{"product_id":"maze-angelfish","title":"Maze Angelfish","description":"\u003cp\u003eThe Maze Angelfish (\u003cem\u003eChaetodontoplus cephalareticulatus\u003c\/em\u003e), also called the Blue Maze Angelfish, earns its name from the fine blue lines that wind across its head. Follow those markings back from the face and they lengthen into blue stripes along the darker flanks. A juvenile looks quite different. Yellow and black dominate its early pattern, and the blue markings develop as the fish matures.\u003c\/p\u003e\n\u003cp\u003eThis western Pacific marine angelfish spends much of its day close to structure. In an established aquarium, it can move from a shaded ledge to an exposed rock face, pause to pick at the surface, then circle back through cover. An aquascape that allows the fish to complete that circuit gives it places to graze and lets it withdraw when a tankmate approaches.\u003c\/p\u003e\n\u003cp\u003ePlan its home around an adult that may reach approximately 11 inches (28 cm). A mature, spacious marine display with established rockwork suits this species well. Its habit of investigating attached organisms deserves particular consideration when choosing between a fish-only display and an aquarium stocked with corals or ornamental clams.\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 for one adult\u003cbr\u003e\u003cstrong\u003eAdult Size:\u003c\/strong\u003e Up to approximately 11 inches (28 cm)\u003cbr\u003e\u003cstrong\u003eTemperament:\u003c\/strong\u003e Semi-aggressive\u003cbr\u003e\u003cstrong\u003eDiet:\u003c\/strong\u003e Omnivore\u003cbr\u003e\u003cstrong\u003eReef Safe:\u003c\/strong\u003e With caution\u003cbr\u003e\u003cstrong\u003eRegion:\u003c\/strong\u003e Western Pacific, including East Asian waters\u003cbr\u003e\u003cstrong\u003eScientific Name:\u003c\/strong\u003e \u003cem\u003eChaetodontoplus cephalareticulatus\u003c\/em\u003e\u003c\/p\u003e\n\u003ch2\u003eTank Requirements\u003c\/h2\u003e\n\u003cp\u003eAllow at least \u003cstrong\u003e125 gallons\u003c\/strong\u003e for adult housing. Footprint matters because the fish needs room to turn around at the ends of its swimming route and pass between rock formations without brushing its sides. In a display shared with other large fish, allow additional room for each resident to establish a resting site and reach food.\u003c\/p\u003e\n\u003cp\u003eBuild stable rock islands with broad passages between them. Include at least one shaded retreat deep enough to conceal the entire fish, preferably with a second exit. Leave an open lane along the front or back of the display. A continuous rock wall can offer many small crevices yet leave an adult angelfish with few usable shelters.\u003c\/p\u003e\n\u003cp\u003eChoose a well-established aquarium with mature grazing surfaces. A newly cycled tank with bare rock may have adequate biological filtration but offers little to investigate between meals. Keep some rock faces accessible as corals grow, and check that the angelfish can still reach its preferred shelter without squeezing past a colony.\u003c\/p\u003e\n\u003cp\u003eProvide good surface agitation and varied circulation. Food should reach more than one part of the aquarium, including a quieter area near cover. Arrange pumps so the fish can rest out of direct flow, and leave access behind rockwork for removing uneaten food after feeding.\u003c\/p\u003e\n\u003ch2\u003eDiet and Feeding\u003c\/h2\u003e\n\u003cp\u003eFeed a varied omnivorous diet in several small meals throughout the day. Grazing on established rock is valuable enrichment, but an angelfish can spend hours picking at surfaces without taking in enough food to maintain its weight. Look for the fish to approach food, take pieces into its mouth and swallow them.\u003c\/p\u003e\n\u003cp\u003eRotate foods with different textures and offer pieces small enough for the individual to swallow comfortably. Useful choices include:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFrozen marine angelfish preparations containing sponge\u003c\/li\u003e\n\u003cli\u003eMysis shrimp and finely chopped marine seafood\u003c\/li\u003e\n\u003cli\u003eMarine algae sheets secured to a clip close to the rockwork\u003c\/li\u003e\n\u003cli\u003eAlgae-based or omnivore marine pellets once the fish accepts prepared foods\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFor a shy arrival, release a small portion just outside its preferred cave while feeding bolder fish at the opposite end. If it investigates a sheet of algae but retreats whenever it swings in the current, secure the sheet closer to the rock. Remove leftovers before they break down and watch the abdomen over time for signs that the fish is losing condition.\u003c\/p\u003e\n\u003ch2\u003eTemperament and Tankmates\u003c\/h2\u003e\n\u003cp\u003eThe Maze Angelfish is semi-aggressive. It may share a large display with unrelated marine fish but defend a cave or grazing route against another deep-bodied angelfish. An otherwise quiet individual can become territorial after it settles in. Keeping one Maze Angelfish simplifies stocking in a display near the minimum recommended volume.\u003c\/p\u003e\n\u003cp\u003eChoose tankmates that can feed alongside the angelfish without repeatedly chasing it into cover. Established bullies can keep a new arrival from eating even when there is little visible damage to its fins. During introductions, watch from a distance through an entire feeding and check where the new fish settles when the lights dim.\u003c\/p\u003e\n\u003cp\u003eA brief display at a cave entrance is different from pursuit across the full length of the tank. If one fish consistently blocks both the shelter and the feeding area, add a visual barrier or separate the fish. Extra feeding points help only when each fish can reach one safely.\u003c\/p\u003e\n\u003ch2\u003eReef Compatibility\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eReef safe with caution.\u003c\/strong\u003e Maze Angelfish investigate surfaces with their mouths and may nip coral tissue or clam mantles. A fish-only aquarium with live rock allows this grazing behavior without placing prized colonies at risk. In a mixed reef, compatibility depends on the individual fish and the animals within its reach.\u003c\/p\u003e\n\u003cp\u003eWatch the same colony over several feeding and lighting cycles. A coral that closes briefly as the fish swims past may reopen quickly. Repeated attention to one patch of tissue, persistent polyp retraction or a clam that closes each time the fish approaches warrants closer observation. A varied diet supports the angelfish, but even a well-fed individual may continue to nip. Plan how you would separate the animals if that happens.\u003c\/p\u003e\n\u003ch2\u003eWater Parameters\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eTemperature:\u003c\/strong\u003e 75–78°F\u003cbr\u003e\u003cstrong\u003eSpecific Gravity:\u003c\/strong\u003e 1.024–1.025\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 well-oxygenated water with undetectable ammonia and nitrite. Several daily feedings can leave small amounts of food in crevices. Check those areas during maintenance, clean mechanical filtration regularly and follow nutrient trends as the angelfish grows.\u003c\/p\u003e\n\u003cp\u003eKeep temperature and salinity stable through the day. Check salinity with a calibrated instrument, especially after a water change or a top-off interruption. During transfers, use a suitably sized specimen container where practical because the angelfish’s cheek spines can catch in netting.\u003c\/p\u003e\n\u003ch2\u003eCommon Considerations\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cp\u003e\u003cstrong\u003eJuvenile coloration:\u003c\/strong\u003e Expect the yellow-and-black pattern to change as the blue adult markings develop.
