Can you house two BPs in a 40 gallon tank? Would it be better if it were male/female instead of having the same sex or does that matter? I have a small BP right now, only a couple months old. Next year I want to get another one and I'm not sure if I can put them in the same tank. I dont know if its bad to put a smaller BP with one thats already a little over a year old. I already have a female BP and want to get a male Bumblebee next year.
