The LFS operates all community/semi aggressive tanks on the one big tank plumbing system, is that a contagious disease worry on a fish buy?
We don’t have a hospital tank. Should we set one up and routinely quarantine each new fish from the LFS (PetS) with an anti-bacterial med as we used to do with copper on marine fish? If so, what medicine for routine use? We hope this is not necessary, but it goes back to these Molly problems.
