He's in a peaceful tank I had to get rid of a firemouth that was picking on him. I do feed him sinking food since I got rid of the firemouth the robertsoni seems happier and less schidishProbably around 3". They get much better with age. I've had my female for almost 8 years now. They typically max out at 8" in size, but I was shocked when I measured mine out of water at 10" TL. They won't eat floating foods so sinking pellets are needed. Also they are very peaceful cichlids. Even oscars might be too aggressive for them. This is by far one of my favorite fish I have owned. Also a sand substrait is best as they are earth eaters.
