Electric blue Jack Dempsey

[Vorka93]

Hello

Can anyone give any advice regarding this species I'm finding conflicting information online some places say they are guaranteed to die in x Time while others say they are alot easier to care for now? I've had the regular JDs in the past with no issues.

How do these fish compare to regular JDs?

The tank I would be looking at putting them in would be a 240l 120x40x73cm

Would that tank be suitable? My LFS says it would fit 3 or 4 in for life but I'm dubious thinking he just wants to sell more lol, I thought it would be 1 max.

Thanks

They are still not as robust or free from deformities as regular JDs. It's still rare to have them get past 6". I would only keep 1 EBJD and dithers like swordtails in a tank that size.

Since EBJDs are a line bred form, where the main point of the selective breeding process was to enhance blue color, and save only the most blue individuals from a spawn, (as opposed to those with genes that actually promote health, and robustness), those healthier traits often got inadvertently sacrificed in favor of outward appearance.
And when these individuals with less than robust attributes are bred with other more blue, but wimpy individuals, the end result are progeny that get weaker and weaker over time.

In nature these wimpy individuals would get weeded out in the survival of the fittest mode, and would not get to reproduce .
Only in captivity are weak individuals allowed to survive.

Thanks for the reply. Palmer aquatics on YouTube basically said they are impossible to keep which makes me nervous about buying one as I can't think of a fish that looks as good around that size.

There are too many variables to quantify to say if a certain fish is strong or weak.

Five years ago I got a EBJD from the Wet Spot. I had him for about six months then gave him to a fellow MFKer. He then lead the life of a breeder with many mates in the process of creating Platinum JDs. He live for about four years and had many thousands of fry. He grew out to about 10in in size.

What I started with
Him at about six months old
And here he is at the 10in mark

Nice EBJD. I’ve heard mixed information in regards to their longevity, disease resistance and health. It’s cool to see one that made it to 10” (and looks great).

Everything im reading says they are genetically predisposed to all kinds of ailments....I would pass on having one.

You could always go with Electric Blue Acara(s). They’re as hardy/healthy as the traditional Blue Acara and display superb colors. I’ve kept them over the years and really enjoy the species. They’re a very inquisitive fish and always begging for food. The best part is that they do well in groups. Just a thought….

That looks great! How you just kept the one or have you had multiple experiences? Still seems like luck of the draw but they are a bit expensive where I live Maidenhead is selling them for £30 each. I'd be tempted to buy like 4 and see how it goes but it's a he'll of alot of money the other options would be gamble with online delivery but it's still £15 a fish and £20 delivery.

Thanks for the reply!

It certainly seems that way shame when they look so good!

Thanks for the suggestion I wasn't too keen on them when I have seen them. I was contemplating researching gold saums or a rainbow snakehead or smaller bichir if not an EBJD but the idea of a jumping fish scares me and I'm not sure if a gold saum would fit in the tank either.

Thanks again!
