Good to hear she's enjoying her food now.

Are the tubes plastic? If they are then it's good that you removed them, they don't usually eat plastic if they chew it so she should be ok.
If you want to add tube type things to the cage then the best & safest are things like cork tubes or tunnels, hyacinth or seagrass tunnels (available from P@H I think, Amazon & other online pet shops), cardboard like kitchen roll tubes or the small logs with holes in are fine for a robo too.

She probably only bit you because you were messing with her cage, they don't like that!
