Ditto to what Zippy said, enjoy the high school years and get involved.
I would also talk to some of the teachers at the school and see if one of them would be interested in maybe moderating an aquarium club at the school. Since you already have tanks going you would be able to pass along a good bit of information to others, and who doesn't like talking about their tanks. You never know who has the same interest in fishkeeping as you do.
