Is there any attitude difference between BCC and BCI?

I heard BCC are harder to keep and more agressive than BCI. Does anyone has any experience about these two guys?

Yes. BCC tend to be more sensitive about everything than BCI. BCI are just generally more laid back. Both temperamentally and with regard to husbandry as well. I can recommend a male BCI for a first snake. I would not recommend a BCC as a first snake - or even as a first boa.

There are exceptions to every rule - I have a friend who has a female pure Surinam BCC that is gentle as a kitten and has always been problem free. And I have a BCI myself that is out to see me dead and I wouldn't allow anyone but me or someone very experienced to handle her. But as a general rule, BCC are more sensitive in husbandry and temperament than BCI. :gj:
