What should I do

--------------------------------------------------------------------------------

There are two or three white dot on my clownfishes body. I think it is ich. But only have two white dot, Is it necessary to cure them with chemical medicament ? I think they will be fine without treatment, right?
My black ocellaris that caught brook a week ago was infected brook again. I saw there are a little white thing on the body, just a little. Should I make them go to formalin bath? I have adjusted temperature to 30 degree.
If my fish catch brook I can cure them with formalin. But how can I get brook rid in the water that the fish live in? I take the fish back, the fish will be infected again.
I am so sorry for my poor English. But any reply will help me. please help me. Thank you inadvance.

If you give all the fish in the aquarium a formalin bath every other day for a total of three treatments, you will likely rid the display of Brooklynella.

Thank you very very very much.
but if I take the fish that have been cured back, they will be infected again by the old water.

Brooklynella reproduces and spreads fish to fish. It does not drop off of the fish to reproduce like many of the other common diseases of marine fishes. If you effectively kill all of it that is on the fish, the fish should be safe.
