So I'm honestly trying to completely get rid of crickets. They die rather quickly and leave such a mess in my tank that I just want to filter them out. Even when I buy 6 at a time because each of my toads eat 3 crickets per feeding, I still find that one or 2 die before my toads get to them.

I thought mealworms would be the next best thing but the second that they hit the water they die or sink.

So is there any type of bug that these guys can eat that won't drown to death?
