Fiji Multicolor Zoanthid (Zoanthus sp.)
Fiji Multicolor Zoanthid (Zoanthus sp.)
The Fiji Multicolor Zoanthid is a vibrant soft coral featuring a dense cluster of polyps that display rich green, yellow, red, and orange tones. Under blue-spectrum aquarium lighting, these contrasting colors fluoresce brilliantly to create a dynamic visual display on your reef rockwork.
As an encrusting colonial species, it thrives under low-to-moderate water flow and lighting while gradually expanding across open structure. Hardy and photosynthetic, this established WYSIWYG specimen makes an adaptable, colorful addition to established saltwater reef aquariums.

Materials & care
- Diet: Mixotroph. Primarily photosynthetic but also capable of absorbing dissolved nutrients and capturing very fine suspended foods.
- Feeding: Supplemental feeding is optional. Fine particulate coral foods, finely crushed marine foods, or other appropriately sized zooplankton-based foods may be offered approximately 1–2 times per week. Avoid excessive feeding, as zoanthids receive much of their nutritional needs through photosynthesis.
- Reef Compatibility: Reef Safe. Zoanthids are generally compatible with reef-safe fish and invertebrates but should be given sufficient room to spread as the colony grows.
- Spacing: Allow room around the colony for future growth. Zoanthids can gradually spread onto adjacent rockwork and may compete for space with neighboring corals.
- Temperament: Generally Peaceful, although their rapid encrusting growth can eventually bring them into competition with nearby corals.
- Placement: Suitable for lower-to-middle rockwork, depending on lighting intensity. Placement on an isolated rock can also help control the colony's spread as it grows.
- Water Flow: Low to Moderate. Enough flow should be provided to keep debris from settling between the polyps while still allowing the colony to remain fully extended.
- Lighting: Low to Moderate reef lighting is generally suitable. Coloration can become particularly intense under blue-spectrum lighting. New colonies should be gradually acclimated to stronger lighting.
- Water Requirements: Maintain stable reef conditions with consistent temperature, salinity, alkalinity, and nutrient levels. Zoanthids are relatively adaptable but perform best when rapid parameter swings are avoided.
- Handling: Zoanthids should be handled carefully and preferably with gloves and eye protection. Some zoanthids can contain palytoxin or related toxins, so avoid contact with the eyes or mouth and thoroughly wash exposed skin after handling. Never boil or expose zoanthid-covered rock to hot water or steam.
Compatibility
Reef-safe and peaceful with marine fish and invertebrates. Provide adequate space on rockwork to prevent the colony from encrusting over neighboring corals.
How to use
Carefully acclimate the colony to your aquarium's water parameters and lighting. Place on lower-to-middle rockwork with low-to-moderate flow, using gloves and protective eyewear during handling.
