housing savannahs

[littledelgado]

Hi - I'm asking this question for a friend - he has one savannah monitor in a very large enclosure, and wants to buy another one. He has found one in a local pet store that is the same size as his (approximately).

Due to the difficulty in sexing monitors, is it advisable that he has two savannahs in the same enclosure, especially not knowing whether they are 1.1, 2.0, or 0.2? What potential dangers are there in having any combination of them together?

Also, does anybody know of a way to sex them (I read somewhere to probe them, but of course it didn't give any indication as to what to look for - or a scale count like in snakes).

Any help would be most appreciated.

Thanks

Damon
