yes sir it is. If you get two electric blues to successfully breed, then the offspring won't last more than a few days typically. Which is why they need to be bred with a regular dempsey. Then the off spring of these two have to be bred back to the blue dempsey in order to produce that blue dempsey color trait.

check out the big brain on Benfica......
Oh, a blue JD x normal JD pair will produce 100% normal-looking blue-bearing JDs. These must spawn with a blue (50% normal - 50% blue offspring) or a sibling (25% blue - 75% normal offspring) in order to get blue babys. Gotta be patient...

These poor dempseys are more inbreed than an appalachian farmer. They really need to be outbred with black dempsey to strenghten the strain. I've had 5 in the past 6 months in perfect water conditions and they keep dieing. I now only have one left. BTW he's looks like he's got more black than the others did, and knock on wood he's doing well.
I read on cichlid forum by a guy who is breeding blue demps that female blue dempsey's are very rare.
They breed a blue to a normal, then the offspring back to the blue to produce blue demps
