i saw then in my LFS display tank. they were yellow there too, which is why i got them.
i will post another pic tomorrow to verify. these things were still yellow today.
im not sending them to zoaid, because i dont really think they are as special as some of the zoas ive seen on there. i would not put these up high with (lets say) my tubs blue zoas i have. i just thought these yellows were nice. ya kno?
