Differentially abundant bacteria in Dascyllus abudafur tissues associated with probiotic-treated in comparison to the placebo-treated Pocillopora verrucosa colonies. Top differentially abundant ASVs identified in the ANCOM-BC2 analysis in A) skin, B) gut, and C) gill tissues. The associated genus taxa are color-coded by phylum. The W test statistic from the ANCOM-BC2 is shown (negative W indicates decreased taxa while positive W indicates enriched taxa in probiotic-treated fish compared to placebo-treated fish individuals). “Unclassified” ASVs are available in Supplementary Tables 4-6.
