Mealworms simply because I realized yesterday that crickets can hide under reptile carpet.
Also, though crickets breed much faster, I like mealworms simply because it's easier to handle them and care for them and whatnot. I like cricket chirps, but I don't like the smell of crickets.
I'm wondering if it's simply just that there's such a minute amount in Calcium+D3 powder that the gecko would have to eat half the container for it to actually develop health problems.
I'm thinking the calcium would start to have negative impacts on the gecko before the D3 can actually do...
