why is that my super hypos are one day really brioght or a few days, then get there pores alil darker and and skin . there skins first yellow bright. after a day or two it gets alil darker yellow with alil rbrown. this is not because of shedding which they do every 3-4 weeks i think. but they are healthy i know this. because they eat every day to two days. and there tails are large! as the geckos tummies. is there any reason for this. btw some times they look like an orange sparky look on the sides is there along with the brown coloring.
