I have the Chinese boxes but notice all the sps around the bonsai it is at the right level for sps to grow as this is not the first sps I have had. I have a red planet next to it that is growing fast. IT also has room before hitting the back wall.
Had mine in the back also and had a deep purple. I recently rearanged the top half of my tank to accomodate lots of sticks, so its in the top middle towards the back, but getting much more light. The new growth is a bright blue. I have noticed that at least mine like a bit of flow. In lower flow, the polyps are pretty retracted. At first, I thought I was bleaching it with the new placement, but for the first time, I'm getting some upward growth, so must be happy. I've noticed that those sticks do like a LOT of flow. I thought I had high flow, but I want more. Only problem is I risk ripping all my zoas from the rocks, LOL! I'm running an MP10 at about 50% on my tiny tank, and I'm looking to upgrade my return pump (which is already upgraded to bigger than stock, LOL!) I've considered adding another powerhead for what I now call "stick row"

I'll post pics this weekend:wave:
