Sorta juimped in here without reading the whole thread, eh?PavoDive:3. ??? Not native to the caribbean, IMHO
4. Blue Angelfish (Note the yellow border on tail. Queen angelfishes don't have it, but a blue ring crown)
6. Tomtates?? Not sure, but the yellow stripe makes them look like. Their dark back confuses me a little
#3 is a Yellowbar angel (recent import)
#4 is far too colorful to be true blue... it's a Townsend hybrid.
#6 has already been properly ID'd as a Cottonwick
