I do my GT fishing at night simply because from the shore its their prime feeding times. I've also caught other fish using poppers at nite. Its not a very visual thing and doesnt need to. Your popper does most of the work already pushing water, so really its more so the action of the popper than the visual aspect of the lure. There's nothing really different than fishing during the day. Unless you are fishing the reefs from a boat then you gotta be more concern about the reef than the fish.
