I am pretty new to saltwater.. So please excuse my ignorance if I do not know proper terminology for everything.. But I know my 30g has velvet and may have ich as well. My boyfriend did like many others and didn't qt new fish and one give the tank velvet. We treated the two with velvet and they passed. The entire tank of fish went into a qt tank and was treated for two weeks even though they had no signs of ich or velvet.. After losing 4 fish I suggested maybe the 10 gallon was to small and our only option at the time was placing them back into the main. Well now two clowns and a blenny are showing good signs of velvet/ich.. They are still hosting to their anemones and eating but I have to do something.. My boyfriend is irritated and doesn't want to fool with it anymore. I do.. I read where the inverts should be moved into a seperate tank as well.. So I have two 10 gallons.. I was planning on removing all of the rocks and coral out into a bucket so I can catch the fish.. And placing them in one tank and the anemones in the other tank.. Then placing the rocks and corals back.. In between the swap I plan on doing a FD individually on the three fish showing signs. I am going to set up the 10 gallons with oxygenated same temp fresh saltwater while I run and grab copper.. Is there any other suggestions or anything I am about to do wrong that I need to know.. Please help me. I don't want to lose my fish..
