My wife and I are both artists so he's got to have some knack for drawing and aesthetics. He's 9 now, so it's a good bit of responsibility, but all of my kids work around the house so the labor shouldn't be something I have to fight him over. I've had him hang drywall with me already.
I didn't get my first tank until high school when I had my own money. My parents had one when I was small and told me that the red tailed shark we had, was in fact a real shark, and it was mine. Something stuck after that. Possibly why I've always wanted the big bad fish. I'm 35 now so that's about 20 years of tanks. There is where all my money went.
