EBJD

  • We are currently upgrading MFK. thanks! -neo
my guess is severe inbreeding, maybe the breeder was selecting the bightest colored fish out of every spawn and breeding them with each other, like breeders do with dogs and such, and came accross this brilliant blue jd, but they have a secondary trait which causes the offspring to be fataly flawed, my guess is some sort of brain or spinal deformation, and when they get to a certain stage in development the deformation becomes deadly, my reasoning is that most ebjds have some sort of physical deformation as previously stated.

im not an expert by any means on genetics so if this sounds dumb i apologize.
 
^ I have found that a general description of these fish's health, appearance, and aggressiveness cannot be accurate as every ebjd develope with a great deal of variation. I've said it before that siblings from a spawn can be entirely different from one another in shape, color, fin length and shape, health and size, etc etc
It's very strange.
 
bully fish, great link to that old thread!!

Personally, I don't really care where they came from. It's interesting for sure, but I don't think the answer to the problem will be found there. It is relatively easy to select an individual gene to transfer around, whether from a breed or species. Further, as I elluded to prior, the hybrid theory does NOT makes sense due to the fact that it seems required to backcross to normal JD's to keep this thing alive. If it was a hybrid with chemistry issues, backcrossing would seem to make it worse, not better.

Without absolute documentation of every spawn, we really are just shootin the breeze. Progeny counts can be very misleading, especially if guesstimations are being made with pre-existing expectations. There is considerable overlap (in single spawn) between 50-50 and 1:2:1 with lethality with the actual stats count.

I am hoping to get an EBJD today. or 2. I currently have Texan, Firemouth and Salvini. I intend to intently make any and every cross I can and document and hopefully learn something.
 
So I'm a fledgling breeder. I hope to get some EBJD and would like to potentially start a breeding exercise with them. Currently I've been successful with red empress and demasoni to good effect. I'm very curious about stock I see for sale online. When you see EBJD for sale at a pet store vs through a local fish club how do they breed them to guarentee the proper adult coloration.
 
If you are going to get some ebjd with the intent to breed I suggest you get a small group if they are available, then you can grow them out and hopefully end up with one that is breeding quality. Good luck!
