thanks guys....
@Taylor, the OS tang is a MAC certified one I bought from MCF as a baby (all yellow), the orange shoulder now there and from tme to time you can see the line croasses vertically through the middle of his body that will eventually appear. Also, the shape of the tail is now more of a sickle (versus a triangle), which is really a cool transformation.
@EyeReef - thanks, I have some parts that have grown own faster than others, it's amazing how it transforms as it grows, I'm really enjoying it over the past year. I finally started to buy some higher end frags as well, I got a nice Strawberry Shortcake from MCF as well as a few others from their show tank.
