The Petsmart in the Highlands has a dropsy outbreak in a few of their tanks. Mainly their guppies have it, but I don't know how their water system runs in those tanks, and the guppies are mixed with a few different species of fish (including their ADFs).
I kindly pointed it out to one of the employees before leaving, but I don't know if they've done anything as of yet. But I just wanted to give anyone a quick heads up about it....though I don't think it'll make much difference. Petsmart is well avoided
