Galaxea spp. are large polyp stony (LPS) corals known for their distinctive textured appearance and vibrant colours. Belonging to the family Oculinidae, these corals add both visual interest and complexity to mature reef aquariums.
Care Level: Moderate to advanced. Galaxea spp. require stable water parameters and attentive husbandry to thrive.
Lighting Requirements: Moderate to high lighting is recommended. LED or T5 lighting systems that provide a balanced spectrum will support healthy growth and vibrant pigmentation.
Water Flow: Moderate, indirect water flow is ideal. Too strong a current can cause tissue damage, while too little flow may lead to detritus accumulation.
Placement: Position Galaxea spp. on stable rockwork in the middle to lower regions of the aquarium. Ensure adequate spacing from neighbouring corals to prevent aggression, as this species can extend sweeper tentacles.
Diet: Primarily photosynthetic via symbiotic zooxanthellae, but benefit from supplemental feeding of meaty foods such as brine shrimp, mysis shrimp, or specialised coral foods 1-2 times per week.
Reef Compatibility: Yes, with adequate spacing. Galaxea spp. can be aggressive towards nearby corals due to sweeper tentacles, so careful placement is essential.
Minimum Tank Size: Not provided, but a mature reef system with stable water chemistry is recommended.
Origin: Not provided.
Maximum Size: Not provided; growth rates vary depending on husbandry and environment.
