Chaetodon quadrimaculatus (Gray, 1831). Not to be mistaken as the similar named Foureye Butterflyfish (Chaetodontidae capistratus). Quadrimaculatus means "four", which gives this fish its "Fourspot" name.

Characteristics & Compatibility:
The Fourspot Butterflyfish is a very active, but rather shy species. If startled or frightened this fish will dart around frantically. It is powerful, can jump quite well to avoid getting caught, and caution should be used when handling this fish, as its top dorsal spines can inflict a rather nasty poke. Even though some individuals will adapt well to aquarium life when placed in a amply sized, adequately sheltered, peaceful species tank community, others can be difficult when it comes to getting them to eat and may need coaxing to stimulate an interest in feeding.
Diet & Feeding:
Although this fish can be fed typical aquarium foods suitable for Butterflyfishes, this species feeds on small polyped stony corals, particularly Pocillopora sp. in nature. Offering live foods, a few live rocks with some encrusting invertebrates and algae growth on them, especially filamentous algae, will help this fish to adjust to its surroundings.
Reef Tank Suitability:
Not recommended due to its appetite for coral polyps.
