Hi everyone I am a new sulcata owner and purchased him/her around a month ago. Unfortunately I’m afraid I am doing something very wrong because their skin is much much darker than when I got them I am very worried and would appreciate any information! I have him in a 20 gallon tank with a heat lamp and uvb bulb I have on about 10 hours of the day, keep his humidity no less than70% and am feeding him spring mix. If you have any suggestions please let me know!
