The most easiest goldfish question and is simple?

Question

When someone says a fancy goldfish can get 8 inches does that include tail. And when you measure a fish do you include tail or not?

Answer 1

everybody uses both (scientists and fishkeepers) but they always indicate whether it includes the tail or not

Answer 2

No, you never include the tail (or any fins) when determining the size of a goldfish. Body length only.

Answer 3

It shouldn't include the tail, and most measurements that do not specify do NOT include the tail.  It should be from the tip of the nose to the end of the caudal penducle (the base of the tail).
