I cant post pics but I believe He's nose rubbing he's in a 20gallon tank for now and I am getting him a 18x18x24 next month. it isnt really red though its a white color like its trying to heal, or i am thinking he didnt brush up against whatever it was very hard. i think its the silk plants i ordered from petco or the lid he is brushing up on. I was thinking of putting neosporin without the painmeds in it to move it a long.I see a lot of the other frogs with te rub and there rubs are really red, my frogs is white looking, it started of looking like to scratches one on each side of his face then one in the middle in between his nostrils.his nostrils are ok though.
