I'd put fairy rock on the sand isolated from the rest of the rock work.

The digi looks happy, and it will probably grow as is.

The pocilla was jammed into the sand bed before, it should be fairly happy in the rocks.

The blue ridge coral is the brown lumpy thing. When it's happy you will get a little polyp that makes it look fuzzy. Keep that away from any large pieces of rock, it will encrust over anything that surrounds it.

The neon hydnophora, that will encrust as well as grow up. It gets fuzzy as well. It can, and will, give you a stout looking branchy coral.

The scuba steve is perfect where it's at. It will continue to grow until you have a large ball of it growing. Moderate to slow flow over that one.

Now that you've got some sps in that tank, might want to check your calcium levels to ensure you have enough. You should still be able to keep on top of the coral demand by performing water changes regularly.
