In males, particularly alpha males, the border is conspicuously wider. In female specimens, the border looks like it was drawn onto the fin with a fine line pencil. The only reliable method to determine the gender of this species in adult specimens is by examining the black outer border of the anal fin. When the red color fades or disappears entirely, it is an indication that the fish is seriously diseased. The upper half of the iris is an intense ruby red when the fish is in good condition. The eyes of the Lemon Tetra are a distinguishing feature of the fish. Lemon tetras possesses an adipose fin that in males may acquire a black border. The pectoral fins are glass like in appearance, while the pelvic fins are a translucent yellow, which in male specimens becomes more opaque yellow with black edges on the posterior. The caudal fin is mostly hyaline except for the males which acquire a gunmetal blue sheen. The anterior three or four anal rays are an intense, acrylic lemon yellow, hence their common name.
