its possible, not at first though, once your jag gets comfortable and he realizes who he can push out of a home then yah your pecking order will probably change.. from time to time my jag will make my 2 oscars wait if theres food in the tank. but because of the 4 inch differance and the fact that my oscars weigh about 3 pounds each if not more, they dont take it from the jag... its fun to watch . well i hope ive been of some help. im sure your jag will have no problem addapting to its new home
