The first one should i put it on the rocks instead of sand? and can i cover the uncoral filled side?

The first one is some very nice looking zoas, but I can't identify the color morph. The second appear to be some nice palys. Very good. And yes, you can cover the frag plug with sand if you want, but you can also leave it alone and let the polyps spread.
