go to another light. or try that light in a few days or weeks and hope another school has moved in to take advantage of the food source. A big school of little ones is going to be a big school of little ones until something runs them off or eats them.
I have seen big schools of them behind grand isle. you could see a few bigger ones mixed in but it was too hard to get a bait to them. the little ones kept intercepting the lure.
it was very cool to watch them track the jig in the air.
