nice man he looks great although a little light in color, this could be due to the high temp exposure. i would fix that ASAP, i really wouldnt recomend anything from petco for they are retarded, as is petsmart but if its your only choice then i would get the calcium and multivites with d3, just dont take advice from the people there unless they own jackson chameleon. UVA is the same thing as a heating light, i would run both heat and uvb for twelve hours a day, im not sure how much uvb exposure jacksons need unfortunately theres not a lot of people who do. and if your basking temps are that high then you are overheating him. they need to be no higher than i would say 77 but 75 is the best, also make sure you have multiple basking points, not just one. you want of course cooler areas so he can cool off, its just like when your in the sun, you want shade to cool off, same concept. also one side of your tank should be cooler and moist other side dryer and hot but just make sure he gets dry and moist periods. i recomend u fix those basking temps before you do permanent damage to his skin... this will also set his metabolism right
