So I have a friend who has a fish. And decided to give it to me because he knows I love fish. I am completely broke and don't have money to get a new tank and was wondering if a Sunburst Mickey Mouse Platy can live peacefully with my Dwarf Gourami. I am scared to even think about putting him in my 30 gallon cause I know he will get messed up by the other fishies. Also sometimes do LFS take homeless fish?
