Unfortunately, I don't have another tank capable of housing the EBJD's (the other tanks are small planted tanks with tetras and shrimps).
I do realize the risk and in retrospect, wouldn't have done it. But as in all things, timing is everything. When I didn't have so many large fish in the tank, I couldn't get any EBJD's and then all the other fish came (they were rescues or cheap additions) and then I found these wonderful EBJD's.
It's ok, I don't need them to be dominant. I always expected the O to be dominant. What I might end up doing if I can convince the wife is to rehome the EBJD's in their own 75 gallon tank upstairs if I can.
