They are exactly the same except for the supposed aggression, but I don't think there is even a 100% aggreement that they are less aggressive. O, I guess another difference is that ou can't just breed two eb's to get eb fry. I don't think eb fry will survive as they will have weak gene data. I don't remember how exactly they need to be bred to get eb fry but there are a few people on TFF who do know.
