The Lemon Butterflyfish, also known as the Milletseed Butterflyfish, or Millet Butterflyfish, is mainly yellow with many dark spots on its sides forming vertical stripes. It has a black bar through the eyes and its fins are yellow.

The Lemon Butterflyfish is a good beginner fish that requires plenty of room to swim in a 50 gallon or larger aquarium containing a peaceful community. It may be kept singly or in pairs if introduced into the aquarium at the same time.

Its diet should consist of finely chopped meats such as marine fish, crustacean meat, and mysid shrimp. A vitamin formula with the meats will keep the yellow coloring bright.

Like other butterflyfish, they are generally compatible with: Dwarf Angelfish, Large Angelfish, Anglers & Frogfish, Anthias, Basslets, Batfish, Blennies, Boxfish, Cardinalfish, Clownfish, Filefish, Goatfish, Gobies, Grunts & Sweetlips, Hawkfish, Hogfish, Parrotfish, Pseudochromis and Puffers.
