Palythoa grandis is a premium cultured soft coral frag prized for its robust growth and attractive appearance in marine reef aquariums. This species is known for its large polyps and vibrant colours, making it a popular choice among reef hobbyists seeking to add texture and movement to their coral displays.
Care Level: Suitable for beginner to intermediate aquarists due to its hardy nature and adaptability.
Lighting Requirements: Prefers moderate lighting conditions. LED or T5 lighting systems that provide a balanced spectrum are ideal to maintain healthy pigmentation and growth.
Water Flow: Moderate water flow is recommended to ensure adequate nutrient delivery and waste removal without causing polyp retraction.
Placement: Place the frag on stable rockwork in areas with moderate light and flow. Allow sufficient spacing from neighbouring corals to prevent aggressive interactions, as Palythoa species can exhibit territorial behaviour.
Diet: Primarily photosynthetic, deriving energy from symbiotic zooxanthellae. Supplementary feeding with fine particulate foods such as phytoplankton or coral-specific liquid foods can promote growth.
Reef Compatibility: Yes, with adequate spacing. While generally reef safe, Palythoa grandis can produce palytoxin, so handle with care and avoid contact with sensitive species.
Origin: Cultured (DJM Grown) – sustainably propagated in controlled aquaculture environments.
Maximum Size: Polyps can reach up to 5cm in diameter under optimal conditions.
Minimum Tank Size: 60 litres (approx. 15 gallons) to provide stable water parameters and space for growth.
As a cultured frag, this Palythoa grandis offers an excellent opportunity to enhance your reef tank with a premium, sustainably sourced soft coral. Regular water testing and stable parameters will ensure long-term health and vibrancy.
