I saw a 66 gallon hagen tank with stand and hood a few days ago and am strongly considering buying it. The tank measures 48x16x20. I was thinking of keeping a GT in it, what else should I stock it with? If not the GT, what SA/CA cichlids should I add? Also I was wondering what would be a good filtration setup for the tank? I was thinking of an AC 500 and an emp 280. Thanks
