A basic question I think. Just picked up a green brain coral. RIght now I have him on a piece of LR. Would he be happier down in the sand or does it really matter one way or the other.
Thanks.
Most brain coral like low-medium light and water flow. They do not need to be placed on the sand bed, but it might be a good idea becaue they need a lot of room to expand. If you want to place the brain coral on the rock, make sure there is plenty of room for them to grow. Good luck =)
