Very nice line of EBJD's you have there. Typically, the dark color could be a sign of early stages of breeding. It could also be a dominance thing though.
If you have the room, you could separate your males and females. Put the BG male with the EBJD females and the BG female with the EBJD males. This would help your chances of getting an EBJD/BGJD pair.
Once the pair forms, you will likely need to give them their own tank. In the 210, tankmates may be fine but they will impact how many fry survive.
As for EBJDxEBJD, it has been attempted by a few people posting online. Like I said previously, it's never worked. At least no one has ever reported it working. I guess it is possible someone has a pair producing fry and not telling anyone about it but I doubt it. Typically, if the eggs hatch at all, the fry die within a few days.
