However, because of their natural appetite for invertebrates, many angelfish species are challenging to keep in reef tanks with crabs, shrimp, coral, and other invertebrates. Fortunately, smaller pygmy or dwarf angelfish are less prone to disturbing reef tank inhabitants. By ensuring these fish are well-fed and providing ample live rock and space, predation behavior can be reduced. Reef tanks benefit greatly from these angelfish's algae-consuming habits, vibrant colors, and active behavior. Here, we explore ten angelfish species most likely to coexist peacefully with reef organisms. Fun Fact In the wild, angelfish are omnivores, consuming both algae and invertebrates such as coral, clams, and shrimp. This natural predation can be minimized in aquariums by offering a diet rich in meat-based foods, vitamins, and minerals. Reef Safe Saltwater Aquarium Fish 01 of 10 Swallowtail Angelfish Japanese Swallowtail Angelfish (Female). Credit: Debbie and Stan Hauter The swallowtail angelfish (*Genicanthus melanospilos*) primarily consumes plankton and often feeds on diatoms and filamentous algae. This striking Japanese species is among the few genuinely reef-safe angelfish, as it typically does not disturb corals or invertebrates. Swallowtail angelfish swim in mid-water, not residing directly on reefs or near the surface. Species Overview Length: Up to 6 inchesPhysical Characteristics: Females show a yellow stripe on their back, a light blue body, and black and blue stripes on the tail. Males display an additional thick black line on the body and trailing tail fin, reminiscent of a swallowtail bird. 02 of 10 Coral Beauty Angelfish Coral Beauty Angelfish (Centropyge bispinosus), also named the Twospined and Dusky Angelfish. Credit: Brigitte Emme The coral beauty (*Centropyge bispinosa*) is a popular choice among hobbyists due to its vibrant coloration, resilience, and affordability. While it may occasionally nip at clam mantles and large-polyp stony corals, especially in smaller reef aquariums, providing ample live rock can significantly minimize such behavior. Species Overview Length: 2 to 4 inchesPhysical Characteristics: body and head is deep royal blue, highlighted with an iridescent orange to yellow color on its sides. 03 of 10 Fisher's Angelfish Credit: Keoki Stender Fisher's angelfish (*Centropyge fisheri*), one of the smallest dwarf/pygmy angelfish, generally exhibits less aggression compared to other angelfish species. However, individual fish may become territorial in smaller aquariums, especially toward more docile tank mates. Thriving in environments with diatoms or brown microalgae, Fisher's angelfish are best kept in aquariums with established live rock and abundant algae for grazing. Species Overview Length: 2 inchesPhysical Characteristics: Orange body with a thin, sapphire-blue outline highlighting the belly and anal fin; caudal fin is pale yellow; genders look similar. 04 of 10 Potter's Angelfish Credit: Casey Mahaney / Getty Images Potter's angelfish (*Centropyge potteri*) is generally docile but can become aggressive towards new tank mates once established. It might nip at large-polyp stony corals, zoanthids, Tridacnid clam mantles, and some soft coral polyps. However, when housed in a reef tank with plenty of algae for grazing, it is more likely to leave most corals undisturbed. Species Overview Length: Up to 5 inchesPhysical Characteristics: Body is a brilliant orange, with pale to dark blue; the caudal portions of the dorsal, anal, and caudal fins are a dark blue-black; genders look similar.

While generally considered reef-safe with caution, it may occasionally nip at clam mantles and stony and soft corals. Providing a larger tank with ample live rock can help mitigate potential issues. Species Overview Length: 3.5 inchesPhysical Characteristics: Pale peach-orange to yellow on its sides; black speckles on a background of blue behind the eye; dorsal and anal fins are blue-black while the caudal fin is yellow; horizontal swatch of silvery-white from mid-body to caudal fin. 06 of 10 Cherub Angelfish fish among invertebrates. Credit: Â chuckh / Aquaticlog The cherub angelfish (*Centropyge argi*) favors reef tanks over fish-only aquariums, yet it isn't entirely reef-safe. Care is advised when introducing this fish to a coral tank. It nips at coral for the mucus, not the coral itself, but repeated nipping leads to stress, causing the coral or clam to retract and potentially die. Species Overview Length: Up to 3 inchesPhysical Characteristics: Metallic blue body and yellow to orange on parts of the head only; genders are similar colored. 07 of 10 Lemonpeel Angelfish Credit: Jones / Shimlock-Secret Sea Visions / Getty Images The lemonpeel angelfish (*Centropyge flavissima*) is notorious for nipping at large-polyp stony corals and Tridacnid clam mantles. It may also consume some soft coral polyps and zoanthids. Therefore, like most angelfish, it should not be fully trusted in aquariums with these invertebrates. Species Overview Length: Up to 5.5 inchesPhysical Characteristics: Uniform bright yellow body, blue or white ring around the eye, and dark-blue edges on the vertical fins. 08 of 10 Flame Angelfish This is a brilliant specimen. Credit: Our Marine Species The flame angelfish (*Centropyge loricula*), native to the tropical Pacific reefs of Oceania, is not readily bred in captivity, yet its wild population remains stable. Considered reef-safe, it adapts well to a commercial fish food diet. Coral or clam picking often results from inadequate feeding and can be mitigated by providing Mysis shrimp or frozen clams. Species Overview Length: 3 to 4 inchesPhysical Characteristics: Bright orange-red with a vertical elongated black spot and four or five bars on the sides; the posterior part of the dorsal and anal fins have alternating purple-blue and black bands; males are often larger and slightly more colorful than females. Continue to 9 of 10 below 09 of 10 Orangelined or Eibl's Angelfish Eibl's or Orangelined Angelfish (Centropyge eibli). Credit: Christian Martinsen One of the larger dwarf or pygmy angelfish species, the Eibl's angelfish (Centropyge eibli) adapts well to a peaceful aquarium environment with plenty of hiding places. But larger individuals may act aggressively towards smaller fish, particularly when confined in a small aquarium. Species Overview Length: 6 inchesPhysical Characteristics: A pearlescent body with several vertical, evenly-spaced orange to red stripes; a brilliant sapphire-blue stripe outlines the caudal fin. 10 of 10 Masked Angelfish Masked Angelfish (In transition to Male Phase). Credit: Keoki and Yuko Stender The stunning masked angelfish (Genicanthus personatus) are somewhat aggressive; they require a minimum tank size of 150 gallons. In their wild habitat around Hawaii, they are found at great depth, but captive-bred individuals have adapted to surface water pressure. With sufficient live rock, these fish will not bother your invertebrates. Species Overview Length: 8 inchesPhysical Characteristics: Like all marine angelfish, the young fish all start as females and the dominant fish will become a male. The young fish remain black and white, but when becoming a male, their black masks becomes smaller and they get yellow-orange coloring on the head, and the fins become orange. FAQ Are all angelfish reef safe? Not all angelfish are reef safe. While some species are less likely to harm your invertebrates, many have a tendency to nip at corals or other marine life. What angelfish are the safest for a reef tank? Dwarf or pygmy angelfish species such as the Swallowtail Angelfish and Coral Beauty Angelfish are often considered safer choices for reef tanks. How can I minimize the risk of angelfish harming my reef tank? Ensuring that your angelfish are well-fed and providing plenty of live rock for them to graze on can help reduce the predation of invertebrates.
