Hi I am thinking of putting swordtails in my tank instead of platys. How many is the minimum amount of swordtails necessary for them to be happy? (my tank description is in my signature) I don't want any babies, cuz then I'll have to take care of them, so preferably I'd like to have all males. If this is not possible in my tank size, how many females minimum should I have to a male, and do I have to take care of the babies, or can I just let the other fish eat them (cruel I kno but I just don't have the space :-()? Please help!
