Coral spliting and moving

I have Zenia's that are splitting and moving and a giant cult coral
that seems to be splitting in two. what can I do to help them with
their mission to multiply? The cult is on a very small rock in the sand
so there is no place for it to go. and the Zenia is moving to other
rocks in area.

Xenias are notorious for multiplying in aquaria...
This is very fast growing coral and spreads quickly.
It tends to climb up on the rockwork, so if you add
a rock on top of it, it will start growing on it...
I have not have colt coral, but all corals are relatively easy
to multiply asexually and you just sit, relax and watch them grow :-)
