I recently bought 2 clownfish from my LFS ,and unfortunately, they passed away after 8 days in my care. One of them had what looked like webbing on its fin, but other than that, I didn't see any physical abnormalities. They began swimming strangely, and seemed to stay at the surface, and within a day, they were dead. Someone on a Facebook site I posted pictures to said it looked like Brook. When I contacted the LFS to ask what I should do to treat it, they told me they doubted it was brook, since they hadn't had a lot of fish dying, and with the shared system their tanks run on, if one tank had Brook, they all would. The only other inhabitants of the QT I had my clownfish in were an arrow crab, which I've had in there for over 3 months, and 2 snails. The LFS suggested that the fish died from chemical burns. It is entirely possible that I might have put my hands in the tank with lotion on or sprayed something near the tank. I have no reason to doubt what they're saying about not having Brook, but it made me think, how do LFSs deal with getting serious diseases or parasites? If you have to run your tanks fallow for 3 months after having Brook or Velvet, I'm sure a LFS can't afford to do that. If things are running on a shared system, it wouldn't just be a matter of changing out one or two tanks. They'd also have to change or disinfect the whole sump system. With the number of people I see on R2R who have had serious diseases, I imagine LFSs must have them on a regular basis. Does anyone know how they deal with these issues?
