ok so I have this red digi I got from a MARs swap over a year ago that was light pink....Everyone told me it was bleached out and will probably turn red if the tank conditions are better. it did in my tank for a while, but now its white again? My yellow digi is fine and my other sps has held colors well over a year. Any thoughts on what is wrong? it is kind of cool looking to have white polpys, but I know its not a good sign.
