So I have a 29g tank, lightly planted and was contemplating a final fish. I already have 9 rummynose tetras, 1 leopoldi angel, 2 sterbai corys ( will be going to a friends tank soon), 1 spotted Raphael, 2 bumblebee catfish, and a gold tiger pleco. What would be a good final addition, and try and keep it South American as that is the tank scheme lol.
