OK, very basic stupid question. I had my lobo glued on a rock, on frag plug w/o stem, low in my aquarium. It's been doing great. It got knocked over into the sand & the frag plug is now on the rock. Is it OK to let my lobo sit in the sand w/o any frag plug if it seems happy? Or would you suggest I glue the lobo back on the frag plug on the rock? Thank you.
