I'm on a run, so be short.
tank is too small, humidity is too low, 3 sides of the tank are not covered + very high traffic. that is why they are so stressed out. weird though that you're saying you have them for 5 years only now they started to behave like that. in these conditions they should have started doing so a very long time ago. have they always been so brown?
would you please take some more clear pic of a frogs (both).
