{"product_id":"humu-triggerfish-rhinecanthus-aculeatus","title":"Humu Triggerfish | Rhinecanthus aculeatus","description":"\u003ch2\u003eDescription\u003c\/h2\u003e\u003cp\u003eThe famous Picasso trigger, the Humu wears a face full of bold lines and a personality to match. A hardy, characterful fish for a fish-only tank with room and confident neighbours.\u003c\/p\u003e\u003ch2\u003eNatural Habitat\u003c\/h2\u003e\u003cp\u003eMost triggerfish live around reef slopes, rubble zones and coral edges where they cruise actively, investigate rockwork and feed on hard-shelled invertebrates or meaty foods. Natural origin for this listing is Indo-Pacific reef slopes, lagoons, rubble zones and coral reef edges depending on species. In captivity, the aquarium should recreate the security of reef structure with caves, ledges, open turning space and excellent filtration. These fish produce more waste than small community species, so oxygenation, protein skimming and stable water quality are critical.\u003c\/p\u003e\u003ch2\u003eAppearance\u003c\/h2\u003e\u003cp\u003eHumu Triggerfish should show clear eyes, full body condition, intact fins and a strong feeding response. Triggerfish have a deep, muscular body, tough skin, strong teeth and the distinctive dorsal trigger spine that gives the group its name. Adult size is generally 25–30 cm, so the fish should never be purchased only for its current size. Colour, pattern and behaviour are usually best displayed once the fish has a secure territory and is feeding confidently.\u003c\/p\u003e\u003ch2\u003eTemperament and Compatibility\u003c\/h2\u003e\u003cp\u003eTemperament is best described as Bold, intelligent and semi-aggressive to aggressive. Compatibility must be planned carefully. Suitable tank mates are generally robust marine fish that are too large to be swallowed and confident enough to feed, such as larger tangs, rabbitfish, large wrasse, robust angelfish, suitable triggers, groupers or other predators depending on the species. Avoid tiny fish, small ornamental shrimp, delicate timid species and anything that can fit into the mouth. For triggerfish and larger predators, also consider biting behaviour, rock movement and aggression at feeding time.\u003c\/p\u003e\u003ch2\u003eFeeding\u003c\/h2\u003e\u003cp\u003eFeed as an Omnivore to carnivore; chopped prawn, squid, mussel, clam, krill, mysis shrimp, quality pellets and occasional algae-based foods. Use marine-based foods rather than freshwater feeder fish, as freshwater feeders are poor long-term nutrition and can contribute to health problems. Offer appropriately sized portions several times weekly or daily depending on the species, age and body condition. Predatory fish should be trained to accept frozen or prepared foods where possible. Feeding tongs are useful for eels, lionfish and scorpionfish, but hands should be kept away from mouths and venomous spines.\u003c\/p\u003e\u003ch2\u003eCare Requirements\u003c\/h2\u003e\u003cp\u003eMinimum aquarium size is 450 L, with 650 L or larger recommended for long-term care. Maintain temperature at 24–27°C, pH 8.1–8.4 and salinity 1.024–1.026. Provide strong biological filtration, quality protein skimming and regular water changes of 10–20% as required to control nitrate and phosphate. Flow should provide good oxygenation without preventing the fish from resting. Lighting can match the system and is usually not critical for the fish itself. Aquascaping must be stable, with secure rockwork that cannot collapse if a triggerfish, eel or large predator pushes through it. Eels require a tight lid with no gaps.\u003c\/p\u003e\u003ch2\u003eBreeding\u003c\/h2\u003e\u003cp\u003eBreeding is not expected in normal aquariums. Wild triggerfish may guard nests aggressively, and larval rearing is not practical for most hobbyists. In home aquariums, breeding should not be expected. Many of these species have complex courtship, pelagic eggs or larvae, large adult size or specialist rearing needs. The practical focus should be correct feeding, stable water quality, secure housing and careful tank mate selection.\u003c\/p\u003e\u003ch2\u003eSpecies Information\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eScientific Name\u003c\/td\u003e\n\u003ctd\u003eRhinecanthus aculeatus\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Name\u003c\/td\u003e\n\u003ctd\u003eHumu Triggerfish\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eIndo-Pacific reef slopes, lagoons, rubble zones and coral reef edges depending on species\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Size\u003c\/td\u003e\n\u003ctd\u003e25–30 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLifespan\u003c\/td\u003e\n\u003ctd\u003e8–15 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperament\u003c\/td\u003e\n\u003ctd\u003eBold, intelligent and semi-aggressive to aggressive\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDifficulty\u003c\/td\u003e\n\u003ctd\u003eIntermediate to advanced\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Tank Size\u003c\/td\u003e\n\u003ctd\u003e450 L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Tank Size\u003c\/td\u003e\n\u003ctd\u003e650 L or larger\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiet\u003c\/td\u003e\n\u003ctd\u003eOmnivore to carnivore; chopped prawn, squid, mussel, clam, krill, mysis shrimp, quality pellets and occasional algae-based foods\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater Temperature\u003c\/td\u003e\n\u003ctd\u003e24–27°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003epH Range\u003c\/td\u003e\n\u003ctd\u003e8.1–8.4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGH Range\u003c\/td\u003e\n\u003ctd\u003eNot applicable for marine aquariums\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSalinity\u003c\/td\u003e\n\u003ctd\u003e1.024–1.026\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSuitable For\u003c\/td\u003e\n\u003ctd\u003eLarge marine aquariums, predator systems and specialist fish-only displays\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReef Safe\u003c\/td\u003e\n\u003ctd\u003eReef safe with caution to not reef safe; may bite corals, move rockwork or eat invertebrates depending on species\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePlant Safe\u003c\/td\u003e\n\u003ctd\u003eNot applicable for marine aquariums\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eSuitable Tank Mates\u003c\/h2\u003e\u003cp\u003eSuitable tank mates may include larger tangs, rabbitfish, robust wrasse, large angelfish with caution, larger clownfish, suitable triggers, groupers, larger hawkfish and other predator-safe marine fish.
