how many gold fish can my new aquarium hold?

I am setting a new aquarium for gold fish. It's 200cm x 50cm x 50cm. The gold fish i am going to have are about 5-7 months old. I also will have an aerator and i'm planning to do partial water change weekly. How many of those fish can i put in there to the maximum?

1. 10 but all of them may survive completely with others
2. 6
3. Thats nearly a 7 foot tank! Must be about 130 litres? An aerator is not good enough of its own ESPECIALLY for goldfish Get them a really good filter. Interpet do great internal ones but you are probably look around £30 for one Bottom line No filter, no goldfish Good filter - 5 small goldfish? They get really really big though so you could probably only keep the same ones for about a year, maybe a year and a half
4. 10
5. If your measurements are correct that's a 7 ft long tank by 1.5 ft high and wide! You can comfortably house about 10 larger goldfish in there now but you will need a filter. Aeration isn't enough to keep a goldfish tank clean. Depending on what type of goldfish you get would make numbers different. The long bodied comet types grow much larger at a faster rate than if you are planning to put in the fancy round bodied types such as orandas.
6. If your measurements are correct you have a 132 us gallon tank on your hand, 500 litres you could put up to 10 goldfish in there, but no more then that Hope that helps Good luck EB
