Hello and welcome to FF Gab! Sorry your frog is sick or maybe just lonely. Can't open pic files. Maybe you can try using a web site like Photobucket to upload your pics and then paste the provided code into your post.
Agree with Michael previous comment about not medicating a frog that does not show specific disease symptoms. Does frog looks bloated compared to recent weeks? Any color changes etc.? Please answer these questions here to get a better idea of situation in tank. Also, do the fish show any signs of disease? Thank you!
