I recently got a 20 gallon high tank. I have been trying to figure out what fish to put in it. I defiantly will be get some cories but haven't decided on other fish. I want atleast one school of fish. I also am interested in a dwarf gourami as a centerpiece fish but am open to other options. I would like to know what smaller fish can get along with the gourami. And if they can get along with tetras. Thanks for any help!
