I agree that statement seemed rude... Even if sarcasm or a joke was the point, remember words on a screen do not have an ounce of tone, which in person tone really makes the statement rude/funny :)
Anyways, A crowntail for sure. Because crowntail is the one where you cross it to anything else you get really odd looking shaggy fins that may not be desireable. Color choice, I do not know what you want.
Breed for the breed, not for the money; the words any REAL breeder would understand.
You must know nothing in order to know all, for all is nothing and nothing is for all.
