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.........

Bruce did not grow in 10gal tank. Several hundred gal in fact.
The oldest fish lives in a small 10gal tank and not grown much since years ago. I think it is still alive.

Generally, a 10gal is enough. The problem is how many really survive long enough and grow to the fish maximum potential. In many cases, thru correspondents, fishes seldom grow above 6". Unless one buy a large fish put in a small tank. Even if it does, the fish is never a show grade fish or maintain well. Yes, 10gal is good enough, just for survival.

Changing water is quite a sensitive topic. Most of the time, articles are talking about small change, but none mentioned the toxicity of the incremental seems-like-non-harmful nitrates. It's not harmful indeed. But many fail to state the danger of keeping in high concentration. A small change reduced the poisoning immediately but not arresting the increasing problem. Well, at least in RG, people here do put a stop plug at a certain level of nitrates.

Is 10% enough or more better ? Well, let the test kits and the fishes tell you. Ask the writer of the article you read, not follow blindly. Experience and witness the change in fish will tends to convince a serious keeper.

It voice down to individual keeper. Serious keeper or just a causal display setup to brighten the house.
