Since Pure Hybrids are no longer Pure Elementals, your top earning Hybrids are now Pure Hybrids, except in a few isolated cases. Replace the Hybrids you now have in the Habitats one at a time. Put the Dragons you don't need inside the Dragonarium or sell them as you hatch their replacement. 4 Pure Hybrids in a Big Dark Habitat fills it up faster than 2 Pure Hybrids in a Pure Habitat. :) Especially since your Dark Crystals now work on your Pure Hybrids. :) Surprised you didn't think of that.
