THANKs .. Amazing People Here .. :-)

I upload photos :
Actually I have two BPs from Same Clutch , Same shop , same rack system , same size .. in same positions ..
As you can see in the photos the bigger enclosure is for this one not eat and the other one for the one who always eat with less weekly basis .. !
WHY and What I can do ..
One guy advise me to put some garlic on the prey ( the Fish food type come with garlic ingredients ) .. is that true .. He said BP love garlic and make them active to eat ..
Sorry for my broken English .. But Hopefully you are understand me :-) THANKS
