Usually when you see a nice clump of zoas, they have small stalks (2-4 mms) and are all bunched together. I have one frag of zoas that has 3-4 heads, and they sit on the edge of a rock that doesn't get all of the direct LED from the two 60 watt LED fixtures. Their stalks are almost an inch long, and they are way stretched out. I know that they could be moved so they don't have to "bend" toward the light. Does the fact that their stalks are SO stretched, compared to other zoas, mean they need more light, so they don't have to "reach" toward the light?
