Cycloseris fragilis | L

Cycloseris fragilis is a captivating large polyp stony (LPS) coral from the Fungiidae family, prized for its distinctive free-living, disc-like form and vibrant colours. This species is a fascinating addition to mature reef aquariums, offering both visual appeal and interesting behaviour as it can move slightly across the substrate.

Care Level: Moderate to advanced. Cycloseris fragilis requires stable water parameters and attentive husbandry to thrive.

Lighting: Moderate lighting is recommended. Too intense lighting may cause bleaching, while too low light can reduce growth and colour vibrancy. LED or T5 lighting systems with adjustable intensity work well.

Water Flow: Moderate, indirect water flow is ideal. Strong currents can damage the delicate tissue, while stagnant water may promote detritus accumulation.

Placement: Place Cycloseris fragilis on sandy or fine rubble substrate where it can rest freely. Ensure adequate spacing from neighbouring corals to prevent aggressive interactions, as it can extend sweeper tentacles.

Diet: Primarily photosynthetic via symbiotic zooxanthellae, but benefits from supplemental feeding of meaty foods such as mysis shrimp, brine shrimp, or specialised coral foods 1-2 times per week.

Reef Compatibility: Yes, with adequate spacing. This coral is generally reef safe but can be aggressive towards nearby corals due to sweeper tentacles.

Origin: Not Provided.

Maximum Size: Up to 15 cm in diameter.

Minimum Tank Size: 90 litres (20 gallons) or larger to provide stable conditions and space for growth.

Regular monitoring of water quality, including calcium, alkalinity, and magnesium, is essential to maintain skeletal growth and overall health. Avoid rapid changes in lighting or water parameters to reduce stress.
