Should crickets be dead for frog?

Sherrys right, a frogs eye sight is akin to T-Rex's in Jurassic Park (not entirely that far apart on the evolution scale), at least i know that rings tru as far as American toads + FBTs are concerned. Ive seen pet stores sell bottled dead mealworm feed for frogs + its a complete waste of time + money. Frogs wont bother with still prey unless you bought a vibrating food dish to put dead food in

thats also why frogs tend to dive at eachother during feeding time, theyr just darting at the largest moving object nearest to them
