The Scrawled Cowfish is a pale yellow in colour with blue spots as a juvenile, as they mature these spots break up into a pattern of blue dots and dashes across its body.
When possible, the Scrawled Cowfish should be the first fish introduced in the tank. They are best kept in a larger aquariums with some live rock for algae scraping. Use caution if placing the Scrawled Cowfish in a reef tank as it may nibble on tubeworms. When housed correctly, the Scrawled Cowfish is long-lived.
Similar to other boxfish, the Scrawled Cowfish's skin is poisonous and, when threatened, it will release a toxin lethal to other tank members, including other cowfish.
Since they are omnivores, the Scrawled Cowfish should be offered a variety of meaty and vegetable foods. They are slow eaters, and should not be housed with aggressive eaters.
