Hi everyone I have a 56 gallon column tank with plants and co2. I have 2 angel 10 cardinals 7 rummy nose 4 cherry barb. I had 6 balloon ram but over the past few months they have slowly died off. Ive hsd them for a couple of years now so from what I read that's the life span of balloon. I would like to replace them with reg ram not balloon. I was there 2 pair? If this isn't a good match maybe you could make some suggestions. I have plenty of schooling fish. I would like something around the size of rams if not ram. Oh yeah this tank has been up and running for 6 months but everything in it soil wood plsnts filters and fish vsm from my old 36 gallon.
