About a year ago I got back into fishkeeping after a little hiatus. I recently bought a 320gallon tank 8'x32"x2' which is now almost set up, still working on plumbing it. My plan was to transfer some moba frontosa from a 125 I have into it along with some other tangs. While fronts are probably my favorite fish looks wise, mine lack personality and are skittish. This has been my experience in the past especially with wild caught individuals (though these are f1s)but I couldn't resist. Anyways this leads me to my question. I really love big aggressive fish and they way they "interact" with you. I have never owned an umbee, but really have an itch to get one. The thing is I don't want a big tank with one fish. So my options to me at least are keep the fronts or set up a CA theme tank with an umbee as the centerpiece. However is this feasible or is the 320 just not big enough to house a few other cichlids long term with an umbee? Thanks for any input, especially those with first hand experience.
