Tank Size......east Vs West (generally ) Options

[stooeygee]

Since ive kept goldfish ive been learning from two sites ( one mainly from the western hemisphere and the other from the eastern hemisphere).

In the west acceptable voluume to keep goldfish is 10 us gallons or 38 litres

So why in the east acceptable levels are 26-27 gallons or around the 100 ltr mark?

I want tensure my fish are given the OPTIMUM water conditions so would love your advice on growth etc.........

Common tank sizes here comes in feet; 2ft tank,3ft tank or 4ft tank is the most common.Only mad people like me have a 7ft tank.

The volumes of 2,3 and 4 feet tanks are approx. 100l,200l to 400l respectively, depending on the width and height.

There are people in the east who keeps goldfish in 50l tank as well - they are the ones that tell you that goldfish are hard to keep,succumb to diseases easily and their maximum size is 3 inches.It is very difficult to convince hobbyist here in the east to keep 80 to 100l per fish, believe me.
