The French angelfish (pomacanthus paru) varies a lot from its juvenile stage to its adult stage as can be seen on the first video below. When at its juvenile stage, it has a rather dark robe crossed by 6 vertical yellow bands which disappear as it evolves toward its adult stage. He feeds on sponges, gorgonians, tunicates ... and he lives in the Atlantic West, from Florida to Brazil and the Caribbean Sea.
At the juvenile stage only, the French angelfish can be easily confused with the gray angelfish (gray angelfish or pomacanthus arcuatus). The latter is however rarer. They can be differentiated with the caudal fin, rounded and terminated by a thin yellow stripe for the French angelfish while it is straight and terminated by a transparent band in the gray angelfish and also with the yellow band that goes between the eyes and stops on the upper edge of the mouth for the French angelfish but crosses the mouth to continue to the chin for the gray angelfish.
In the adult stage, it is much easier to distinguish between them to the extent that the scales of the French angelfish are bordered with a slight touch of yellow while they are uniformly gray for the gray angelfish. In addition, the pectoral fins of the first angelfish are yellow on the inside while they are yellow on the outside for the second angelfish.
