i rescued one about 6 months ago...pretty much fully aquatic..i've never seen her come out on her dock to bask...previous owner purchased as a baby and kept it in an unheated tank...that was the only reason it came out of the water to bask...i have basking light on timer to come on for a few hours every morning...also have a uvb light that comes on at night time...easy to feed..but pretty messy like most turtles are...just happy that she won't grow as big as red ear sliders..i think max size is 10"...currently in a 90g tank with 2 yellow labs which she leaves alone...eats anything and everything...
