Excuse me for stepping in, as monitors are hardly an expertise of mine. But this statement begs the question of me. How does anyone know precisely what these animals NEED, nutritionally speaking? We can't even get scientists to agree on what HUMANS need to be perfectly nutritionally balanced, and we're the most studied creatures on the planet.
How can anyone make such definitive statements of fact about an animal that so little (relatively speaking) is understood about in the first place?
I get that different keepers will form their own opinions on what is "best"...but to take that opinion and turn it into a "factual point" worth making accusatory arguments about is kind of silly, to say the least.
