Hey I bought this frag to test my maxspect razor lights out. I'm trying to find the right height and settings without renting a par meter. It looks like renting may be easier though. Here us a pic of my zoa at midday. It's odd they are reaching for light it seems, yet they close at midday. In the morning however they all open wide and look normal. I've moved them up from the sand bed a few days ago and they are about halfway up the tank now.
