mind posting pictures of the frog? im not positive on whats an "ideal" temp but i keep mine no where near 85. i dont even use a light on mine at all. my house temperature is perfect for them. usually about 76 during the day and a little lower at night. i have heard a lot of bad things about the fake grass mat...i wouldnt use anything but papertowels for now. since they are new i would also try to leave them alone a bit. maybe cover up 3 sides of your tank with something (background, poster board, newspaper, etc) so they wont stress out as easy. a 10 gallon wont work for them forever. but i guess it will do for now since its just 1. has he been eating? and pooping? its best to get a fecal check done. depending on who you got your frogs from they easily come with worms or parasites. Dr. Frye can do a fecal check for you and also send medicine if needed.
The cost is $18 per group of frogs housed together. Collect 3-5 feces from each group of frogs and put them in a small air-tight container with a small amount of moist paper towel to keep them from drying out. Label each tank’s sample and send them ASAP to 517 West Main St, Milan MI 48160. Try to aim for a Tuesday, Thursday, or Friday delivery. We are closed Wednesdays and Sundays, and the hospital closes on Saturdays before mail arrives. Next day delivery is ideal, but 2-day will work. You can include a check, call my hospital to pre-pay via credit card at 734-439-2273, or send me funds through Pay-Pal at email@example.com .
im not sure about what the spots and ring are. the mark on his nose could be from him hitting the glass because the enclosure is small. a picture would help greatly if you can do so while he is sleeping so he is not disturbed. and from what im reading you have a mat on the sides of his tank?? if thats correct, i think mine like the glass better than anything. i would put something on the outside not the inside. so he can stick to his glass.
also there is a form on "trouble in the enclosure" might be easier for people to go off of reading that if you dont mind filling one out.
Trouble in the enclosure or a frog is sick ?
It is great that one seeks advice ! After all, that's why we are here !!!
There actually may be nothing wrong , or conversely, a change in behavior warrants keeping a close eye on your froggy friend !

Edit: was your frog field collected? you might want to email dr frye about your problem, your frog could have a skin infection. ive seen others with black spots and dr frye can mail you medicine for it. he has saved many peoples frogs just by simple emails. i suggest a fecal check asap and emailing him.
