beth, in my 1st post i mentioned ich outbreak in main display. i now have a qt tank set up but since setting it up & doing further research i don't think its big enough to qt the rest of my fish. i have 5 1/2" blue green chromis, 1 6-line wrasse about an 1" & 2 damsels also about an 1". my clown seems to be responding to current treatment & showing no signs of any difficulty. my main display is being treated with reef safe ich treatment recommended by lfs it is a 15 day treatment & last treatment will be 2morrow, i am already prepared to repeat cycle when i do another water change which is scheduled for thurs. i know the only success i may have however is to remove all fish ( i wish i found this forum much sooner) to a qt tank to treat there & leave them there long enough to hopefully end life cycle of ich in main display. my qt tank is only 10g.
