Unless all the other species are SPF (specific pathogen free) and there
are no imports of other species, the risk to your stocks is significant.
The addition or proximity of other aquatic animals always creates the
possibility of a biosecurity failure.
My experience with any new animals in my facility that didn't come
from a trusted / known source has been very poor. I have mixed
species and that isn't the problem, it is the probability of a biosecurity
breach on one species impacting the others. For example, I had to
add some gene stock for breeding guppies that came from Sri Lanka.
These stocks went into quarantine system for 3 months and appeared
free of disease. However, they carried at non detectable levels a strain
of Flexibacter columnaris that my zebra danios had not seen and it
took me several months to clean up my zebra's again.
Many of the aquatic diseases can be transferred by insect vectors,
which will render all but the most biosecure facilities open to transfer
between system in a nearby room. If you can do it, the best aquatic
animal biosecurity is a 10 minute or more walk between facilities
(enough time for hands to dry and far enough to discourage casual
movement and other transmission methods).
For high value animals, biosecurity is a major issue.
