Right now they are in a 6ft 125. I have a huge piece of driftwood, and tons of fake plants to try and give the fish their own territories, but the JD chases the Jag until he hides behind the filter output. The Freddy, JD and temporary channel cat all stay on the left side in some plants they like, so i made the Jag his own space on the far right, but the JD will go out of his way to pester the Jag. Now that the JD has had a time out, and the Jag has been given a break from bullying, I may try it again and see how it goes.
