goldfish between tanks to cut down on the waste load being created in which the filter would not be able to handle and possibly cause goldfish diseases to occur.
You must have fancy goldfish like fantails, blackmoors or orandas as swim bladder disease most often affect fat bellied goldfish. You should trey feeding the one in the small tank some crushed up peas this is known to sometimes help.
You must like the goldfish hobby quite a bit to have several tanks.
What size aquariums do you have? Try feeding your goldfish some peas and see if that helps.
Thanks for visiting my goldfish blog, if you ever need anymore goldfish help, please ask.
