Hobby- Hmmm...I have more than I need, knitting, sewing, cross stitch, reading, writing, photography... Here is a shot from one of the most expensive (of mine, anyway. I realize there are more expensive hobbies (rebuilding cars or something like that) but I have sunk plenty of $$$ into these tanks.(and the 20 others we have around here)
I took this shot to show off the tank stand for some of my aquarium club buddies. The kid in front is DD6, about a year and a half ago.
