LFS: how to handle "traded in" fish
I've been thinking lately about what it would take to open a LFS.
To start off, how to handle customer fish?
I think it is a good idea basically to encourage loyalty and to get a source of cheap fish.
But the main problem is that not everyone does a good job with keeping their fish and so customer fish might be carrying diseases, or be inbred, or a variety of problems.
But generally, would it be a good idea for a LFS to set up a bunch of quarantine tanks for customer fish? Observe them for like 7 days before integrating into the general population?
