I am not offended I totally get where you are coming from, I have seen what happens to reptiles that are not properly taken care of.
I am going to set up for some nile monitors, because I love nile monitors also and wanted a pair forever, and finally am in a position to accommodate a pair. In the time it takes for me to raise them I'm sure the griseus will be possible to achieve and ill have experience with building and feeding niles.
