Hi guys just wanted some advice about how many cardinals would look good in my 350l tank. The tank is 4ft x 2ft x 2ft. I already have 12 cardinals,a pair of blue rams, 5 ottos, about 9 shrimp and 10 pygmy corysdoras. The tank looks abit on the empty side and needs some more fish. It is filtered by 3x external filters,reana xp3, tetra tec 700 and 600.
