Electric Blue Dempsey M or F?

  • We are currently upgrading MFK. thanks! -neo
Well, doesn't matter anymore. The BJD stopped eating,breathing heavy and then died. This is the second bjd one to die on me. Are these fish just really really sensative? This is the second one to just go belly up on me. There are plenty of other fish in the tank that are fine and the parameters seem good.
 
Blue JDs arise from selective inbreeding for weak physical traits, and its pretty common to have them die for no apparent reason... you're hardly the first guy to have this problem.
 
Thats the sweetest (small) EBD I think I've ever seen.... Nice fish :thumbsup:
 
Most of the blue jacks are males. Take a look in my photo gallery. My blue jack is in the tank with angelfish,parrots,balasharks,clownloaches,giant danios.and austrailan rainbows. Normally a jack dempsey would have killed all of the fish I just mentioned.But he gets along wiyh everyone because of his breeding,coloring,etc.

naw, only fish at risk from a normal JD would be ~2" giant danios and rainbows. anything much bigger than that would be ignored.

you are way off. regular dempsy are mean mother $%#^ers. i have one about 4 inches and he has already killed a couple plecos bigger than himself. my cousin put a 5 inch dempsy in with 8 pirahanas that were 6 inches + the dempsy beat them all down and had to be removed. i had two regular dempsy with a blue dempsy, needless to say aggression was high, i tryed to add dithers (zebra danios) and the regular dempsys immediatly killed and ate them. the blue later died when the water got too hot

the four I've kept, 2 males 2 females, ranging from 4" to 8", all bought at different times and different places, have done very well with 2"-3" high-bodied tetras plecos gouramis and other such inoffensive fish, and I've read of plenty of accounts of others having similar setups with their JDs. They are fairly voracious as small juveniles but as they exceed 3" they often do well with nonthreatening too-large-to-easily-swallow fish, excluding other cichlids. What size tank was yours being kept in?
 
my four incher was in a 55gal, cousins pirahana tank 75, two small regular dempsy & blue dempsy 30 gallon oct, just bought a 7 inch male at petco because he was labeled as a 2 incher for $1.98 so far the only aggression is towards the smaller (4incher) female hopefully they will kiss and make up
 
They are a naturally occuring color morph. As far as being weaker, they were initially when they were first being propogated but that is no longer the case. If you breed blue dempsey x blue dempsey you will get lower survival rate, however breeding regular x blue yields stronger offspring. They tend to be less aggressive however every dempsey I've had can't hold its own with other cichlids.

blue + blue = weak soon to be dead fry if you are lucky enough to get a female
blue + regular = regular looking fry carrying the recessive trait to be blue

you have to then take those fry with the recessive trait and mate them with each other or a blue dempsy to get blue fry. they are a weaker mutation of the dempsy there are plenty of threads talking about how peoples blue dempsy died for know reason. the water in all of my tanks got to 86 one weekend and out of all my fish the only one to bite the dust was the blue
