She won't be coming to any harm so i wouldn't worry about it. She's just following the vibartions she feels as you walk past. Do you keep her up high or on the floor?
I have a computer table which shes on atm. She also leaps out at you if you go near the crickets lols and sits next to the side of the tank where they are lols.
She was in her hide again earlier which is good lols.
