One of my Rosy Barbs has become very itchy. He should not have any unicellular parasites since he was salted for 14 days in the past. This fish hides in the plants all the time and flashes like crazy. I've taken him out of the main tank and put him into the hospital tank to isolate him. All my other fish are acting normal. Since he was salt treated, I decided to treat with Rid Ich+. He does not seem to be showing stress from the medication. Maybe it could be a form of Costia that is salt resistant (I've heard of costia thriving in 9 teaspoons of salt per gallon). Was this the right course of action. The boards were down so I had some trouble consulting with you guys prior to taking this approach.
