Electric Blue Jack Dempsey Breeding Project

  • We are currently upgrading MFK. thanks! -neo
Hey, I called that pet shop and the are selling splits!
So happy about that, so thanks heaps to Matt.
At least I know I can get them somewhere now.
Just gotta get the tank now. I'll post it up when I get it.

Not sure whether to get a 4 or 5 foot for the mumma and pappa?
Suggestions please anyone?
 
I got blue gene fry 6 months old>>> also growing out to breed ebjd.... Still like 60 left.. You're best bet would be to breed the female blue gene with the male ebjd.... How come nobody reads my ebjd project...:(
Oh well... If you want some real good quality blue gene babies let me know... Youre going to be waiting at least 6 months for that ebjd to mature to be ready to breed

Good luck with your project... best wishes
 
I spent 3 years or more dedicating several hundred gallons of tanks into breeding Blue Dempseys... beautiful fish and a fun project...

It's been pretty well proven that Blue x Blue is a lethal combination. I've done this with 3 different males and three different females. Every time the eggs were fertilized and hatched, but the fry died in less than a months time. All three males and two of three females were bred with non Blue Dempseys and their offspring did fine (the other female died before being bred elsewhere). I've also talked to several others with similar experiences and have not once heard of anyone who raised Blue x Blue offspring more than 6 weeks.

I personally strongly supported the theory that blue Dempseys were weakened due to excessive inbreeding. While I do still believe that inbreedign depression is a fact to consider, both through learning more about genetics as well as through practical experience breedign Blues, I no longer believe inbreeding is the cause of weakened Blues and blieve the mutated gene causes weakened Blue Dempseys.

I did find using "better quality" breeders yielded "better quality" offspring. But I do not believe that even many generations of doing this even coupled with extensive outcrossing, will erase all of the ill effects seen in Blue Dempseys.

It was highly suspected that Het Blue (BGJD) x Het Blue (BGJD) yielded better offspring. But I have seen zero evidence of this in my own breeding projects...

I suggest seeking out Het Blues (or split gene as you have called them) as well as creatign your own. Then use trial and error to determine what fish make the best mates for you.

You pairs of dempseys will do fine in tanks such as a 40 breeder (3' x 1.5') but full grown adult pairs will do much better in larger tanks (such as 4' x 1.5').

I had the absolute best success raising fry and grow outs in smaller tanks that were plumbed into larer systems. This allowed me to have very high water quality even while keeping many fish in a somewhat small tank.
 
Thanks, I got my male ebjd from a girl called sarah on the gold coast (australia)
And if it wasn't for me being all the way over here I would definitely take you up on that offer warrenda fish :)
As I've said before, I'm looking for a few female split gene who are slightly smaller than my blue. I know he's not mature yet which is why I will grow the female to the right size while my blue grows that little bit extra. And then I'll be able to hopefully find a match.

So an adult pair will be ok in a 4 foot then? I've been looking at 4x2x2's or 5x2x1's.
 
Yess :)
Finally reached the next step of my project!

Last night I bought a 4 foot tank (280 litres)
It's in great condition and I got it for $450.
Also came with awesome filters, a light, hood and stand, chemicals.. everything!
And fish! A heap of breeding plecos, bristlenose and yabbies.

The biggest pleco is about 25cm and worth $200, so if I wanna sell him I can make half my money back straight away :) Very happy about this.

Might let them keep breeding while I'm looking for mrs split gene.
Anyone got tips on raising baby bristlenose? Haha.

Chels
 
$450!? Jesus. I could get a tank that size for like $100.
