well yellows dont really spend alot of time in water, not nearly compared to green, my setup i have is fairly simple, ill get pictures tomorrow, its a 30 gal, i have a huge water bowl so she could fit in if she wants, a hide on the warm side, and cypress mulch bedding. greens spend alot of time in the water because its easier for the water to hold the body weight then themselves. so if you have a green id maybe look at doing some type of water/land setup.
