oh good to know...and really? so they grow by just the light?
Matter of fact statements like this are very misleading. To think they feed by light alone is silly. Many people think because they never feed their zoas directly then that must mean they are only feeding by light, completely ignoring the chance that they are pulling food out of the water as it floats on by.Looks like radioactive dragon eyes to me. You don't need to feed Zoas does nothing for them as they are photosynthesis.
