I don't have pictures ready for the parents right now, but you can clearly see them in a small vid I posted on Youtube
http://www.youtube.com/watch?v=5geoDdXB9ME&context=C399de37ADOEgsToPDskICkEcIDexnJiM1Gjx_02Dn

The fry are much bigger now & I've meant to update that video, but I've been too busy to edit video.
I rushed & posted that video just to show the spawn. The parents are young adults between 2 1/2" - 3" & are about a year old. This is their first spawn & it has some impresive results.
I have other bggg's I'm pairing right now with other bggg's, ebjd's & gold JD's to see what difference I'll get in fry.

I also have a friend I'm getting some other Green JD's to diversify mine & do some more projects. They'll be here Thur. :)

I have other vids you can view on my channel & I have more footage I'll update it with when I have time. But I won't rush a vid on there anymore because I was disappointed with my last one.
Here's my channel if you or anyone else would like to view.

Thank You
and please comment on Youtube

Update-

Sad news... The heater in the fry tank these babies were in quit working a couple on nights ago.:nilly:
Sadly most of the fry died,:cry: but I managed to save a few.:clap The (12) survivors have a new heater & doing well.
I will post pics soon, but I wanted to let everyone know what's been happening here.

I have 2 other pair of bggg's that are fixing to spawn :lol2::lol2: & I will expect more Green JD's from them. I will keep everyone updated with this project as things progress. I have a few other projects that I'm working on & patiently awaiting results from those too.:popcorn:

I also picked up a few other Green JD's from liquidlizard to diversify mine :clap & will be returning the favor as soon as these grow a little more. If anyone is interested in grabbing a few of these babies I recommend PMng her for order/shipping info. I highly recommend her bloodline.:thumbsup:

Thank You
Jill;)
 
Sorry for the loss, but this is very cool. I love stuff like this. We are friends with the original breeder of EBJD's (no he's not dead). He said the original blue was actually purple. He's here in the US now working on that project.

Thank You for your simpathy. The remaining (12) babies are doing great. :)

It's also great to know that the founder of the Electric Blue Dempsey's is still working with them. If I'm right they discovered them by accident around1985. A man named (Hector Luzardo ) raised them EBJD's separate from their Wild Type brothers/sisters & found out they grew slower than their Wild Type brothers/sisters. I'm not sure if this is the person you know, but I'd like to know the name of the person you know to be the original breeder of EBJD's.

Thank You for your interest & keep me informed with your friends Purple JD project.

Hey all,

Greg(theCrazyFishGuy) here! Just wanted to check in and say hello. Jill and I have been e-mailing about this project for some months now, and I wanted to give her kudos for being so persistent and getting the results she has achieved so far!

I had originally stumbled upon the theory behind this gold & blue Dempsey mix on another forum (the now-defunct bluejax.co.uk, I believe), which was used as inspiration to gather some notes and post my blog entries on EBJDs (http://wp.me/p146ri-r) and "green" JDs (http://wp.me/p146ri-5n).

As you now know, what we're calling the "green" JD here is the result of a fish that displays both the recessive trait for electric blue, plus the recessive trait for gold colouration as well. There have been other names popularized, but they all refer to the exact same combination of the two traits. These names include: 1) blue & gold JDs, 2) "green" JDs, 3) powder-blue JDs, and 4) platinum JDs, among others, I'm sure.

I want to take a moment to comment on my choice of the word "green" to refer to this fish that displays both the blue and gold traits. The quotation marks are used very deliberately. The word was chosen as a reference to subtractive colour theory, where cyan (aka electric blue) and yellow (aka gold) combine to produce the colour green. Perhaps calling this fish green is a misnomer, since it will be in no way green-coloured, instead appearing a paler shade of blue when compared with EBJDs, however, now you know the logic behind the choice.

As for the other terms, the first is obvious, albeit a little clumsy to say. The term platinum JD is borrowed from angelfish genetics, where similar recessive mutations (pb - Philippine blue and dng - dark new gold) combine to result in a brilliantly iridescent white fish that we call the platinum angelfish. While I agree with the similarity in the combination of gene mutations, I think it's a poor description of the end result, certainly worse than "green" is. I think powder-blue JD is probably the most visually accurate description, though it may lead to confusion with the similar-sounding electric-blue JD. I have one more idea for an alternate name, but I will sit on that one for the time being.

Anyway, hope that clears up any confusion about the naming and colouring of the "green" JD! With a little patience and a steady photography hand, I hope Jill will be able to share more of her results and give a clear picture of what this fish actually looks like in adulthood.

Cheers!

-- Greg

PS. I'd also read that Hector Luzardo is no longer alive. I believe he passed away around 2004. Is this not the case?
 
Hi Greg,
Thank You for posting here. This is your project I'm working on & the babies that are left from this first spawn are coming along beautifully.
I will have to take some new pics & update this thread.

I hope you decide to add your (blog) to your MFK membership & share all the breeding projects you have with everyone here.
I know a lot of members here would love to read your blog.

As for Hector Luzardo being alive, I thought him to be deceased just like you mentioned in the early turn of the century. But a member here posted that they knew the person responsible for the EBJD's. I asked if they meant Hector Luzardo, but they never replied.

-Jill ;)
 
Hector Luzardo is dead. While many give him credit as the originator of the blue dempsey, he is not. The real originator is Alejandro Chemin. Alejandro discovered the first EBJD in a dempsey breeding pond many years ago. There was only one. I will have to ask Alejandro how Hector came into the picture and why he seems to get the credit.

Although I have a very hard time understanding him as I don't speak Spanish (sometimes his wife has to translate), he is very interesting to talk with. Very knowledgeable when it comes to breeding fish. He now has a farm here in FL with about 80 large breeding ponds.

My son knows a lot more than I do when it comes to this subject. He helped Alejandro move to the farm and then worked there with him for awhile. There are a lot of tricks he uses to breed the blue dempsey. I also know that most, if not all of the EBJD's he sells are sterile.

I'm not really interested in the project. My son moved from FL to Michigan and left me with a few male blues and a bunch of blue gene females. These are directly from Alejandro's stock and are not sterile. I'm not sure what I'm going to do with them yet.

Hi...
Thank You for replying & giving us the name of your friend ( Alejandro Chemin ). That's very interesting to hear about his discovery.
I still don't understand how Hector Luzardo received credit as the originator of the blue dempsey's w/out your friend Alejandro Chemin stepping in & contesting this find. It will be interesting to hear what he has to say about this subject.

Also, while speaking with Alejandro about Hector can you ask him how his progress is going with the Purple Dempsey's. I find it facinating that he can get that colour.
