Two of my fish, Falcula Butterfly and Yellow Cowfish have the Ich and need treatment. All my other fish and inverts are fine at the moment. For obvious reasons I cannot treat the main display with copper.....
My question is, can I lower the salinity levels in the main tank safely for 4-6 weeks to control/eradicate the Ich or do I have to qt the two fish and treat with hypo seperately?
If the second option is true, how do I ensure my main display is free from the parasites before re-introducing the two fish? I do have a uv
unit but am not entirely convinced as to its effectiveness due to the two sick fish although none of my other fish are infested (2 firefish, 1 percula, 1 dragon wrasse and two blue damsels).
, invertwise I have two skunk cleaners, a peppermint cleaner, several turbos, three hermits, a long-spined urchin and about 150lbs of lr
