No, they do not stay small forever.
Fire belly newts both should get along unless there both females. They will stay away from each other but if you put a female and male together you will get a surprise also i think the blue belly newt will get along with the fire belly cause my friend haves both blue belly and fire belly and they get along just fine!
No, a newt is a salamander and it is an amphibian. Newts live part of their lives on land but need water too, to stay wet, hunt for food and lay their eggs.
No, not usually. Fire belly Toads and Newts are put together all the time, and seem to enjoy each other's company. If they do start to fight, separate them right away.
They could but you risk the turtle eating the newt thinking it was food!
