you ask What do you mean. Well I learned the hard way about mixing store fish and wild fish. I had a healthy tank for an assortment off goldfish. My daughter while swimming over the summer in our local river caught a couple small trout and sculpin, all alive. After begging for a while I finally agreed to add them to the tank. Well in about two weeks all were lost. But now I am happy to say I now have four tanks up and running with a wider variety of fish.

. Never since quarentining them. Sorry for your loss.
