To the original starter of this thread, i was on the hunt for a truly satisfying yellow zoa for a long time. Yellow being my favorite color, i looked everywhere! i'm not talking about a muted yellow, or a mid yellow, but a true yellow, if you google up a pic of a "yellow clown goby", that's the type of yellow i was looking for. I started off with scrambled eggs, and they were nice, but not even close. I got some Blondies and rainbow infusions, then i got some fruit loop zoas, cornbred mandarin orange zoas, king midas zoas, super siayan, dragon eye zoa, sponge bob zoa, eagle eye zoa, etc...never found one that i felt like was truly yellow. I know it exists, because i traded a guy once, and when i explained i wanted a yellow zoa, he said that he had one polyp of a zoa he didn't know the name, but it was really yellow. i got it and it was a beautiful yellow, but it never grew much, just got to two or three polyps, this was a while ago, so my memory on it isn't 100%) Anyhow, good luck in your search, if you do find something, please post up a pic, and the name, and where you got it from! I had a tank crash, and all my zoas died, so i'm starting over from scratch...
(one additional thing, i'm talking about looking yellow under regular lighting, not with just the blues on)
