T. aureum looks very much like T. elioti. My aureum are just juvenile and don't show any color. But I have a picture of an award winning aureum that I took at the ACA 2001 show. There is regional variation of color among aureum and elioti and don't count on mine as good as the show fish. Aureum and elioti are less aggressive than Firemouth and will get along well except that they may cross breed.
