Two of my four toads have grown considerably bigger than the other 2. I don't know if they are like tree frogs, and the females tend to be larger and eat more, but they are all eating well right now, so I'm not concerned about the size difference.

The two bigger ones could easily take down 1/4 inch crickets right now, the smaller two still need fruit flies. Would I have to worry about the smaller ones attempting to chomp down a 1/4 inch cricket? Should I start feeding them separately?
