I agree that your male looks like a Nosy be. The photo of the supposed sire is an Ambilobe. Either they mixed up offspring or, and I hope this is not the case, your male my be a crossbreed. It is possible they accidentally matched the ambilobe sire with a nosy be female since the females often are hard to distinguish. I would call the breeder and ask if he has ever raised one of his offspring from that pair to adulthood to see how they look. Good breeders 'holdback' offspring from time to time so they can be sure of thier bloodlines. Did you get him from a reputable breeder? I hope your guy is a pure Nosy be. If it turns our otherwise, he sure will make a great pet, he is awesome.
