I would say that is also my experience the only time my jags were agressive was when they had eggs other than that they were very easy to be pushed around that was also my experince with the mota that I had back in the day. over all my opinion of the Parachromis fish are less than impressed. I prefer my midas and Festae to the Parachromis, and one day if I do get a big enough tank I am going to invest in getting some umbie and hopefully get a big blue male out of them.
