Its unusual appearance makes it an eye-catching display animal, but unlike many reef-safe starfish it is an opportunistic feeder that may consume corals, sponges and other sessile invertebrates. For this reason, it is best suited to fish-only or carefully planned marine aquariums rather than delicate reef systems.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eCommon Name:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eRed Knobbed Starfish, Red-Knobbed Sea Star, African Red Knob Starfish\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eScientific Name (Latin):\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eProtoreaster lincki\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eMaximum Size:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eApproximately 30 cm\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eWater Type:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eMarine\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eOrigin \/ Natural Habitat:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eThe Red Knobbed Starfish occurs throughout tropical Indo-Pacific marine environments and is commonly associated with shallow lagoons, sandy reef flats, rubble zones and sheltered coastal habitats.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eIt spends much of its time moving slowly across sand, rock and other bottom surfaces while searching for food.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003e\u003cstrong\u003eWater Parameters\u003c\/strong\u003e:\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eTemperature: 24–26°C\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003epH Range: 8.1–8.4\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eSalinity: SG 1.024–1.026\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eNitrate: Low and stable\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eCopper: Must be avoided\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003e\u003cstrong\u003eTemperament\u003c\/strong\u003e:\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003ePeaceful\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eRed Knobbed Starfish are peaceful towards fish and do not display territorial behaviour.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eTheir main compatibility concern is feeding, as they are opportunistic and may consume a wide range of sessile reef organisms.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003e\u003cstrong\u003eDiet\u003c\/strong\u003e:\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eOmnivore \/ Scavenger\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThe Red Knobbed Starfish feeds on detritus, carrion and a variety of benthic organisms.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eIn the aquarium, offer suitably sized pieces of prawn, mussel, cockle, clam, squid and other marine-based foods.
