Comparing the capacity of five different dietary treatments to optimise growth and nutritional composition in two scleractinian corals.

ABSTRACT: Developing an optimal heterotrophic feeding regime has the potential to improve captive coral growth and health. This study evaluated the efficacy of three exogenous diets: Artemia nauplii (ART), a commercially available coral diet (Reef Roids) (RR), and a novel, micro-bound diet (ATF), against a comparatively natural, unfiltered seawater treatment (RAW), and an unfed, ultra-filtered seawater treatment (CTL), in adult Acropora millepora and Pocillopora acuta nubbins. After 90 days, both species showed significantly positive weight gain in response to one treatment (A. millepora-RAW, P. acuta-ART), and comparatively low growth in response to another (A. millepora-ATF, P. acuta-RR). The results highlighted substantial differences in the nutritional requirements between species. The nutrition
