i've always increased the temperature and treated with WS3 or Protozin. small cichla can be a little sensitive to treatments but one drop per gallon should be ok..
Are you refering to ICH or is this something totally different? I got completely rid of mine in two days with temps at 90 degrees along with salt treatment and dosing Quick Cure...
fount out got a nitrite level so done a 50 percent water change to dilute it down and gonna get some live bacteria today to help seed filter quicker but ammonia is zero.
