Hello:
It depends on what kind of habitat you want to have. I prefer Tropical Water Dragons myself. A nice big healthy male Chinese Water Dragon is pretty hard to beat. I'm raising one now I've named "Bandit" because of the dark streaks that come out from behind his eyes. He is about 14" and is already thickening in the jowels and showing some red on his shoulders. His tail bands are also quite bold. Best of all, his rotral area is perfect.
I have to admit though that "Frillies" are cool for desert inhabitants.
Have a Great Day!!!
