{"product_id":"scribbled-rabbitfish","title":"Scribbled Rabbitfish | Siganus spinus","description":"\u003ch2\u003eDescription\u003c\/h2\u003e\u003cp\u003eThe Scribbled Rabbitfish is a hardy, algae-grazing reef fish patterned with fine wavy lines across a silvery body. Reaching around 25–28 cm, it makes an excellent natural clean-up crew member, working tirelessly over the rockwork. Handle with care, as the dorsal and anal spines are venomous and can deliver a painful sting.\u003c\/p\u003e\u003ch2\u003eNatural Habitat\u003c\/h2\u003e\u003cp\u003eSiganus spinus occurs across the western Pacific and eastern Indian Ocean, often in shallow reef flats, seagrass beds and lagoons where algae is abundant. Juveniles frequently form schools in weedy shallows, moving onto the reef as they mature. In the aquarium it appreciates plenty of live rock for grazing, open water for swimming and stable, well-oxygenated conditions. It suits both reef and fish-only systems that have room for an active, medium-sized grazer.\u003c\/p\u003e\u003ch2\u003eAppearance\u003c\/h2\u003e\u003cp\u003eThe body is deep and laterally compressed, silvery to brownish, and covered in the intricate scribbled lines that give the species its name. Fins are largely translucent, and when alarmed the fish can display a mottled camouflage pattern. Its most important feature to remember is the set of sharp, venomous fin spines. Healthy fish are alert, full-bodied and graze actively throughout the day.\u003c\/p\u003e\u003ch2\u003eTemperament and Compatibility\u003c\/h2\u003e\u003cp\u003eThis is a generally peaceful fish that mixes well in a busy community, though it can become mildly territorial with other rabbitfish. Its venomous spines mean it is largely left alone by other fish and should be netted or handled with great care by the keeper. It combines well with tangs, wrasses, angelfish, clownfish and other robust reef fish. Give it space and it will spend its days peacefully grazing.\u003c\/p\u003e\u003ch2\u003eFeeding\u003c\/h2\u003e\u003cp\u003eA dedicated herbivore, the Scribbled Rabbitfish should be offered a diet rich in marine algae: dried nori, spirulina and prepared herbivore foods, supplemented with occasional meaty items such as mysis. Frequent small feedings suit its constant grazing habit, and a good supply of algae on the rockwork helps keep it occupied and healthy. A varied vegetable-based diet keeps colours strong and the fish in good condition.\u003c\/p\u003e\u003ch2\u003eCare Requirements\u003c\/h2\u003e\u003cp\u003eProvide a minimum aquarium of 250 L, with 400 L or more recommended for long-term comfort and swimming room. Maintain 24–27°C, pH 8.1–8.4 and salinity around 1.020–1.026. Good water movement, efficient filtration and regular water changes suit this active grazer. Take particular care when catching or moving the fish, as the venomous spines can inflict a painful sting.\u003c\/p\u003e\u003ch2\u003eBreeding\u003c\/h2\u003e\u003cp\u003eRabbitfish are open-water spawners that release eggs and sperm into the water column, and the larvae are planktonic. Captive breeding is not practical in the home aquarium, as raising the tiny larvae requires specialised planktonic foods and dedicated systems. For hobbyists the focus should be on good grazing, stable water and safe handling rather than breeding.\u003c\/p\u003e\u003ch2\u003eSpecies Information\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eScientific Name\u003c\/td\u003e\n\u003ctd\u003eSiganus spinus\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Name\u003c\/td\u003e\n\u003ctd\u003eScribbled Rabbitfish (Little Spinefoot)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eIndo-West Pacific reef flats, lagoons and seagrass beds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Size\u003c\/td\u003e\n\u003ctd\u003e28 cm (typically around 18–25 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLifespan\u003c\/td\u003e\n\u003ctd\u003e8–10 years with good care\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperament\u003c\/td\u003e\n\u003ctd\u003ePeaceful (venomous spines)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDifficulty\u003c\/td\u003e\n\u003ctd\u003eIntermediate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Tank Size\u003c\/td\u003e\n\u003ctd\u003e250 L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Tank Size\u003c\/td\u003e\n\u003ctd\u003e400 L or larger\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiet\u003c\/td\u003e\n\u003ctd\u003eHerbivore; marine algae, nori and prepared greens\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 fish\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSalinity\u003c\/td\u003e\n\u003ctd\u003e1.020–1.026\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSuitable For\u003c\/td\u003e\n\u003ctd\u003eReef and fish-only systems with grazing room\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReef Safe\u003c\/td\u003e\n\u003ctd\u003eReef safe with caution (may occasionally nip corals if underfed)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePlant Safe\u003c\/td\u003e\n\u003ctd\u003eNot applicable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eSuitable Tank Mates\u003c\/h2\u003e\u003cp\u003eSuitable tank mates include tangs, larger wrasses, angelfish, clownfish, damselfish and other robust reef fish of similar size that appreciate the same conditions.\u003c\/p\u003e\u003ch2\u003eAvoid Keeping With\u003c\/h2\u003e\u003cp\u003eAvoid keeping with other rabbitfish in smaller tanks, as well as very aggressive predators that may harass it.
