You are doing awesome for 12. My first tank (somewhere around your age I can't remember) was purchased at G. C. Murphy's department store. It had multi colored stones and some swordtails. they all died. I wasn't very good at it. It wasn't until high school that I kept one close to right so you are waaaay ahead of me.
Lookin nice lil' bro. We're proud of ya and cannot wait to see what the future brings for ya in the hobby. BTW, Barb and I started with a ten too. Be careful
Fish tanks..............Hey at least it's not crack!
