The Blues are not any different in care than a normal colored Pacman. We got 3 of them from Samurai and lost one within the first week. Shipping that distance can be very stressful on the frogs. I would suggest you start with one you purchase closer to home & then when you're ready to take the plunge, go for a Blue.
That way, when you get the Blue, you will have hands on experience and will feel more confident. It will also give you the chance to know if a Pacman is the right frog for you.
