Blue Jack Dempsey - Breeding Pair
- Thread starter ormed
- Start date
I didn't even know that MFK existed until this past weekend when "z24frank"... told me about it...
Thanks Frank! I've been on Cichlid-forum.com for a while and have been selling there, on AquaBid and to wholesalers and even a few to my lfs who pays me cash.
I'll gladly sell a few from my next batch here on MFK. in a month...

Can you tell the difference between the EBJDs and the BGJDs?
These fry are almost 4 weeks old and the BGJDs are begining to noticably outgrow their EBJD siblings. This was my first spawn of actual blues, so at the time, I didn't know to remove fry a little sooner, nor was I confident that I could distinguish between then 100%. I only got about 25% Blues from this spawn. Now I beleive the reason for the low percentage is because the parents likely started eating the slower blues and the BGJDs were out competing the EBJDs for food, causing many of the EBJD fry to waste away and die.

If anyone wants to view, bid, or watch the auction on my breeding pair of EBJDs, here's the link.

Jack Dempseys are tollerant of a wide range in pH. I've seen/heard of a range between 6.5-8.5
The main thing to remember with JDs, as well as any fish is that any pH adjustments must be made gradually. My tanks are at about 7.0 pH which is a bit lower than most, because the plants I have are continually decomposing, which acidifies/lowers the pH.

Here's how to produce Adult EBJDs starting with eggs (Theoreticaly, unless you are actually breeding them). For each step you can skip, you save about 12-14+ months, so the whole process takes about 3-1/2 years.
JD = Regular Jack Dempsey
BGJD = Blue Genotype (Regular Phenotype) Jack Dempsey
EBJD = Electric Blue Jack Dempsey
Step 1) EBJD X JD = 100% BGJDs
Step 2) BGJD X EBJD = 50% BGJDs and 50% EBJDs
3) note: EBJD X EBJD = 100% fatal (No fry survive, assuming any eggs hatch at all).
Bottom line is that to actually produce EBJDs, you need an EBJD to spawn with a BGJD. This is why most breeders are unwilling to sell BGJDs. If you pair one with a EBJD, you can save years of breeding, feeding and rearing time.

You have some serious Fish there brother! If you have some auctions, put em here or PM me, I would be very interested in a 3 pack for my grow out, eventually to move to a second 125.
Fantastic Fish! Many Kudos!
