Tank size and current lighting? You may find that alot of your coral will want to be moved at one time or another after initial placement which is perfectly normal. Where you put it now isn't set in stone so be flexible. lol Some corals may want more or less light than is recommended so you will be moving them around, just how it goes. lol I glue my frags to small rock rubble so that they are easily moved as well as have a place to expand onto rather than my large rocks.

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
