I was wondering what the deal is with beta's. I am looking to add one to my 10g tank and I was wondering if he would do well. I dont want to get one if they have to be in those small containers in the tank, it makes me sad (i dont care what anyone says). So my question is, will he do ok in open water in a 10g tank and what is the deal with getting two, will male/male fight or will female/male fight, or will any of them fight no matter what?
