EB acaras and EB rams are fertile - you get 100% EB fry if both parents are EB. They are fairly robust and look/eat/grow/breed like their wild type counter parts except being EB.
EBJDs can not be bred from EB parents. It's an interesting genetic problem/question, but EB pairs do not produce viable fry. At least one parent has to be so-called blue gene JD (i.e. heterozygous for the eb gene and appearing as wild type).
