Crossbreeding IS possible, and even a natural occurance.
For instance, a. leukranos is a natural hybrid between an a. chrysopterus and an orange skunk.
An a. theilli is believed to be a cross between a pink skunk and an ocellaris.
A blue eyed clarkii is a fish that is bred for its looks by ORA. (I know a hatchery manager for ORA.) It is an a. clarkii, but bred for a specific trait. It can mate and reproduce with an a. clarkii, because they are the same species. But this normally isn't an issue, because most people don't want the full time job that it requires to raise the young.
Most likely, you would have "normal" a. clarkii, but your chances of an occuring blue eyed clarkii would be much higher.
