Table 1 Characteristics of enriched food sources used in feeding experiments of Dentomuricea aff. meteor and Viminella flagellum, including average ± SD of the created C concentrations in the aquaria, total provided C per coral fragment and per coral organic carbon, fractional abundance (F13, F15) and carbon to nitrogen (C/N) ratio. CC: Chaetoceros calcitrans, NG: Nannochloropsis gaditana, BP: Branchionus plicatilis.
