Lately, my male Golden Gourami has started to chase my female Golden Gourami and now her fins are ripped ( will they grow back? ) I don't know how to prevent this. I don't have another tank to put the dangerous male in, so what should I do? 

Yeah I saw your sig but it doesn't say what size your tank is. Why are you being so vague about the size? Even your profile just says "I have one tank".
