I am going to start a 55 gal. discus tank soon. I was wondering if I should go with a pair of 2 snakeskin and a pair of red marble discus or go with 4 snakeskin so they will breed. I understand it is a very low chance to fins a male and female then even lower chance to find two that will mate with just buying 2. So should I just buy 4 hoping they will have at least one good pair? I mean if its low for either to happen then I will just go and buy a pair of both cause it would be a little more interesting
