Can' really make the pic out, but it could be mouth fungus, columnaris.

I had this classic sympton when breeding these rainbows back in the early eighties. Add a small amount of Cooking Salt (not table salt) to their aquarium. That will soon clear things up.

thanks how much is a small amount?

If I remember correctly it was about a tablespoon to every 2 gallons. ( I did my waterchanges using 2 gallon buckets).

Be careful adding salt to a freshwater tank. Some fish are very sensitive to, what is after all, a pollutant. If you have scaleless fish in particular, Corys, Loaches etc., do not add salt to your tank, medicate the rainbows in a seperate tank, this is a good idea anyway.

Sorry I forgot to mention the obvious, as I was breeding them in their own tank, and there were no other inhabitants. Please take note of what what Lateral has implied if they are housed with scaleless fish, and reduce the dosage accordingly.
