I will share my experience, but please take it at that and not advice.
Bought 2 blue star gals from LA (first order from them ever) along with a coral beauty. They were packed well, the two wrasses were struggling, one was gasping at the top of the water in the bag. Carefully acclimated them and into QT they went (a little ten gallon that is up full time). Put a Tupperware container in the qt with some new sand in it. After a few days, starting treating them prazi, metro, kana, focus, and after that cuprion. A total period of 3 1/2 weeks. The wrasses started eating about a 1 1/2 week or so in, prepared foods. Placed in display and they are doing fine. My DT sand bed averages about 1 1/2" but has a few areas that go maybe 3 ish. I am watching them as I type this.
My pods have disappeared from my glass after the wrasses went in. But, I culture pods and phyto just for the heck of it so I just keep adding them to the tank. The wrasses eat all prepared foods and peck at the rocks and the gravel.
The coral beauty was in the same tank undergoing the same treatments. However, never saw it eat, though it didn't get skinny, was shy and definitely acted like it may have something wrong with its mouth and or gills. It died in qt after the fourth week to the day....
This tank will be 4 months old in a few days.
