Well it will be a BCC but it all depends on the breeding and bloodlines. You could have a Suri with a redder tail than a Peruvian or vice versa. You could have a Guyana with a fire engine monster tail or one with a tail that is a darker purple. Then there are Trinidad BCCs, Brazilians etc... In my personal opinion it comes down to Peruvians vs Surinames but like I said it really depends on the animal.

Also, note that BCCs are harder to take care of than BCIs and Suris/Guyanas can have regurge issues as babies.
