How do you tell age of fish?

Answer 1

You can tell the age of a fish from the number of growth rings on each of its scales. Each pair of rings represents a year. The dark narrow rings represents winter; the wider, lighter rings represents summer.

Answer 2

Its quite easy to tell the difference between the genders of fish. First, on there underbelly, there is something called haytorice, it either holds a penis, or the fish has a vagina and thus has no haytorice. Men fish generally eat other fish, if they refuse to have sexual intercourse with the fish bowl.

Answer 3

yes because the fish scales tend to look cleaner and newer when the fish is younger. when the fish is older, the scales look gray and dull.

Know this because: I am a very goldfish owner ^-^

Answer 4

Look at the scales - every line indicates a year, like the lines of tree trunk.
