[APD] Shrimps in Planted Aquarium

[Edison Yap <integrity_ph at yahoo_com>]

Hi,
   
  I have a 300 gal. planted aquarium with Metal Halide as lighting.  I have around 100 pcs. of different kinds of shrimps.  Yamato, bumblebee, Red nose shrimps, and a black shrimp that turns red, once in a while.  
   
  Before, when I purchased these shrimps, they where grazing the plants during the daytime, when my lights are up.  Now, for some reasons, they are now nocturnal.  I never see them during the day time and the only time I see them is at night when I use a flashlight.
   
  What do you guys think has caused these shrimps to be nocturnal? How can I make them come out during the daytime so that I can once again enjoy them?
   
  Thanks for your help!
