I have three Eastern Water Dragons, just over a year old - Megasaur, Gigantor and Skeletor. They have all started to colour up, so safe to say three boys.
I dont mind selling them individually or together, $350 each or $1000 for the three, and you can have the tank, heater, light etc. Can give you a worm colony too, these guys love their worms. You are welcome to come see them if you are interested.

I have sealed the tank in two, see pics, so they have a decent place to soak and swim around in. You can see one asleep at the bottom of the tank. Tank is 91cmx46cmx46xm, not that exciting, old turtle tank with a crack on the back thats been sealed, but it is perfect for these guys. Mesh and glass lid, light is on timer and ceramic heater keeps that big rock at the back toasty.
