already got a reply:
Hi, yes i have to agree they dont look like they have any blue left in them, i Have had zoas in the past that have looked great and a week after i have fragged then the colours have changed and particularly with the blue. saying that i have kept some of these zoas myself as i thought they were stunning and mine still have the blue in them, so i cant really say why yours have lost their blue? Other than maybe stress from travelling (in which case it will come back) different water parameters, or different lighting but i dont have anything fancy just 3x 54w marine whites and 3x54w antinics.
Im sure you will believe me when i say there is no trick photography or lies with any of my listings, if there had been i will have had loads of bad feedback. I have sold about 12 others of the same frags and had no complaints. However if your unhappy, i am happy to refund you half the price you paid for the frag or next time you order i will throw in a something for free. Or if you prefer you can send them back to me and i will refund your full purchase price.
sounds good to me. not gonna send the zoas back, but might get something more from him and get a freebie.
guess there are some good sellers out there!
