How can you tell a goldfish's age?

Question

I just got a Black Moor goldfish from the pet store and I know how to tell the gender. But, the website I got the info off of said to wait until the fish is one year old. Can anybody please tell me how to figure out how old my fish is?

Answer 1

Well your fish have to die if you want to determine the age of it. To find out the age, you can count the rings in the otolith or stump.

Here is a story about the world's oldest koi. They used the scale ring counting method to figure out her age. Goldfish are relatives of the carp family as are koi, so it could probably be used. You will need a microscope and forceps though.

Answer 6

Cut it in half and count the rings.

Answer 7

if the goldfish drives slow and frequents the olive garden for the all you can eat salad and breadsticks ,then you know he's old.

Answer 8

There is no reliable way for you to tell a goldfish's age yourself since they vary in growth speed due to diet, housing, stunting etc. If they are less than a couple of inches long I would suspect they are under a year old (or at least under 18 months).

You can get an estimate of the goldfish's age by getting a biologist to study a fish scale. As scales grow, they make rings a lot like tree rings, that you can use to estimate the age. It is pretty complicated and expensive though, and it's best not to do it when the fish is alive because removing scales can leave the fish open to infections.
