Hamsters, Turtles, or Fish?

I used to have a pet hamster but one had a disease. Then I got another one and it died because of old age. (I had no idea it was old, the 1st one had green poop.) I have all the supplies for a hamster, cage, food, and all that other stuff. I want to convince my parents to let me get another hamster. When I get the hamster, I want them to have babies! I used to have a turtle but it died in a cold fish tank. (long story) When I had that turtle I bought another one to keep it company. The 2nd turtle kept fighting my 1st one, so we set it free. (They were both boys.) I used to have fish but they all died 1 by 1 some mysterious reason...well anyways if I get fish I want them to mate too and have fish babies!!! Oh yeah, and if I turtles I want them to have turtle babies too! I have all the supplies for these animals, fish, turtle, and hamster!!! Now which pet would be better? I have toys for the hamster, and lights for the turtle, and a huge tank for the fish. I cannot decide, and then I have to convince my parents and somehow make which ever pet I get, mate. Which path should I follow?
