Hello, everyone! I have a 20 gallon freshwater tank. 78 degrees F. Sand substrate. I already have 3 panda Cory Cats and just added 1 male Dwarf Gourami. My tank is still new cycled as of about 2-3 weeks ago, so I'm slowly adding more fish. I was looking for some fun additions to my tank and wanted to see if anyone had any recommendations on what I could add next.
