Actually he just started eating last night so I'm thinking that force feeding is not going to be necessary (if he continues eating on his own). And you would be surprised how easy the tank is to clean. The plants that are in there are all in pots so I can take them out to clean and so he can't destroy the roots. It's very easy and effective. And the UTH is on the side of the tank not the bottom so he can still burrow to cool off. And he will go to the other side of the tank if he needs to. he usually is on the warm side in the morning and will move between the two sides throughout the day.
And yes, he can get into the water dish. Generally It's pushed into the substrate more usually. But he seems to have no problems getting in and out of it. It's only a temporary dish until he gets bigger. Because he will be outgrowing it soon I'm sure.
