Lizardgi
I used to have lizards
Since taking over a 125g reef, the below colony usually looks just like below, with nearly every middle one tightly closed. They usually open up a bit more in the dark, but that's about it. Any ideas?

I did play with their location a bit, moving them to the bottom of the tank, and I didn't see any improvement. In my opinion, they look crowded, but that's based on no experience at all.
I wonder if they're getting too much light? The ones closer to the shade on the ends look happier. Maybe you can move the colony lower in the tank and see what happens.
Alright, so I'd like to try fragging these a bit -everything I read suggests superglue if any need to be re-attached to rubble. Do you use household everyday superglue? It just seems crazy toxic to me, unless I'm missing something here...
