The Spiny Rabbitfish, also commonly known as Little Spinefoot, has a light tan body color and yellow toned medium to dark brown markings that appear like intricate scribbled lines. When it is frightened, it will become pale or more brownish and can even appear to be ill.

peaceful fish, it will do well with most tankmates, even more aggressive fish since its venomous* dorsal spines will quickly let the other fish know to leave it alone. It cannot be housed with other rabbitfish, however, unless they are a mated pair. It is generally reef safe if well fed. If not, it may eat some corals. It should be fed algae, seaweed and other vegetable matter.

* = While their venomous spines are only used in self defense, they can cause extremely painful stings so caution should be exercised. Never pick them up by hand and be aware of them while cleaning the tank so that you do not accidentally bump into their spines. If you are stung, a visit to the doctor is recommended.
