I have a couple dozen EBJDs and I love them. In the begining they would die from simple mistakes because they are sensitive fish. My advice is do frequent water changes, and do not allow the ammonia level to ever get above .25ppm. Also, grow them either by themselves or non-aggressive cichlids since the EBJD is far less aggressive than their normal strain counterpart. The stress of tank aggression can kill them. When i raise them, I keep them together until one becomes dominant, and I remove that one out of the tank. believe it or not, I have 3 EBJDs living with my discus... that's how passive these guys can be.
