You could get a decoration that also is a hiding spot, they make a lot of tank decor like that. If you have one you just have to make sure to lift it up and disrupt the gravel underneath once a month and make sure the inside isn't getting nasty. You could also have some more plants (silk ones preferably).
One thing I forgot to mention with the heater. Most are sold like this but every do often you get the oddball, make sure it's one you set to a certain temp so it turns off at the desired temp. If you tank is getting too warm during the day (say above 84 degrees) you may also wish to have a fan nearby just kinda giving it some air. But it's still better warmer than colder.
