Keeping fish to me is a challenge. Can I keep them happy? Alive? Thriving? It's also a learning experience. I have learned so much in doing this, in so many different topics, and I enjoy the thrill of learning something new.
To me, it's a hobby that brings me peace and joy. I enjoy doing water changes, tank maintenance, DIY projects... I'm seldom happier than when I'm working on my tanks, or when I'm laying back, watching the fruits of my efforts.
Finally, it's learning about, understanding, and watching nature. I've gotten to explore an amazing ecosystem in learning about Lake Tanganyika. I feel like I have a little piece of the lake, here in my living room. My children love it, and learn from it. And when the science fair projects start, I'm a walking book of ideas!
