Is my Notopthalmus V. ready to go aquatic?

[Autumncrossing]

Hi everyone,
I have noticed Smaug the largest of my noto efts (2.5-3 inches now!!) venturing into the water dish lately. He has been turning very dark on the top compared to the others and I am just wondering if its time for me to put him in an aquatic set up? He does not look very green to me like the adults should be.. but his tail is distinctively flatter than it once was.
Thanks! - Heidi

You could always setup a tank with shallow water and stock it with plants while gradually increasing the water level and see how it responds to that.
