Check out www.mazuri.com and the crocodillian diet. Would this possibly work on water monitors. The ingredients are shown and it looks pretty good to me. Cheap too, much less expensive than other food items, 40 lbs for 50 dollars. I think it could be fed to them, but not exclusively. Rats and other whole foods would have to be offered also. Give me your opinions. I will post some pictures of my 4 month old sumatran. He is around 20 inches as of now and is growing fast. Anyone else feel free to post pics of their monitors, it will get the forum going again. Thanks
