Care
Goniastrea Coral requires moderate to high lighting and moderate water flow to thrive in a reef aquarium. It is important to provide stable water parameters and maintain calcium, alkalinity, and magnesium levels to support its skeletal growth. This coral can be fed with a variety of meaty foods and planktonic supplements to enhance its growth and coloration.
Symbiosis
While Goniastrea Coral does not have any specific symbiotic relationships that are as iconic as those of clownfish and anemones, it does host a variety of microfauna within its structure. These tiny organisms can include beneficial bacteria and small crustaceans, which contribute to the overall health of the reef ecosystem.
Habitat
Goniastrea retiformis is found in the Indo-Pacific region, typically in shallow reef environments. It can be found at depths ranging from the intertidal zone to about 20 meters. This coral prefers areas with moderate to strong water movement, which helps to deliver nutrients and remove waste products.
