Green birdsnest is about to hit the surface

[gregzz4]

This critter is softball sized and on the top of a rock tower
As of tonight it's close to 1/2" from the surface, and I expect it to hit the surface by the end of the month

Should I;

A - let it grow and see what weird shapes it makes. Maybe it'll start to grow sideways, or thicker. But it will block it's own light

B - crop the top half of the colony, then wait for the bottom half to recover from the extra light

C - crop it close to the rock and watch the base bleach out, then hopefully return to normal

D - bust the whole thing off the rock and wait for the encrusted parts to regrow to it's full potential now that my nutrient levels are more under control

Thanks for any input, and if you're interested, keep your eyes open for a coral sale
