I have a small nano, with limited space for isolated rocks in which to put fast growing corals. I recently saw a Zoa combo rock for sale that looked pretty cool, so I was thinking that rather than add several small rocks, I might put one larger rock in with several different Zoas on the one rock.
If I just put Zoas on the rock then I guess that wouldn't be an issue, but what if I put a bit of star polyp on there as well? Would the star polyp over-run the Zoas or would they stand their ground?
