Well, I have worked with V.s.cumingi. I picked them because they were suppose to stay small, under five feet. But, my hatchling male grew to over six in one year, ok, slightly over a year.

But I have bred lacies and croc monitors.

And your right, the biggest problem is size of cage. And its a real problem as most of the time these animals want to reproduce in the winter and here that means indoors. Where space is limited.

I do not recomend Salvators because of their size. They are huge. Which means they take a huge investment.

But for some odd reason, that size is what attracts most people who do not have the resources to support those animals.

If I did not address all of your question, ask some more, thanks FR
