Can you clarify the can't move it requirement? I'd put mine in my frag tank, on a frag rack. I assume the expectation is it doesn't drastically move and not that a snail or whatever can't move it some.
Also I'm curious why that requirement, given starting something on lower light then cranking it up is standard, and if not allowed someone can simulate the same effect with fancy lights.
I added some details last night.
"Acclimation period and final placement choice until March 24th. Photo and placement photo REQUIRED. You cannot move your frag afterward."
So after you've had time to, acclimate, tinker, and adjust then it's time to leave it be and let it grow.
I've looked into not only our previous growout but also a few others from other site contests. It's a part of the husbandry challenge to test your skills with sps in general. Knowing your flow and lighting is critical, that is why I included that caveat. If you choose to leave it on a frag rack, that's fine. I hope that helps.
