Does anyone have a recommendation for setting the corals in place? I have one area of rock that will not hold corals with the bonding agent my LFS gave me. I lost one grass looking coral because it would not stay and kept getting knocked down my the hermit crad or the giant snail. Now I have another in that area and the green&white bonding stick stuff seems to only work on that side for a few short days then it stops bonding and the coral gets knocked down. I don't want to lose another coral due to stress. Any suggestions would be wonderful. Thank you.
