I just noticed the link to your picture.
If you go with a bigger tank, you need lots and lots of clutter so they don't feel so exposed.
In addition to the two hides, you might want to cover the screen top...maintaining humidity with the screen is tough at best.
Larger water bowl might help too.
Get a digital hygrometer/thermometer too.
I also found that the UTH's run really, really hot.
You might want to get a dimmer switch or better yet, a thermostat.
