Chaetodon quadrimaculatus has a yellow lower body, black upper body with two white spots, and an orange eye-bar with black and blue borders followed by a yellow bar.
Der Vierflecken-Falterfisch (Chaetodon quadrimaculatus), auch Vierfleck-Falterfisch, lebt paarweise im Pazifik von Südjapan bis nach Hawaii und Tahiti. Er hält sich nur in flachem Wasser von weniger als 10 Metern Tiefe auf. Er ist nirgendwo häufig.
Der Vierflecken-Falterfisch wird maximal 16 Zentimeter lang. Er frisst hauptsächlich Korallenpolypen, kann im Aquarium aber an Ersatznahrung gewöhnt werden.

The four-spotted butterflyfish or fourspot butterflyfish (Chaetodon quadrimaculatus) is a species of butterflyfish (family Chaetodontidae) found in the Pacific Ocean from the Ryukyus, Ogasawara (Bonin) Islands and Taiwan to the Hawaiian, Marquesan, and Pitcairn islands, south to the Samoan and Austral Islands and the Marianas and Marshall Islands in Micronesia.[2]
The fourspot butterflyfish is a marine coralivorous organism. Therefore, its noted geographic distribution, as well as population-level spatial distribution and temporal variation in density, is correlated to relative distributions and abundance of the corals that butterflyfish are dependent on for food.[3]
It is a quite distinct species, but most closely related to the speckled butterflyfish (C. citrinellus). Together they are basal in the subgenus Exornator, and might be intermediate between the core group of this subgenus and the species of the Rhombochaetodon (or Roaops) lineage. If that is correct, the latter would require to be merged into Exornator. If the genus Chaetodon is split up, Exornator might become a subgenus of Lepidochaetodon.[4][5]
Butterflyfish as a family are a common marine aquarium specimen as a result of their varying colors and patterns, and contribute to 4% of the global fish trade. [6]
As one of 90 extant species in the genus Chaetodon, the fourspot butterflyfish shares the following characteristics: a laterally compressed body with bilateral symmetry, and ctenoid scales, identified by their comb-like edges.[7] One defining characteristic of this species is its four rounded, eye-shaped spots, two on each lateral surface. These spots are theorized to help this butterflyfish avoid predation by either intimidating predators or diverting attack of predators to potentially less fatal regions of the body.[8]
C. quadrimaculatus is an obligate, hard coral feeder, an adaptation that is theorized to have evolved approximately 3.2 million years ago.[9] This species is highly dependent on scleractinian corals, an order of Anthozoa where approximately 50% of species are reef-building zooxanthellate.[10] Butterflyfish typically feed from corals by removing individual polyps while leaving the calcareous skeleton undisturbed.[11] They use a picking method where they grip prey with the tips of their upper and lower anterior jaws.[12] Due to their specialized dependence on corals, C. quadrimaculatus and other obligate corallivorous species have an increased bite rate, pointing to a higher feeding efficiency, than butterflyfish that are facultative corallivores.[13]
Owing to their obligate dependence on corals, fourspot butterflyfish tend to be distributed in stable feeding territories with high fidelity for each site and male-dominated defense mechanisms.[14][15] The social structure is dominated by heterosexual, adult pair-bonds, while juveniles are typically solitary. [16][17] However, there have also been observations of homosexual pair bonds and pair bonds between sexually immature butterflyfish in this genus.[18] Therefore, the evolution of pair bonds may offer benefits beyond increasing reproductive fitness.[18] Other proposed advantages of pair-bonding include increased foraging efficiency and vigilance against predators.[13] Within heterosexual pair-bonds, evidence supports the evolution of sex-specific roles rather than mutual territory defense.[19] In this division of labor, males actively defend territory allowing females to successfully forage and therefore increase their fecundity.[15]
Fourspot butterfly fish typically reproduce in monogamous pair bonds.[16] They reproduce via spawn breeding where the gonochoristic males and females release their respective gametes into the water column for fertilization.[20] Eggs are typically less than 1 mm in their pelagic form and fertilized eggs hatch in approximately 30 hours.[21] Like other butterfly fish in this family, C. quadrimaculatus has a specialized larval state called tholichthys, where the head is covered by fused plates, giving rise to a distinctive head spination.[21] Although no definitive results have been collected, there is little to minimal or no parental care in this species as a result of their spawn breeding reproductive tactic.[16] After larval development and hatching, juveniles directly settle on coral which offer protection from predators.[22]
Since fourspot butterflyfish are highly associated with scleractinian coral, they are an indicator of reef health and their relative abundance is contingent on coral reef abundance.[9] With recent global changes in climate, especially the 2015-2016 rise in water temperatures and mass coral bleaching event in the central Indo-Pacific, this species may have experienced a decrease in food resource. [23][24] Large-scale coral bleaching has also been associated with decreases in both interspecific and intraspecific aggression in butterflyfish.[24] Research in other species of butterflyfish show that local coral bleaching does not have immediate effects on local population abundance of butterflyfish, but does lead to sublethal effects such as decreased growth and reproduction rates.[25]

Chaetodon quadrimaculatus es una especie de pez mariposa del género Chaetodon.[1]
Es más conocido como pez mariposa de cuatro manchas debido a sus cuatro manchas blancas, dos en cada uno de sus perfiles, que tiene en el cuerpo, que a simple vista brillan como diamante. Es de color amarillo-anaranjado, y marrón en el dorso y en su franja que tiene atravesando sus ojos. Alcanza hasta 16 cm de longitud.
Prefiere vivir solo o en pareja, en arrecifes coralinos a entre 2 y 15 metros de profundidad. Abunda en las costas del Océano Pacífico, incluyendo las islas como Hawái.

Chaetodon quadrimaculatus, thường được gọi là cá bướm bốn chấm, là một loài cá biển thuộc chi Cá bướm trong họ Cá bướm. Loài này được mô tả lần đầu tiên vào năm 1831.
C. quadrimaculatus xuất hiện trên khắp vùng biển nhiệt đới phía tây bắc và trung tâm Thái Bình Dương, từ đảo Đài Loan về phía bắc tới miền nam Nhật Bản, bao gồm quần đảo Ryukyu, quần đảo Bonin và quần đảo Izu, phía nam trải dài tới Polynesia. Một số cá thể đơn lẻ đã được tìm thấy ở miền đông Philippines và quần đảo Solomon. C. quadrimaculatus được quan sát là sống chủ yếu xung quanh các rạn san hô lộ thiên, ít khi sống trong các rạn san hô ngầm, thường sống ở độ sâu khoảng 2 – 43 m, nhưng thường tìm thấy ở khu vực nông hơn[1][2].
C. quadrimaculatus trưởng thành dài khoảng 16 cm. Thân của C. quadrimaculatus có màu vàng tươi với chi chít các chấm đen. Gần nửa thân trên là một khoảng màu đen với 2 đốm trắng ở mỗi bên thân. Phần mõm ngắn và nhọn. Một dải màu cam viền xanh nằm băng qua mắt, kế đó là một dải màu trắng nằm ở nắp mang. Vây lưng và vây hậu môn có một dải hẹp màu xanh lơ. Các vây đều có màu vàng như thân. Cá con có hình dáng giống với cá trưởng thành[3].
Số ngạnh ở vây lưng: 13 - 14; Số vây tia mềm ở vây lưng: 20 - 23; Số ngạnh ở vây hậu môn: 3; Số vây tia mềm ở vây hậu môn: 16 - 18[2].
Thức ăn của C. quadrimaculatus chủ yếu là các loại san hô thuộc chi Pocillopora. Chúng thường sống thành đôi (khi giao phối) hoặc đơn lẻ[1][2].
C. quadrimaculatus thường được đánh bắt để phục vụ cho nhu cầu nuôi cá cảnh[1].
