Those of you that are spending well over $100-$500.... is that because you have many animals? Are you buying all of your feeders or breeding? It just seems like a ton of money to be spending on pet food!
Crickets are more fun for the gecko to chase after. Some geckos are lazier than others and won't want to chase crickets after they've been spoiled with worms, but otherwise it's entertaining to watch and better for the gecko to get a little exercise.
