So a Gray Tree Froglet I have seems to have a redish-black spot right on his snout, and while I'm not sure it's nose rub, I saw him with his nose against the side of tank. I've never had a frog get nose rub before let alone a froglet, so I'm not sure what actions I should take. Should I apply anything to it? I've heard Neosporin minus painkiller is used in certain situations like these. I'm including a picture as well if anyone would like to confirm that it is nose rub as well.
