Hi...I am very new to this and have just built myself an outdoor pond and I was wondering how many Goldfish I can Keep, Without over crowding ?

The pond is 4 metres long
3 metres wide
50cm deep at one end and 40cm at the other
 
ok, your pond is about 2800 gallons. the general rule with ponds is 10 gallons per inch of fish. before you buy any fish though, make sure you have some major filtration, as well as a UV sterilizer if you want the water to be clear. to start off, i'd buy 10 KOI, or 20 common goldfish. you could work up from there.

I have installed a uv filter as well as a water pump and have added lots of rocks for them to hide under.

I would love to add some Koi, But unfortunately where I live they're illegal and we don't have a lot of Goldfish varieties either :sad:
 
I think its so dumb that where I live koi are illegal. A few annoying people release these beautiful fish into a pond then no1 can have them
 
i can't wait until the question is phrased "i have 20 koi, how much tank can i put them in?" that will be a silent victory for the fish.

The pond is 9 feet by 12 feet and 15 inches deep, I know that it don't equal 2,800 gallons. Here is an example :

How many gallons does a pond 10 x 15 feet with an average depth of 1.5 feet hold? Make sure all measurement are in feet, then multiply length times width times depth, and multiply that total by 7.5 to get gallons (10 x 15 x 1.5 x 7.5 = 1687.5 gallons). This would be for a pond that was perfectly rectangular with perfectly vertical sides; an actual pond would probably hold considerably less water than the calculated amount. In addition, all pond measurements tend to be rather rough, so we would call this a 1600 gallon pond.
 
sorry for the bad calculations....
