Move it to the top of your tank for the most lighting , Do you add Phyto plankton? Check your Water parameters and make sure all is good. If all these are within' parameters and it is close to your light source ,, it may survive and even thrive.
i had it at the highest point in the tank and thats when it got all shriveled up, but thats still a good 4.5 inches under the water level, should i go even higher than that?
It may be adjusting to a change in lighting. I've had a couple of hitchhiker corals that I've found attached to LR - they were all browned-out at first, but all have recovered. Hope it comes back for you.
