So I'm really thinking about taking apart my 48 inch tank that I can't find a top brace for and making a 8 ft tank and making me an office in my basement. The tank would be about 450 gallons 8'x 4' wide and about 2 feet high. One corner would be slightly curved or even at an angle due to basement wall. What would be good to stock in it? I don't like arroowana, and I kinda want peaceful fish as I don't want to deal with too much aggression I was thinking a big colony of frontosa but they grow slow
