Native Habitat and Species Information
Fijian Green Acropora native habitat, distribution, behavior & aquarium compatibility.
The Fijian Green Acropora (Acropora humilis) is a compact and slower growing form of Acropora coral that exhibits a brilliant green and purple coloration. Like many species of coral, the Acropora humilis will vary it's coloration between green and bluish/purple depending on the lighting used and the corals proximity to the lighting source.
This species can thrive under various lighting types and intensities, but always does best with strong water flow. Strong water flow should be considered an absolute requirement for the Fijian Green Acropora to thrive and grow within the reef aquarium. Fijian Green Acropora (Acropora humilis) is not recommended for beginning reef aquarium hobbyists and is considered a difficult species for intermediate reefers and a moderately difficult species for advanced hobbyists.
Acropora humilis is categorized as moderate to difficult because of it's requirement for very stable water parameters and very strong turbulent water flow, which require a mature reef aquarium with advanced powerhead / controller systems to achieve.
How to successfully keep Fijian Green Acropora in the home aquarium.
Fijian Green Acropora's are a peaceful species of Acropora coral that are well suited for upper reef placement within well established reef aquariums. They should be placed in an upper area of the reef away from more aggressive species of corals that may sting it with sweeper tentacles. Acropora humilis is a slower growing compact species of Acropora coral which is highly dependent on strong water flow and strong lighting (500 to 600 par) in order to grow and thrive. High placement on the reef in conjunction with lighting suitable for a reef aquarium will allow the Fijian Green Acropora's symbiotic algae zooxanthellae to provide the vast majority of it's nutritional needs.
The trick with this coral is to provide it with very strong turbulent water flow that will allow for the removal of waste products from within the compact structure of the coral. However, this needs to be achieved with water flow that is both very strong and at the same time turbulent, and not just pounding the coral with direct non-stop flow.
Lastly, the Fijian Green Acropora requires that the aquarium exhibit very stable and consistent water parameters that typically require a mature reef aquarium and an advanced reef hobbyist to achieve. The very stable nature of their native environment has made the Fijian Green Acropora intolerant of sudden change; however, aqua-cultured specimens may be more able to deal with aquarium life better than wild collected mother colonies.
Feeding & Nutrition
How to feed and provide proper nutrition for Fijian Green Acropora.
Fijian Green Acropora (Acropora humilis) contains the symbiotic algae zooxanthellae from which it receives the majority of its nutritional requirements through photosynthesis. It generally does not require any supplemental feedings but may pick up micro coral foods or micro-plankton foods designed for other tank invertebrates.
