Hi I have a huge problem. got a 75 gallon new tank. Cycled it totally great! put in our Red tail shark in from our 20 gallon totally healthy. Still have 6 barbs, pleco, and1bumble bee catfish in the 20 gal. Added 8 tiger barbs and the pictus catfish. all was well in the tank. A couple of days later went back to get 8 green barbs that we had ordered had asked the lady at the LFS where we had gotten the original tigers about a little red mark that a few of our tiger barbs had. She said that "oh that tank that you got them from had a little bacterial infection let me know what is going on." totally good with everything knew what was going on. So 2 days later we noticed one of our tiger barbs had fuzzy stuff growing on his mouth then a little while late another one had a start of fuz. Looked it up and it is cotton mouth. We took the 2 tiger barbs back told them what was going on. Long story short more are showing signs of it I would really like to Not lose the rest of my fish. Any ideas or remedys for this? Have been dosing with melafix and pimafix. HELP!
