my female gouramis is pregnant . It has been about 3weeks now and is developing a black mark on her belly side and swelling around one of her eyes.The male and female were in a 120 gallon community tank , then we put them in a 20 gallon tank. Is the male picking on the female and may have hurt her. How long is the process of pregnancy fo the female? The male shows no attempt to build the bubble nest for the eggs. NEED HELP????
