Securing Live Rock

[BryanM]

Preface, I don't want to.... There's around 150 pounds of it in the tank, and that's not very manageable if its one piece... Honestly, having 3 glued together probably would suck to try and get out.

but my goby clearly likes to move sand out from the sides adn likely under the rock. I did my best to make sure it was on the bottom, NOT on the sand, initially, but I've moved some pieces around and now I'm getting worried that this dude is going to cause some rocks to fall.

If you believe that there is a concern ideally it would be best to add some epoxy to a few areas that you believe it may be at risk.
In a ideal world once the rock is placed it shouldn’t have to be removed again.
