I have not had a tank for many years and feel like a newbie. I realize a 10 gallon tank is small. I love the dwarf gourami and am asking those with experience the question posted above. Can I humanely care for two dwarf gourami in a 10 gallon tank? Should one be male and one female? Both male? Is there a kind of plant they like? All I have now is a floating hornwort. No fish yet. I don't want to cause harm or suffering to my fish. Thank you in advance.
