I have been keeping EBJDs for some years now.Originally started with 6-1 inch juvies from a lfs.5 of the 6 died,but the one that survived grew to 7 inches.I tried to find him a mate,but he would'nt breed.Had a feeling he was sterile.I traded him to a lfs for some red albino oscars(wish I kept him,he was a beauty)Last year got back into the EBJD thing again(after having a health issue).Got 3 EBJDs online,along with 6 Blue Gold Dempseys.They look more Gold than Blue.little bit of a disappointment.Took 3 of the BG dempseys and put them in a 29 gallon,the others I keep in a 90 gallon,with the EBJDs.All are about 2 1/2 inches.Then I decided to buy a mated pair of BG/GG dempseys online,along with 2 extra females.These are the ones that produced the Blue Gold dempseys,but in their spawn will also be some EBJD,Gold JDs,and Blue Gene JDs.The mated pair looks just like regular JDs.They have spawned 2 times so far for me.I lost the last batch of fry in October.But they spawned again last week and I decided to keep parents with fry this time.They are in a 46 gallon tank,parents and fry are doing fine so far.I do notice EBJDs do grow slower than regular Dempseys,and I would also suggest using a UV sterilizer when keeping these kind of Dempseys,as they are more sensitive to water issues and parasites.
