Ya i think the agresor would be the jd, changing to a female might help but you could still have problems check first thing evry mornin and be prepared to have to seperate some fish
I've kept a larger jd with smaller grow outs. He never bothered them or attempted to eat the ones he could. I agree with jds being hit or miss. If your set on a jd get a blue gene or Ebjd they tend to be less aggressive as standard jds.
