I agree that most EBJDs are fragile but they are still my favorite fish. That is the main reason I've started collecting EBs and BGs from a few different sources. I'm trying to "better the breed" and get some hearty EBJDs to my area. It may take a long time and a lot of work but my goal is to breed for an EBJD that is just as hearty as a regular JD. I think a lot of people just breed them to try and make a couple bucks off a pretty fish with no regard to inbreeding.
