The Cubicus Boxfish is also referred to as the Yellow Boxfish, Polka Dot Boxfish, or Cube Boxfish. The juvenile form is easily identifiable as having a yellow box-shaped body with brown spots. As an adult, the yellow will fade and become brown. The Cubicus Boxfish is sometimes confused with the Longhorn Cowfish, Lactoria cornuta which is occasionally also called the Yellow Boxfish.

Use caution if placing the Spotted Boxfish in a reef tank as they will often nibble at tubeworms. If stressed, the Cubicus Boxfish releases a poisonous substance, called ostracitoxin, from its mucous glands which will kill other fish in the tank very quickly.

When first introduced, the Cubicus Boxfish prefers a diet of live or frozen brine shrimp or bloodworms. Once acclimated, the diet should include chopped squid, clams, mussels, and herbivore preparations.
