Feeding? : )

[bobz]

My gecko still hasnt eaten yet and it has been almost 2 weeks now : (. He is a Golden Gecko but lives in a very big tank(100+gallons). Is it possible that maybe he cant find his crickets and mealworms? I usually put in 3 or 4, should i be putting in more? Also i just bought him on of those exo terra waterfalls and i put the calcium in that to maybe at least try to get his calcium up. Does anyone have any advice?
