it doesnt have to look exactly like the pics in the guide. and its okay im a noob too. the three that i have, i have obtained in the past....month and a half or so. got my first one (a granite) and, as many people, was addicted immediatly.
personally, i would call her a granite. The only way (that i know of) to be sure that she is a genetic granite would be to breed her with a normal and see if you get granite babies.
but whether she's a granite or not. shes still awesome!
