{"product_id":"checkerboard-wrasse-halichoeres-hortulanus","title":"Checkerboard Wrasse (Halichoeres hortulanus)","description":"\u003cp\u003eThe Checkerboard Wrasse is one of the most visually striking members of a genus full of outstanding fish. Adult males carry a silvery white body overlaid with a bold black checkerboard pattern, a light green face with orange to pink striped markings, and a vivid yellow dorsal fin and tail, while the eyes shift from yellow to a brilliant red depending on the individual. But beyond its looks, this wrasse earns serious points for utility. The Checkerboard Wrasse is sought after for its incredible natural ability to control and eliminate nuisance red planaria flatworms and pyramidellid snails that sometimes hitchhike on corals or live rock, making it one of the most practically useful additions to any established reef system. Active, hardy, and full of personality, this is a wrasse that works as hard as it looks good.\u003c\/p\u003e\n\u003ch3\u003eWhy we love it\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eStunning adult colouration with bold checkerboard patterning, green face, and yellow fins\u003c\/li\u003e\n\u003cli\u003eNatural flatworm and pyramidellid snail predator that provides genuine pest control in reef systems\u003c\/li\u003e\n\u003cli\u003eAlso known to actively hunt and consume nuisance pyramid snails and planaria flatworms\u003c\/li\u003e\n\u003cli\u003eHardy, adaptable, and an eager feeder once settled\u003c\/li\u003e\n\u003cli\u003eFascinating life history with dramatic colour and pattern changes from juvenile to adult\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSuggested parameters\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTemperature: 24 to 26°C (75 to 79°F)\u003c\/li\u003e\n\u003cli\u003eSalinity: 1.025 to 1.026 SG\u003c\/li\u003e\n\u003cli\u003epH: 8.1 to 8.4\u003c\/li\u003e\n\u003cli\u003eAlkalinity: 8 to 10 dKH\u003c\/li\u003e\n\u003cli\u003eCalcium: 400 to 450 ppm\u003c\/li\u003e\n\u003cli\u003eMagnesium: 1250 to 1400 ppm\u003c\/li\u003e\n\u003cli\u003eNitrate: 5 to 20 ppm\u003c\/li\u003e\n\u003cli\u003ePhosphate: 0.03 to 0.12 ppm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCare and temperament\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDifficulty: Easy to moderate\u003c\/li\u003e\n\u003cli\u003eTemperament: Peaceful toward most fish; can be territorial toward conspecifics and similar-looking wrasses in smaller systems\u003c\/li\u003e\n\u003cli\u003eReef safe: With caution (will consume snails, tubeworms, small crustaceans, sea stars, and urchins; as it grows into adulthood it may also target smaller fish by bashing them against hard surfaces before consuming; ornamental shrimp and small decorative inverts are at risk)\u003c\/li\u003e\n\u003cli\u003eMinimum tank size: 90 to 100 gallons\u003c\/li\u003e\n\u003cli\u003eRequires a minimum 3 inch sandbed; newly introduced wrasses will often dive straight into the substrate upon release and will use it nightly for sleep and as a refuge when startled\u003c\/li\u003e\n\u003cli\u003eA fine sand bed of 0.5 to 2.0 mm grain size at least 4 inches deep is ideal, along with rocky crevices for hunting and open swimming areas\u003c\/li\u003e\n\u003cli\u003eA tight-fitting lid is essential; this species will jump\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eDiet\u003c\/h3\u003e\n\u003cp\u003eThe Checkerboard Wrasse is a dedicated carnivore and active hunter throughout the day.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFrozen mysis shrimp (staple)\u003c\/li\u003e\n\u003cli\u003eFrozen brine shrimp and enriched artemia\u003c\/li\u003e\n\u003cli\u003eMixed meaty frozen foods including small crustacean blends\u003c\/li\u003e\n\u003cli\u003eQuality carnivore pellets once trained\u003c\/li\u003e\n\u003cli\u003eSoaking frozen foods in vitamin and fatty acid supplements is encouraged, as these wrasses have very high metabolisms\u003c\/li\u003e\n\u003cli\u003eSmall pieces of rock placed in the aquarium give the wrasse objects to interact with and investigate during its daily hunt\u003c\/li\u003e\n\u003cli\u003eMultiple small feedings per day; this species grazes actively throughout the daylight hours\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompatibility and tankmates\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eGood with clownfish, tangs, angelfish, gobies, dartfish, and most medium to large peaceful reef community fish\u003c\/li\u003e\n\u003cli\u003eCompatible with other peaceful wrasses including different \u003cem\u003eHalichoeres\u003c\/em\u003e species; best to introduce all wrasses simultaneously for the smoothest outcome\u003c\/li\u003e\n\u003cli\u003eKeep one male per system; a harem of one male and a couple of females can cohabitate well if introduced at the same time\u003c\/li\u003e\n\u003cli\u003eCaution is advised with small ornamental crustaceans, feather dusters, and very small fish as these may be hunted\u003c\/li\u003e\n\u003cli\u003eAvoid housing with very small fish such as neon gobies or small dartfish that may be mistaken for prey as the wrasse grows\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHealth and acclimation notes\u003c\/h3\u003e\n\u003cp\u003eThe Checkerboard Wrasse is one of the hardier \u003cem\u003eHalichoeres\u003c\/em\u003e species and settles into aquarium life readily given the right setup. The sandbed is non-negotiable; without sufficient substrate depth this wrasse cannot sleep or take refuge properly, and stress levels will be chronically elevated. It is very common for a newly introduced wrasse to immediately bury itself upon release; this is completely normal and the fish will typically emerge and begin exploring within hours to a day or two. Care should be taken when sourcing this species to ensure it was not injured around the mouth during transport, as mouth injuries are a common issue with wrasses.\u003c\/p\u003e\n\u003ch3\u003eWhat you are buying\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eYou will receive: 1 Checkerboard Wrasse (Halichoeres hortulanus)\u003c\/li\u003e\n\u003cli\u003eJuveniles have a predominantly white body mottled in brown; the namesake checkerboard pattern develops clearly with maturity\u003c\/li\u003e\n\u003cli\u003eColour and pattern vary depending on age, collection area, and breeding condition\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA tight-fitting lid is essential, as this species will jump.
