I thought i would share this with all of you zoanthid lovers. A few months back i took a couple of frags off of my rasta colony and kept one of the frags of 3 polyps under very high light and flow. (about 3.5" from the surface of the water) Then, the other frag of 1 polyp we put right near the bottom about 10" from the surface of the water and in much lower flow. Over the last 3 months we have noticed a few things. The ones in higher light grew exponentially faster than the ones on the bottom (for obvious reasons). The other thing we noticed was the drastic colour differences between the two. The ones in higher light seemed to have lost almost all of their orange, only keeping a small ring of it, where as the ones in lower light gained more orange. Here is a picture of the 2 frags placed closer together. The frag on the top was the one kept in high light and high flow, and the bottom one was lower light lower flow. I thought this was interesting and figured i would share it with all of you! Thoughts?
