I have been using real plants in my tortoise enclosures for months now. My ornate, Mildred, tears them up and kills them almost immediatly. My Redfoot seems to not care one way or another. I have noticed I am being plagued by gnats and other little bugs...is it bad to switch to fake plants? I am thinking the upkeep would be MUCH easier but wanted to ask before redoing all my cages.
