Lol, I just remember my beginner's fiasko with two Night dragons in a row when I wanted innocently to breed a Coral. Not only do these things occupy your den, nest and evolution temple for 23 hours each before you can trade them. The habitat holds ONE dragon and cost 500k coins - this was a crazy amount for me back then. I learned the hard way that if you want to avoid Nights, but want purple/blue offspring, breed with a Night against Water or Magic. They will not occur from splitting black.
