I haven't read any other replies to your query re: Creole wrasse 
"schooling" at night so here are some observations:

I have also seen the "parading" behavior you mention at Bonaire.  It looks 
to me very much like the parading behavior of yellow tangs here in Hawaii 
(and other species in other locales).  These parades form in the late 
afternoon through twilight as the fish (often hundreds or thousands) move 
from daytime feeding areas to nighttime resting areas.  Spawning is usually 
associated with these parades (at least it is with yellow tangs; I didn't 
observe Creole wrasse spawning at Bonaire).  Dr. William J. Walsh in Hawaii 
described this behavior for Hawaiian yellow tangs and I'm sure there are 
other references for other species.
