I had to move my tank that my julies were in to the other side of the room. After the move the smaller one (I think the smaller ones are males) started getting beat up on and chased around by the other one. They had recently spawned about a month ago and never ever had any problems between the two of them before. Should I put the other one in a separate tank for a while or should I wait it out and hope for the best. Its getting pretty bad.
