J.B. since you are relatively young, allow me to extend your passion beyond this typical hobby and help you focus on what could be a life choice.
the thing about this hobby I find myself actually passionate is the idea that we are all trying to create an ecosystem that is not just aesthetically pleasing, but is also healthy for the fish and plants, and as self sustaining as possible. I find my appreciation for Ecology, healthy food, healthy environmental air and water, and desire to help with green causes around me growing.
If I were a younger man, I might have channeled that passion into my vocation. decades ago when I was your age, a green vocation was not lucrative at all, but now such vocations are more lucrative than ever. the markets demand healthier food processing, building are made greener with water and heat reprocessing, water and air filtration, water reclamation, green mineral mining, new technologies in organic farming, recycling, low emissions power generation, green marketing, entertainment, economics, education and publishing, the possibilities are endless.
Such a vocation will not only be lucrative and fulfilling, but can help make this planted fish tank called Earth, that we all live in, a better place for our children to inherit. it's a fortunate person who finds his "calling" in life, and perhaps your enthusiasm for planted tanks can be extended to your educational and vocational pursuits. just some food for thought
