anyone notice that rays tend to lighten and darken with diff substrate? i would asume they do aswell with day and night....i did a search and found a good read on breeding witch was usefull for me as i plan to breed, but no color changeing threads...my ray is eatting loads of food and i first had it on black sand then i took the sand out for a barebottom setup...at first my retic kept the chestnut brown it had with the sand but after a few days it got lighter...now this morning it is a tan/cream color...i never switch the tank just the substraight and my ray is eatting like a champ...the only thing diff. is i have some prazi pro in the system, could that make it change to a lighter color or is it just tring to blend into the bottom...below the bottom of the tank is a black table top so i would think it would have stayed darker...
