I need some more suggestions for a "centerpiece" fish for my 29 gal. I have Sterbai Corydoras, 1 Male Dwarf Gourami, 1 female Platy and Amano Shrimp. I am hoping to add some RCS down the road. I love all the fish I have in there, but I really want a fish that will swim around the front and top part of the tank. I think my Gourami thinks he's a Cory Cat cause he swims with them all day long and the Platy just does her own thing. Any suggestions? Here's a pic of my tank.
