^ Poor goldfish! You guys didn't know any better though. I kind of blame movies for giving kids the idea that goldfish are low-maintenance and don't need water conditioner (e.g. "My Girl").
When my younger sister was about 13 she bought these turtles from some street vendor. I knew she didn't know a thing about raising a pet so I questioned her decision but her response was along the lines of "but i want it i want it i want it!!" My parents seemed to be in denial that they were HER turtles, not mine, and decided it was BOTH of our turtles, and had me changing their water all the time. >.< My sister NEVER changed their water. I was so mad because I wanted to concentrate on studying for my SAT's at the time, not mind pets. After I left for college they dumped the turtles in a lake.
Moral of the stories? Parents should be a lot more careful about allowing their kids to have pets.
