Actually when I go away for a few days a Supermodel takes care of the tank for me and I swear the fish like her much better than me. They always look so happy when she is here.
The Flying saucer thing is a montipora. They all grew from one tiny 1/2" piece. Occasionally one would get in a bad mood and bleach over night which is what happened to that big one.
They grow like weeds all over the place.
That guy is a leopard wrasse. If your head explodes, don't let any pieces of it fall in your tank. Most fish frown on that sort of thing.
