Also, I should point out that you'll need to move dragons around as you build new crystals in order to maximize the number of crystals affecting each dragon. This won't always be possible and you'll need to compare their gold production rates. This will enable you to put the dragon that produces the greatest amount of gold closest to as many crystals as will affect it as possible.

You'll also end up building new habitats to replace old ones in some cases. For example, I originally had 8 large Electric and 8 large Metal habitats each placed in a square with the appropriate crystals placed inside the square. Eventually, I got to the point where I had three Light/Electric hybrid dragons and so I built a large Light habitat and put them in there. Then, I moved one of the Electric habitats and put the Light habitat in its place (and then stored the Electric habitat). I did the same thing with the Metal habitats and a War habitat when I got to the point where I had 3 War/Metal hybrids. This might seem redundant, but the new habitat will pay for itself over time. For example, with the War habitat that replaced the Metal habitat, the difference in gold cap between the two is 110k (Metal stores a maximum of 70k gold, while War stores a maximum of 180k gold). So, every morning (at least, and more frequently if you collect gold only a few times a day) you earn 110k more gold than you would have earned with just a Metal habitat.

I ended up replacing a Sea habitat with a War habitat (occupants: Space dragon, Quake dragon, Leviathan dragon), a Nature habitat with a War habitat (occupants: Redwoods dragon, Juggernaut dragon, Colossal dragon), a Flame habitat with a War habitat (occupants: Odin dragon, Loki dragon, Thor dragon [all from the Viking Island quest]), two Nature habitats with Light habitats (occupants: Albino dragon, Gaia dragon, Tiny dragon, Justice dragon, Promethium dragon, Chimera dragon), and an Electric habitat with a Light habitat (occupants: Photon dragon, Virgo dragon, and Aztec Emperor dragon [from the Aztec Island quest]).
