Maybe I am just worrying too much but I find that my frogs sometimes frantically claw at the side or bottom of the tank as if they are trying to get out. Is this a natural thing that they do or are they unhappy with something?

I have 2 in a 5 gallon tank. I am trying to decide if maybe they need some more friends? Or maybe they need more hiding places or plants? I have a small little house, decoration, and a fake plant.

I really want them to feel comfortable and I am not sure what I should be doing. If you have any tips, please let me know.
Thanks!!!
