This small specimen is ideal for marine aquarium enthusiasts looking to enhance their reef display with a coral that offers both aesthetic appeal and moderate care requirements.
Care Level: Intermediate. Galaxea spp. require stable water parameters and moderate attention to lighting and flow.
Lighting: Moderate lighting is recommended, such as LED or T5 fixtures providing approximately 100-150 PAR. Avoid intense direct light to prevent bleaching.
Water Flow: Moderate, indirect water movement is ideal to keep the coral healthy without causing tissue damage.
Placement: Position the coral on a stable rockwork base with adequate space around it to prevent aggression towards neighbouring corals, as Galaxea spp. can extend sweeper tentacles.
Diet: Primarily photosynthetic via symbiotic zooxanthellae, but benefits from occasional feeding of meaty foods like brine shrimp or specialised coral foods.
Reef Compatibility: Yes, with adequate spacing. This coral can be aggressive towards nearby corals, so maintain sufficient distance to avoid stinging.
Origin: Not Provided.
Maximum Size: Not Provided; typically medium-sized colonies in captivity.
Minimum Tank Size: Recommended 75 litres (20 gallons) or larger to maintain stable water conditions.
Regular monitoring of water quality, including calcium, alkalinity, and magnesium, is essential for optimal growth. This coral adds a stunning focal point to reef tanks and is suitable for hobbyists with some experience in LPS coral care.
