Rhodactis osculifera (Ultra)

Rhodactis osculifera (Ultra) is a large soft mushroom coral prized for its vivid colours and dynamic appearance in marine reef tanks. This coral belongs to the family Discosomatidae and is a popular choice for hobbyists seeking hardy, visually striking corals that add texture and movement to their reef aquariums.

Care Level: Moderate care requirements make this coral suitable for hobbyists with some experience in maintaining stable reef conditions.

Lighting: Prefers moderate lighting conditions. LED or T5 lighting systems that provide balanced PAR levels are ideal to maintain its vibrant colouration without causing bleaching.

Water Flow: Moderate, indirect water flow is recommended to ensure the coral’s delicate tissues are not damaged while promoting healthy gas exchange and nutrient delivery.

Placement: Place Rhodactis osculifera (Ultra) on rockwork or substrate where it can expand fully without being shaded by other corals. Provide adequate spacing to prevent aggressive interactions with neighbouring corals.

Diet: Primarily photosynthetic via symbiotic zooxanthellae but benefits from occasional feeding of microplankton or coral-specific liquid foods to support growth and colour vibrancy.

Reef Compatibility: Yes, with adequate spacing. This coral is generally peaceful but can extend sweeper tentacles, so maintain sufficient distance from other corals.

Minimum Tank Size: 60 litres (approximately 15 gallons) to ensure stable water parameters and adequate space for growth.

Origin: Not Provided.

Maximum Size: Large – typically reaching several centimetres in diameter when fully expanded.

With proper husbandry, Rhodactis osculifera (Ultra) can be a stunning and resilient addition to your marine reef aquarium, offering both aesthetic appeal and biological interest.
