Females typically show a larger yellow region than mature males and lack some of the intensified magenta coloration and elongated fin development associated with dominant males. Their bright coloration and constant midwater activity make them especially attractive in illuminated reef aquariums.\u003c\/p\u003e\n\u003cp\u003eThis Marshall Islands form originates from the central Pacific portion of the species’ natural range, where Bartlett’s Anthias occur around reef slopes in aggregations composed primarily of females and juveniles with comparatively few males. They spend much of the day swimming above reef structure and capturing small zooplankton carried through the water column.\u003c\/p\u003e\n\u003cp\u003eThe female Bartlett’s Anthias is an excellent marine aquarium fish for established reef aquariums and appropriately stocked fish-only systems. Although generally compatible with peaceful community fish, Bartlett’s Anthias establish a social hierarchy among themselves, and females have the ability to transition into males when social conditions favor the change.\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 70 gallons\u003cbr\u003e\u003cstrong\u003eTemperament:\u003c\/strong\u003e Semi-aggressive\u003cbr\u003e\u003cstrong\u003eDiet:\u003c\/strong\u003e Carnivore \/ Planktivore\u003cbr\u003e\u003cstrong\u003eReef Safe:\u003c\/strong\u003e Yes\u003cbr\u003e\u003cstrong\u003eRegion:\u003c\/strong\u003e Marshall Islands – Central Pacific\u003cbr\u003e\u003cstrong\u003eScientific Name:\u003c\/strong\u003e \u003cem\u003eNemanthias bartlettorum\u003c\/em\u003e\u003c\/p\u003e\n\u003ch2\u003eTank Requirements\u003c\/h2\u003e\n\u003cp\u003eProvide a mature marine aquarium with generous open swimming space above and around the rockwork. Bartlett’s Anthias are active water-column swimmers and should not be confined to densely packed aquascapes with limited room to move.\u003c\/p\u003e\n\u003cp\u003eLive rock should provide multiple caves, ledges, and shaded retreats where the fish can shelter at night or escape unwanted attention from tankmates. Numerous retreat areas become especially important when maintaining several anthias together.\u003c\/p\u003e\n\u003cp\u003eModerate to strong, well-distributed water movement is appropriate and helps replicate the current-swept reef environments where these fish naturally feed. Strong oxygenation and efficient filtration are also beneficial because the frequent feeding required by anthias can increase nutrient input.\u003c\/p\u003e\n\u003cp\u003eA securely fitted mesh screen or aquarium lid is recommended, as anthias may jump when startled or chased.\u003c\/p\u003e\n\u003ch2\u003eDiet and Feeding\u003c\/h2\u003e\n\u003cp\u003eBartlett’s Anthias are carnivorous planktivores that naturally feed on zooplankton and small crustaceans suspended in the water column.\u003c\/p\u003e\n\u003cp\u003eOffer a varied captive diet consisting of enriched mysis shrimp, enriched brine shrimp, copepods, frozen plankton, finely chopped marine seafood, quality frozen reef blends, and appropriately sized marine pellets or flakes. Foods that remain suspended in the water column encourage natural feeding behavior.\u003c\/p\u003e\n\u003cp\u003eTwo to three small feedings per day are recommended, with additional small meals beneficial when practical. Newly introduced females may respond especially well to copepods, mysis, and other small frozen foods while becoming accustomed to prepared diets.\u003c\/p\u003e\n\u003ch2\u003eTemperament and Tankmates\u003c\/h2\u003e\n\u003cp\u003eFemale Bartlett’s Anthias are generally peaceful toward unrelated community fish but can become assertive with other anthias as a social hierarchy develops. Dominant individuals may chase subordinate females, particularly when aquarium space or hiding areas are limited.\u003c\/p\u003e\n\u003cp\u003eSuitable tankmates include clownfish, gobies, blennies, fairy and flasher wrasses, tangs, peaceful angelfish, and other non-predatory marine fish. Avoid highly aggressive species that may intimidate the anthias or prevent it from feeding regularly.\u003c\/p\u003e\n\u003cp\u003eA single female can be maintained successfully. Groups can also be kept in larger aquariums with ample swimming room and numerous retreats, but social interactions should be monitored carefully. In the absence of a dominant male, one female may begin transitioning into a male. Occasionally, multiple females may begin transitioning, which can result in increased aggression.\u003c\/p\u003e\n\u003ch2\u003eReef Compatibility\u003c\/h2\u003e\n\u003cp\u003eThe female Bartlett’s Anthias is considered reef safe and is an excellent choice for coral-dominated aquariums. It does not normally consume or damage stony corals, soft corals, clams, or other sessile reef organisms.\u003c\/p\u003e\n\u003cp\u003eIt is also generally compatible with ornamental shrimp, crabs, snails, and other common reef invertebrates. Tiny copepods and other planktonic crustaceans may naturally be consumed as part of its normal feeding behavior.\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\u003eMaintain stable, well-oxygenated water with consistently good water quality.
