These will be between 2.25 and 3 inches with most of them being between 2.5 inches. These are a beautiful brilliant blue as juveniles and already have most of their coloration by two inches. As they mature the blue will become more shimmering ending in a beautiful intense almost flourescent blue when fully mature. The amount and type of pattern on them can vary significantely.
