Can the yellow tang kill other fish?

A Pacific blue tang, commonly called a Dory fish from the Disney move "Finding Nemo," can typically be kept with a Hawaiian yellow tang. Yellow tangs can be aggressive towards other tangs with similar round body shapes. Since blue tangs have an elongated body, yellow tangs do not consider them a threat. Some tangs require a large aquarium; yellow tangs can grow to over 7 inches in length while blue tangs can grow up to 12 inches long. Juvenile blue tangs can be kept in smaller tanks up to 75 gallons but as they grow and mature they should be moved into larger aquariums.
