Females display particularly strong striping, a dark-edged dorsal profile, white pelvic fins, and a finely spotted or patterned tail, giving them a clean, high-contrast appearance that stands out beautifully against reef rockwork.\u003c\/p\u003e\n\u003cp\u003eNative to the Indo-West Pacific, this species occurs from the Indo-Malayan region east to Vanuatu, north to southern Japan, and south to the Great Barrier Reef. In nature, Lamarck Angelfish inhabit reef crests and deeper reefs near steep slopes, where they often swim above the reef and feed on plankton in the water column.\u003c\/p\u003e\n\u003cp\u003eUnlike many larger angelfish, \u003cem\u003eGenicanthus\u003c\/em\u003e species are primarily planktivorous and are among the more dependable choices for a reef aquarium. Their generally peaceful temperament, active swimming behavior, and excellent reef compatibility make the female Lamarck Angelfish an attractive centerpiece or community saltwater fish for a spacious reef or fish-only aquarium.\u003c\/p\u003e\n\u003ch2\u003eQuick Care Guide\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eCare Level:\u003c\/strong\u003e Moderate\u003cbr\u003e\u003cstrong\u003eMinimum Tank Size:\u003c\/strong\u003e 125 gallons\u003cbr\u003e\u003cstrong\u003eTemperament:\u003c\/strong\u003e Peaceful\u003cbr\u003e\u003cstrong\u003eDiet:\u003c\/strong\u003e Planktivore \/ Omnivore\u003cbr\u003e\u003cstrong\u003eReef Safe:\u003c\/strong\u003e Yes\u003cbr\u003e\u003cstrong\u003eRegion:\u003c\/strong\u003e Indo-West Pacific\u003cbr\u003e\u003cstrong\u003eScientific Name:\u003c\/strong\u003e \u003cem\u003eGenicanthus lamarck\u003c\/em\u003e\u003c\/p\u003e\n\u003ch2\u003eTank Requirements\u003c\/h2\u003e\n\u003cp\u003eThe Lamarck Angelfish is an active open-water swimmer and should be provided with a mature aquarium of at least 125 gallons. Adults can approach approximately 10 inches in total length, so long-term housing should prioritize horizontal swimming room rather than filling the aquarium entirely with rockwork.\u003c\/p\u003e\n\u003cp\u003eProvide substantial live rock around the sides and back of the aquarium, leaving broad areas of open water for cruising. Caves, overhangs, and crevices give the fish secure retreat areas during acclimation and at night. A well-established aquarium is preferred, particularly because mature rockwork provides additional natural feeding opportunities and a more stable environment.\u003c\/p\u003e\n\u003cp\u003eModerate to strong water movement, good oxygenation, efficient filtration, and consistent water quality are ideal. Because this species spends much of its time swimming in the water column, an aquarium layout that combines reef structure with generous open space will best accommodate its natural behavior.\u003c\/p\u003e\n\u003ch2\u003eDiet and Feeding\u003c\/h2\u003e\n\u003cp\u003eLamarck Angelfish are primarily planktivorous in the wild, feeding on suspended plankton above the reef. In captivity, they adapt well to a varied marine diet and should receive several different food types to maintain body condition and coloration.\u003c\/p\u003e\n\u003cp\u003eOffer mysis shrimp, enriched brine shrimp, finely chopped marine seafood, copepod-based foods, quality frozen marine blends, small sinking or slow-sinking pellets, and appropriately sized flakes. Spirulina and other marine algae-based foods can also be included for additional nutritional variety.\u003c\/p\u003e\n\u003cp\u003eTwo to three smaller feedings per day are preferable when possible, especially for newly introduced specimens accustomed to feeding repeatedly on plankton throughout the day.\u003c\/p\u003e\n\u003ch2\u003eTemperament and Tankmates\u003c\/h2\u003e\n\u003cp\u003eThe female Lamarck Angelfish is generally peaceful and considerably less territorial than many \u003cem\u003ePomacanthus\u003c\/em\u003e or \u003cem\u003eHolacanthus\u003c\/em\u003e angelfish. It is well suited to community aquariums containing peaceful to moderately assertive marine fish such as tangs, wrasses, anthias, gobies, blennies, rabbitfish, and other compatible reef species.\u003c\/p\u003e\n\u003cp\u003eIt may be maintained singly or, in appropriately sized aquariums, as part of a compatible pair or harem consisting of one male with multiple females. Avoid keeping multiple established males together unless the aquarium is exceptionally large and carefully managed.\u003c\/p\u003e\n\u003cp\u003eLike other \u003cem\u003eGenicanthus\u003c\/em\u003e angelfish, Lamarck Angelfish have a socially influenced sex structure. Females are capable of transitioning toward male coloration and sex when social conditions favor the change, which is worth considering when planning pairs or groups.\u003c\/p\u003e\n\u003ch2\u003eReef Compatibility\u003c\/h2\u003e\n\u003cp\u003eThe Lamarck Angelfish is considered \u003cstrong\u003ereef safe\u003c\/strong\u003e and is one of the better angelfish choices for coral-dominated aquariums.\u003c\/p\u003e\n\u003cp\u003eBecause its natural feeding strategy focuses heavily on plankton captured in the water column, it is much less inclined to graze directly on corals than many other marine angelfish. It is generally compatible with SPS and LPS corals, soft corals, zoanthids, clams, and most ornamental invertebrates.\u003c\/p\u003e\n\u003cp\u003eAs with virtually any individual fish, occasional investigative picking is possible, but persistent coral predation is not considered typical behavior for this species.\u003c\/p\u003e\n\u003ch2\u003eWater Parameters\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eTemperature:\u003c\/strong\u003e 75–80°F\u003cbr\u003e\u003cstrong\u003eSpecific Gravity:\u003c\/strong\u003e 1.024–1.026\u003cbr\u003e\u003cstrong\u003epH:\u003c\/strong\u003e 8.1–8.4\u003cbr\u003e\u003cstrong\u003eAlkalinity:\u003c\/strong\u003e 8–12 dKH\u003c\/p\u003e\n\u003cp\u003eStable water chemistry, strong oxygenation, and consistently good water quality are more important than maintaining one exact number within these ranges.
