We just moved our long tentacle plate from a semi smooth rock in the center of our tank to the sand, it has not been all beautiful and flowy like it was when it was up on the rocks we have a Marineland double bright LED which is 1800 lumens. Do you think maybe moving it 4" further away from the light has affected it badly? Water flow is similar to what it was when it was up. We were afraid it was going to move itself (which it had moved about an inch on its rock perch) off the rock and land upsidedown some day so we moved it to the sand which it is supposed to prefer anyway. Don't want to loose our coral can anyone shed some light on this odd behavior?
