Tough to say without a good look at the lips, or a closed mouth to see the slope of the forehead. How big is it? It can be difficult to discern between the two until they're 6 or 7 inches. Since both species are considered to be established in the same waters, there could potentially be a lot of hybrids. Many of the ones you see in the aquarium trade are.
So I guess the question is does it fit either of these descriptions, or was it shaped like any of these pictures?

Unfortunately the color tells us nothing in terms of discerning between the 2 species. I know that originally people thought that red devils inhabited the waters near me in Florida, but they were later determined to be midas cichlids. But OP, you're the only one who saw it so you're probably the only one that can give us an answer!
