Native to the warm Caribbean, this peaceful species is recognized by its pearly white body covered in iridescent blue spots, bright yellow head, and expressive blue eyes. Unlike most reef fish, the Pearly Jawfish spends its days buildinh and maintaining its  burrow beneath the substrate, constantly rearranging shells, rubble, and sand. Hardy once established and full of character, the Pearly Jawfish is an excellent choice for reef keepers who can provide the deep substrate and peaceful environment it requires.\u003c\/p\u003e\n\u003ch2\u003eSuggested parameters\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eTemperature: \u003cstrong\u003e24–26°C (75–79°F)\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSalinity: \u003cstrong\u003e1.025–1.026 SG\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003epH: \u003cstrong\u003e8.1–8.4\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eAlkalinity: \u003cstrong\u003e8–10 dKH\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCalcium: \u003cstrong\u003e400–450 ppm\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eMagnesium: \u003cstrong\u003e1250–1400 ppm\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eNitrate: \u003cstrong\u003e2–20 ppm\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003ePhosphate: \u003cstrong\u003e0.03–0.10 ppm\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eCare and temperament\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eDifficulty:\u003c\/strong\u003e Moderate\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eTemperament:\u003c\/strong\u003e Peaceful\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eReef safe:\u003c\/strong\u003e Yes; completely reef safe with corals and ornamental invertebrates\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eMinimum tank size:\u003c\/strong\u003e 30 gallons (115 litres)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eRequires a fine sandy substrate at least \u003cstrong\u003e7–10 cm (3–4 inches)\u003c\/strong\u003e deep to construct a permanent burrow\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eProvide plenty of small pieces of rubble, crushed coral, and shells to reinforce and stabilize its burrow\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eBest kept in a mature aquarium with stable water parameters\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCan be shy initially but becomes increasingly confident once established\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eA tightly fitting lid is absolutely essential, as Pearly Jawfish are exceptional jumpers, especially when startled\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDiet\u003c\/h2\u003e\n\u003cp\u003eThe Pearly Jawfish is a carnivore that readily accepts a variety of meaty foods once settled into the aquarium.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eFrozen mysis shrimp\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eEnriched frozen brine shrimp\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eChopped krill\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eFinely chopped shrimp, clam, and other marine meaty foods\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCopepods and other small crustaceans\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eHigh-quality small marine pellets once acclimated\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eFeed 2–3 small meals daily for optimal health and body condition\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eCompatibility and tankmates\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eExcellent with clownfish, gobies, blennies, cardinalfish, firefish, fairy wrasses, flasher wrasses, anthias, and peaceful tangs\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSafe with corals, shrimp, snails, crabs, and other reef invertebrates\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eBest housed with peaceful fish that will not intimidate it around its burrow\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eAvoid aggressive dottybacks, large wrasses, triggerfish, puffers, lionfish, hawkfish, or other territorial predators\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eMultiple Pearly Jawfish can sometimes be kept together in larger aquariums if ample space and multiple burrow sites are available, but aggression may occur in smaller systems\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eHealth and acclimation notes\u003c\/h2\u003e\n\u003cp\u003eThe Pearly Jawfish adapts well when introduced into a mature aquarium with an appropriate sand bed. Slow drip acclimation over 45–60 minutes is recommended before release. It is completely normal for a newly introduced fish to disappear into its burrow for several days while becoming comfortable in its new surroundings. Avoid disturbing the sand around the burrow during this period. A secure lid should already be in place before introduction, as newly acclimating jawfish are especially prone to jumping. Offering small frozen foods near the burrow entrance encourages feeding and helps the fish settle more quickly.\u003c\/p\u003e\n\u003ch2\u003eWhat you are buying\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eYou will receive:\u003c\/strong\u003e 1 Pearly Jawfish \u003cem\u003e(Opistognathus aurifrons)\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003eColouration consists of a pearly white body decorated with iridescent blue spots, a vibrant yellow head, and striking blue facial markings.
