I added some new fish to my tank it was a flame angel sailfish tang chocolate tang from my LFS. Since then I developed both infections in my tank. I have been treating it with Pimafix and Metafix with no success. Since then I lost all three above fish mated pair around clowns lawnmower blennies 3 damsels pajama cardinal tomini tang and coral beauty. I have no fish left I've also lost 3 snails due to this. Now what do j do to restart my tank to allow fish. I have several corals 3 anemones a scallop a sand sifting star fish and copapods galore in the tank. I have purchased new fish and waiting to pick them up to add to my tank. Any help is greatly appreciated. My tank is 150 gallon tank. I also gave a copapod breading tank set up separate from main tank
