Update guys. i have change some decor in his enclosure but begging to think my UVB is wrong as the last couple of days he’s been glass surfing and rubbing on the glass non stop to the point his nose is changing colour. the UVB i’ve got is the arcadia 12% T5 39W and i think it’s too long. it covers the whole viv so today i’m setting up a 24W so that he can have a more shaded area to see if that helps. basking temp is 41 ish surface 39 and cold end is between 26-29. diet hasn’t changed. anything else i can do as it’s been constant and i’m worried he’s going to hurt himself
