I wouldn't quite say I treat mine like children, but I definatly take care of them to the best of my ability and respect the fact that they are living beings that have certain needs. I don't keep mine in bowls, or without heaters, all of mine are treated properly and live in real, heated tanks. They are fed the best food possible. When you take a helpless being into your care, it is up to you to provide it with the best life possible.
So no, I don't treat them like children, I treat them like fish.
