Just curious, I'm growing out some BGJD and was wondering when they start maturing and I seperate the females from the males if the females normally get along with each other. Probably have about 3 or 4 in a 55 gallon by themselves.
In my exerience, territoriality is not related to a fish gender. Some say that EBJD are less aggressive, I have no experience with them. My regular female JD does not tolerate other fish in it's territory (36x18) unless they are smaller.
