RE: Mr Sticky
I don't know this product but I wouldn't recommend any adhesive with a soft coral. The attached tissue dies, rots, and the rest of it just floats off. There are some exceptions with a few other softies, but not zenia. For xenia, I recommend bridal veil and a rubber band on a piece of rubble. The other thing I do is put some in a small plastic bowl full of rubble in an area with low flow and just let it attach on its own. After a few days its will be attached to the rubble and you can then glue the rubble where ever you want in the tank.
