The Blue Lined Rabbitfish, Siganus puellus, also known as the Scribbled Fish, features an absolutely stunning yellow body with small blue squiggles all across and a characteristic blue "mask" stripe over its face. These small squiggles are sometimes said to resembled the intricacies of a circuit board. They are one of the most colorful Rabbitfish species found in the oceans. The Blue Lined Rabbitfish actually has venomous dorsal and anal fin spines, so you should take caution when near it. The dorsal fin has 13 spines and the anal fin has 7. . It should be housed with other semi-aggressive fish and can be kept in pairs. They may nip at some corals and should eat primarily a herbivorous diet.
