{"product_id":"bicolour-anthias-extra","title":"Bicolour Anthias Extra | Nemanthias bicolor","description":"\u003ch2\u003eDescription\u003c\/h2\u003e\u003cp\u003eThe Bicolour Anthias is a shimmering, open-water anthias with a purple-to-magenta back and a bright yellow lower body, bringing constant movement and colour to a peaceful reef. It is one of the more manageable anthias, but like all of the group it needs frequent small feeds and a settled tank to thrive.\u003c\/p\u003e\u003ch2\u003eNatural Habitat\u003c\/h2\u003e\u003cp\u003eIn the wild, the Bicolour Anthias is associated with deeper reef slopes and drop-offs of the Indo-Pacific, where it hovers in loose groups picking zooplankton from the current. It spends the day in mid-water, retreating into the rockwork when startled. Replicating this environment means providing open swimming space above the reef, branching rockwork with caves and overhangs, and moderate to strong flow that keeps food suspended in the water column.\u003c\/p\u003e\u003ch2\u003eAppearance\u003c\/h2\u003e\u003cp\u003eThe Bicolour Anthias has a violet to magenta upper body and a yellow lower body and tail, with the slender, agile shape typical of reef planktivores. It reaches around 13 cm, though most stay smaller in captivity. Colour intensifies with good nutrition, stable water and appropriate social structure, and dominant males are the most vividly coloured. Healthy specimens are alert, actively picking at the water column, well-filled and feeding confidently, without pinched bellies or laboured breathing.\u003c\/p\u003e\u003ch2\u003eTemperament and Compatibility\u003c\/h2\u003e\u003cp\u003eTemperament is best described as peaceful. It is a good reef community fish and is safe with corals and ornamental invertebrates. Suitable companions include clownfish, gobies, blennies, dartfish, chromis, fairy and flasher wrasses, peaceful tangs and other calm reef fish. Avoid aggressive fish that will intimidate it or outcompete it at feeding time. It can be kept singly or, in a larger aquarium, as a group with one dominant male, which shows the best colour and behaviour.\u003c\/p\u003e\u003ch2\u003eFeeding\u003c\/h2\u003e\u003cp\u003eAnthias have fast metabolisms and need frequent small feeds. Offer several small meals a day of mysis shrimp, enriched brine shrimp, copepods, finely chopped seafood, frozen plankton blends and quality marine pellets once accepted. Automatic feeding with small pellets can help maintain condition through the day. Newly introduced specimens often prefer frozen foods first, then accept pellets. Frequent, varied feeding is the key to strong colour, good body weight and long-term success.\u003c\/p\u003e\u003ch2\u003eCare Requirements\u003c\/h2\u003e\u003cp\u003eFor long-term success, provide a minimum aquarium size of 200 L for a single fish, with 400 L or larger recommended for a group and long-term stability. Maintain temperature at 24–26°C, pH 8.1–8.4 and salinity around 1.020–1.026. Provide moderate to strong, varied flow so food stays suspended. Lighting can be standard reef lighting, with shaded retreats available. Use strong biological filtration, a quality protein skimmer and regular water changes of 10–20% to keep nitrate and phosphate controlled. Provide rockwork with caves and overhangs plus open swimming space. Introduce timid anthias before more aggressive tank mates where possible.\u003c\/p\u003e\u003ch2\u003eBreeding\u003c\/h2\u003e\u003cp\u003eAnthias are protogynous hermaphrodites, so females can change into males when social conditions allow. Courtship and displaying may be seen in a stable, well-fed group, but raising larvae is very difficult and generally beyond standard home breeding. Stable groups, frequent feeding and excellent water quality are needed before spawning behaviour is likely. For most keepers the goal is a healthy, colourful fish or group rather than captive reproduction.\u003c\/p\u003e\u003ch2\u003eSpecies Information\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eScientific Name\u003c\/td\u003e\n\u003ctd\u003eNemanthias bicolor (syn.
