PacBio sequencing results (10 most abundant species identified in each compartment). The top ten species were identified by adding the reads from both replicates and then identifying the ten most abundant. The farms (yellow vs. orange) feature distinct communities, with distinct compartments within farm A sharing more species biofilm samples between farms. For example, Haliscomenobacter hydrossis, a species known to cause bulking, is ubiquitous and unique to farm A. Only three species, Sphaerotilus natans, Streptococcus thermophilus, and Flavobacterium terrigena, featured among the most abundant species in both farms. Aeromonas hydrophila was obtained from a tank in farm B that had an active Aeromonas spp. outbreak. The table further includes gram stain, respiration method, and additional information about the particular species. Updated species names are denoted as footnotes. Green diamonds represent tank biofilm, light blue triangles represent tank water, and dark blue triangles represent biofilter water. Uppercase captions indicate that the phylum was also detected in the other datasets; MS MiSeq, MG Metagenomics
