Inferred direct interactions between microbes. Based on the “sparse and low-rank” (SLR) model, direct interactions between microbial ASVs were inferred by controlling the effects of shared environmental preference. Only the ASVs that appeared in 30 or more samples were targeted in the analysis of each tank. The links between nodes represent potentially positive interactions between ASVs. The color of nodes indicates a partial correlation between ASV abundance and eels’ activity level (controlled variable = pH). ASVs included in minor sub-networks (number of nodes < 5) are not shown
