Easiest way to resolve that is to put paper towels or newspaper along the outside of your viv for a week or two. :mrgreen:
My beardie did the same thing and I swear her arm was going to fall off from all the waving!! Once I put the paper towels up, she couldn't see her reflection anymore and calmed way down.
I just recently took them down from the front of the tank (still have sides and the back covered) so I can watch her better and I know she can see herself again but she's much calmer now and doesn't spook as easily from her own reflection anymore.
Hope that helps! :wink:
