just because it has horns, doenst mean its a jackson. lol.
there are sub species of jacksons as well.
what you have is a xantholophus. (aka xanth)
I for example, have a jacksoni jacksoni. which is different coloring.
mine has a green body, with a white stripe and a yellow stripe from head to tail.
the ones with blue eye turrets are also another species.
your jackson will not develop blues (though he may get a bluish tint to the green) or any orange.
