Best Fish for Beginners (Kids)

I have to disagree with you.  My cousin could keep her little guppies, I don't remember exactly what the fish were, but like eight of them in a fishbowl without a filter and wouldn't clean the tank until it was green.  She had her fish for years.  I have a big tank with clean water, the correct ph, filters, and the whole bit and the fish dies in a couple days or weeks.  The only time they ever lived longer was when my mom took care of them.  But I do think some fish are easier than others.
