Recently I obtained four OG jawbreakers of various sizes. I have them on the sand in an area I consider to be low flow. Two of them are on small rocks glued to frag plugs. They appear healthy. At night it’s become clear that the ones on plugs are migrating off of their rocks and onto the plugs. It’s a bit strange though: the half of the foot that has moved to the plug is well attached, but the part that was on the rock has lifted off. At night when the sort of pucker up, this is very obvious to the point that I’m worried that they will get caught in the minimal flow and peel off of the plug/rock. How concerned should I be? I guess this is why people have mushroom cages…
