My only real concern is that if you are not able to make it to the petstore every few weeks you are really not going to be in a position to care for newts. They require a lot more then just a tank, and even bloodworms are expensive. I just feel that you may have real trouble finding a healthy newt in the petshops, and it will take you some time do get one otherwise from a reputable source. Furthermore, live foods are really importent for newts as well, such as earthworms, blackworms, and waxworms.
Andrew is right too, orientalis(chinse "fire belly"(your not going to find Japanese speices by the way) needs temps under 70 and temps of 80 will kill them.
