It is distinguished from other members of the genus Pterophyllum by the absence of a pre-dorsal notch, and by the presence of a black blotch at the dorsal insertion on the 4th vertical bar.[1]

The species is frequently misidentified as P. dumerilii when it is imported in the aquarium trade.[4] P. leopoldi is the smallest of the angelfish species, reaching a length of 5 centimetres (2.0 in) SL,[3] and the most aggressive.

The specific name honours King Leopold III of Belgium, who sponsored the expedition to the Amazon that collected the type of this species.[5]
