Hello again, i just took out another dead 9 fish in my tank. Including rainbow, paradise fish, emperor tetras and neon tetras. Thht is 3 days i have been treating with Protozin now. I only have two large plecos, Bull dog Pleco, and a copule others. I have a spare tank do you think i should run keep this running incase of another outbreak then i can put all infected fish in, does this solve the problem or will WS be in the tank at all times. If only one fish is infected with WS and i take it out will this solve the problem?
