I have a line on an acrylic 10 ft by 3 ft by 4ft tank for an excellent deal. My largest is 120 gallons. This would be a major leap. Would frontosa use all the space, or is it too deep. Maybe I could put haps and peacocks as well? Also, it has a overflow and closed loop system(was saltwater) and a few scratches. So I would have to learn about that, I have been using a FX5 on my 120. Any input? I just know that I want it, and I have to talk the hubby into it. I'll probably have to sell my 120 and 100 and 55, and jut have the one large tank.
