I believe taiwans need more floor place.... you should flip it. Like, horizontal rather than verticle. I do not remember if you posted demensions to that cage, but I think a good size for an adult is 4ft long, by 2ft wide, by 2ft deep. This way you have enough floor space and also you can add some huge branches to let them chill at the top.
I mean, do you want to see your taiwan curled up all the time? From my experience they are semi-arboreol, but mainly terrestrial. I love to see mine stretched out, they are so beautiful. As a hatchling, mine would be more at the top of the cage when offered things to climb on, but now as an adult she is much more terrestrial. That is just my opinion. Post some pics of your taiwan.
