I have a 7 inch male Rotkeil Severum in my 80 gallon tank. Right now he is currently housed with red irian rainbows, a blue acara, 2 keyholes, and a convict. The keyholes and convict are being removed from the tank. I would like to order a mate for my Rotkeil from Jeff Rapps, but I am not sure what else I could keep in the tank with them. Any suggestions? I would really like to keep my blue acara in the tank if possible.
