Pterophyllum leopoldi

Pterophyllum leopoldi, also referred to as the teardrop angelfish, long-nosed angelfish,^[3] dwarf angelfish, or Roman-nosed angelfish,^[4] is a river dwelling angelfish species that originates from rivers in the Amazon River basin along the Solimões River, Amazon River, and Rupununi River.^[5] It is distinguished from other members of the Pterophyllum genus 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.^[3] The species was originally described as Plataxoides leopoldi in 1963 by J.P. Gosse,^[6] and is frequently misidentified as P. dumerilii when the species is imported in the aquarium trade.^[7] P. leopoldi is the smallest of the angelfish species and the most aggressive.
