Hard to tell for me, but they look very similar. Zoas get very different under the flow/lighting conditions.
My tubs blue in my frag tank look very different from my main tank.
Well officially they have not been named yet. BUT the unofficial name is "Blue Shurikens" which personally I don't really like......The zoa from the bottom pic is just a random pic I grabbed off the web. I like "North Star" alot more.....and not just 'caused that is my name.
!
But zoaid said they would prefer to go with the name that the general public is more familiar with. Which in this case would be, "Blue Shurikens"
