Flowerhorns have the following advantages over other cichlids:

They are relatively gentle with unrelated species. I've kept my Flowerhorn "Bebe" with small gold barbs, Leporinus and Cory catfish.

Flowerhorns are more colorful than many more common species of cichlid.

Most importantly, no two Flowerhorns will be identical. You could own a Texas Cichlid for example, but someone else will have one just like yours.

They readily accept pelleted foods so you don't have to cannibalize goldfish or guppies. This makes your fish healthier because they don't catch diseases from their food. Easier, too, to keep a can of pellets than a fishtank of live food.

They max out at thirteen to fourteen inches so they're comfortable in the common 55 and 75 gallon tanks.

Cool: You can usually tell when they're "young" if they will be quality or not.
