Not a hybrid.

But personally i have serious doubts of its purity, one would think that by now someone would have manged to get ebjd from a pure JD pair.

They do come from regular JDs. Its a recessive trait of JDs as it has been mentioned earlier. They aren't hybrids. In the wild these smaller, weaker, and more visible offspring would be easy prey. I believe that they do occur in the wild. I just think that the numbers of natural EBJD in the wild surviving to adulthood are drastically low. The numbers aren't just large enough for them to be seen and collected in the wild. Just think of the stories that you hear about one in a million animal specimens found with different colors and sizes from their normal form. In captivity those same rare traits can be easily reproduced through selective breeding. But this is just my opinion.

the whole point to a recessive gene is that it cannot be passed unless both parents have it, but it has nothing to do with "purity" . . . if either or both parents don't possess the gene, it will not happen

there are basically three possible methods to produce EBJDs:

1) two JDs that have the blue gene
2) one blue-gene JD and one EBJD
3) two EBJDs

the first two are the most common methods, while the third is problematic. EBJDxEBJD offspring seldom (ever?) survive, and I suspect the level of in-breeding to get this point might be part of the problem

If you think they happen in the wild it should have happened in the hobby right. Some JD breeder should have got a one in a million ebjd from two normal breeding jds.

Like others have said this would only occur if the parents carried the recessive blue gene. Even then, as mentioned ebjd will be out competed unless separated from their standard counterpart. Therefor, one would not rear any EBJD offspring if they left the spawn unseparated.

I think it depends on the country and area....iv seen some dodgy looking fish in some fish shops.

Where did the recessive blue gen start.

it would have to be some blind luck that two natural JDs happen to be born with some genetic anomaly find each other and breed and create ebjds.

Mine is tough as nails and really confident, he competes for food with a Breeding Pair of Red Dragon Flowerhorns that are twice his size, a king kamfa flowerhorn, a Rose Queen (like a pearly version of a red devil), 2 normal JD's, a extremley horny and agressive male Texas cichlid, breeding convicts,Blood Parrots, Firemouth, Yellow Labs and a Vieja Bifaciatus.

So pretty much he is hanging with every nasty cichlid you can think of (except for Parachromis species...before someone says lol )

And he is still eating good, no nips in his fins or gills chasing them around when they enter his territory, pretty much on level terms with everything else.

And he is still in the grow out tank (90g) waiting to go in his own partition with a load of Severums in my main monster tank, but he is so ballsy, i may even keep him in with the monsters long term.

So yeh, i don't advise what i have done, it was more of a issue of friends buying me fish as presents for my birthday lol! but.... he is full on hardcore, and i believe the modern EBJD's being sold are farrrr far more tougher than the old ones they used to sell with the spinal and eye deformitys.

He is also growing as rapidly as the 2 other JD's in there, so cool fish all round

 

[JacobWhitley]

they are not hybrids blues are made from a gene like the redhair gene

 

[apennell07]

i have a JD that supposedly carries the gene and cost twice what normal JD cost. if i remember right u breed it with a normal jd and 25% of the fry are ebjd. sadly i dont have another jd to try this with. you could make some real money off the fry at 30-40 bucks a peice. btw my jd is amazing looking. the other night he was purple! and then instantly changed to green! never seen anything like it. hes also an axe murder lol. kills everything. dunno if any of its due to the EB gene

yup i have one that is 6" now.
