I have a 46 gallon bowfront with 3 Bolivian Rams, 6 Rummynose Tetras, 7 Rasboras, and 6 Burmese Border Loaches. What else could I add to this tank? I'd like to add another school of bigger fish if I have room. Also, what are some suggestions for some bigger peaceful community fish that would get along with mine? I like Rosey Barbs but am kind of interested in trying something else
