My BTA likes to travel every few weeks, even stretches on to rocks three inches away. Last time he got under a cap and over a few days applied enough pressure to unglue it from the rock. The cap was fine and I reattached after the BTA moved on.

Now, he is pushing his way on top of some Xenia. Its been 2 days and so far they don't show any sign of injury, but are leaning way over onto a small stony frag. Should I try to separate or let the BTA get his wander lust out of his system? The Xenia have never bothered the stony, but will the BTA sting it?
