My little guy was purchased from FL Chams. They said he was 4.5 months old. for the first month I had him, he wast either solid apple-green or twig-brown. One time he turned a solid pepto-pink and that was pretty cool. His patterning and color spectrum seemed to show up at about 6 months of age and increase in intensity up to the current time at 7.5 months of age. I have been told he will continue to mature up till about a year of age and he already is looking spectacular with his strips and spots, colors of bright turquoise, yellow, orange, black and dusty blue. Oh and his huge casque.
