Nothing special pretty common actually that is just a female JD in a mood they can turn black like that when stressed angry or some times for seemingly no reason when young



lol she hasnt been stressed out for 6 months straight.
 
if these stay really dark, why isn't anybody breeding them? These guys look awsome. I like the normal ones too, but these look exotic as all get out.

ill try and breed it with the other guy that has a black one in fall river

lol....sounds like a plan.....by the way what city are you from?? i bought my black JD in new bedford.....where did u get yours??

to be honest i think it is a new strain that may be localized the the area or a certain supplier...it is possible the supplier is attempting to create a new color morph and that a few get through unoticed.....after all ist that the case with the EBJD......

nope, not at all... They were more 'stumbled across' than developed... Here's the article explaining... http://www.elacuarista.com/secciones/tfhblue.htm

We cannot "create" a genetic mutation such as albinism, leucism or whatever ism the Blues are. We can only find them.

We can find fish with desirable traits and breed them with other fish with similar desirable traits to further 'bring out' such desirable traits. This is what is meant by 'line breeding'.

Or we can find fish with an 'ism' (or genetic mutation) that makes them special and follow the proven path of producing offspring with the same ism.

In my experience, a confident, strong, healthy Dempsey will get and stay dark and some will even get jet black. But take the same fish and put it in a dirty tank with stronger aggressive tankmates and you'll turn it into a much much paler fish.

I think all this talk of "Black Dempseys" as a "new morph" or "genetic mutation" is potentially misleading speculation... Enjoy your happy, healthy, confident & beautiful fish, but no need to fabricate some justification for it.

that makes sense and all but i had him during a period in one tank where ammonia was through the roof. i couldnt figure out what the issue was..we concluded the bacteria must have died off.so in a sense he went through a whole cycle...and did i mention he lived with 6 5" rbp? and he was darker than anything through all that...so i dont know:nilly::grinno:

well that is what i was saying...just not in so many words.... anyone who has taken a bio class knows mutations apear naturaly....lol... but line breeding can cause them to stand out much more over time.... like the case of all "domestic breeds"...
but in all reality your sepeculation is unfair to all who have these black fish.....unless u know every breeder you cant honestly say there is no possible way fot there to be a line of black JD..... just as i cant say for sure there is.... your opinion is pure speculation as is mine!!!!:D
 
the really dark ones deff lighten up as they mature cause both of mine were super dark and now there about 4 inches a piece and ther are there normal brownish color
