I am a technician at a zebrafish facility with approximately 5000
fish. Recently, a few of our fish have gotten extremely swollen
abdomens and no longer reproduce. A vet came in and did some tests on
two sick fish. His diagnosis was Aeromonas spp. We were sent some info
on Aeromonas and from what I understand, it is a normal bacteria
living in the fish.

Am I correct in this understanding? Should I be worried or need to
start treating the fish? Or is the vet's diagnosis useless because all
of our fish would test positive for Aeromonas (and maybe he did not
understand this because he is not too familiar with zfish)?

Thanks for any help!
