What's the difference b/t Colombian, Peruvian, Sur

[Mancolt]

What is the difference between Colombian, Peruvian, and Surinam Red Tail Boas?  Do some grow to be larger?  Are some more aggressive, less friendly and tame than others?  Is there any easy way to identify between all three?  Which makes the best pet?  Thanks

Also, what is a good substrate for Boas? Particularly Colombian, Peruvian, and Surinam (unless suitable substrates differ for these three). Is Aspen alright?

Well basically you are talking about one boa B.c.c and when people say Guyana, Sunirname, Peruvian they are talking about localities of that boa.

Now when you say Colombian boa are you talking about a Colombian B.c.i or B.c.c
