Hi there. I have a number of little pieces of rock with coral frags attached to them. I place them in perfect harmony with my rockscape and then a naughty turbo snail knocks them over. I've been tempted to sample these snails as escargot, but that's not a good solution. Is there any way to secure these pieces to the rockwork without actually gluing them to the rock? I really don't want to take out the main rock from the tank if I can help it. Any suggestions? Thanks, <><
