I just saw a fragment of a bubble coral I had lost during the move of my tank. The rest was dead, but somehow this frag made it to the bottom of the tank and survived. What should I do with it as it is not attached to anything?
Attach with frag epoxy, crazy glue, elastics... it's an LPS so I don't know why you wouldn't attach it. It won't want to be sitting in the sand I don't think.
If you wanna keep it from floating around all over on the bottom, then super glue will work to hold it down, if you dont mind if floating and it will survive, then there you go...
