Betta Fish Age?

[BettaGirl_666]

Hello! I got my betta fish, Galaxy, about a month and a half ago. I was wondering if anyone had tips for finding out his age, or from the crappy photos that I attach here. He's a Koi (halfmoon??)

Can we get a couple more pics to try to see how big his body is?

When you buy a betta they are generally several months to a year old. To me that betta looks on the younger side.. maybe 6 months (comparing it to size of heater in the background and his finage). But I’m not a Betta expert

So sorry I took so long responding! I was busy with other things. Here's another picture. (My pictures kept bugging out, so one was all I could do)

He looks pretty young to me. 4-6 months???

Yeah, I kinda guessed that he would be pretty young. To me he seems on the smaller side of bettas. Thank you all for your help!
