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.
