I will answer with another article from AquaBiomics, or better graph from this article. It looks as if Pelagibacteraceae are one of the most abundant bacterial families in established reef tanks, so perhaps we are not trying to replicate nature, but nature still find ways into our tanks.Interesting link.… but that leads to an even broader debate (for another thread). Are we trying to (or should we be trying to) replicate what is in nature in our captive reefs?
