are you looking at with the lights off? I have a frogspawn and its tentacles darken up quite a bit when retracted but when they are out they are fine. You havent noticed and browning of them during the day have you? like a jelly or slimy brown covering over them? i not and they look fine with the lights on I wouldnt worry about it. I guess with that long tent sucked up into a small space, it wont be as light as with it fully extended. thats my opinion but lets see what the pros have say
I;m so deep that if water tried to listen then the rivers would sink...knowledge is power, get ya weight up!
