okay, I had mines just abit above the middle of the tank under some t5's. Just decided to do some reading on them and found out that they do better in a low light setting.

Not trying to highjack this thread, but what kind of zoa's are those in your profile pic? they look cool.
I notice mines looked like they were fading so I moved them towards the bottom of the tank and they have more color. I think one has two mouths so does that mean they are going to split?
mine seem to shrink in direct light. I have 4x24watt t5ho. rics are about 12 inches under the light (shallow tank). When i put them in the shade they expand a LOT
