All of the dragons that I have ever kept have the same care levels... stable tank with good parameters. They are not all that easy in new tanks. The colors will depend on lighting and can be quite a bit different depending...
I keep all of my dragons at about 250. That is not a lot of light in my tanks. I know that people keep them under less, but 100 seems bit low to me although I have no personal experience with them at this level.
