This hobby has gave me something to look forward to; something to keep me occupied so I don't go crazy. I have bad hips, so I don't really go out, except for work, and my 1 brightspot in my day is coming home and seeing my fish swimming around when they see me, flapping their little tails back and forth like a dog wagging it's tail.
I keep my tanks in my basement, so my fish are truly excited to see me once or twice a day. I can literally spend hours in the basement watching my little buddies live their life.
I think this hobby has saved me from going off the deep end. My family probably thinks that I'm nuts for spending so much on my fish, but I always retort by saying that I could have a detrimental hobby like drug abuse or what have you.
