How old is my new friend?

[tinyDutch]

Hi there,

I've bought my very first betta two weeks ago. I got him from a garden center/pet shop here in the Netherlands. Betta's are kept with the smaller fish in the shop (like; one betta between the guppy's), isn't ideal but I'm SO happy that I don't see much of those little cups in the Dutch shops!

So everything is alright and he is adjusting veryvery well to his new home.
But.. I'm getting really curious about his age now, could you help me?



Here he is! I think he is quite small, his body is about 2.5 cm (1 in?).
If I forgot some information you need to say something about his age that's not in the picture please tell me.

Usually the bettas bought from stores are generally 1-1.5 years old.
