I just bought a flame wrasse yesterday, and this morning it clearly had ich. I’m debating going fallow and treating all my fish with copper in qt. However I have quite a few fish (one spot foxface, tomini tang, melanarus wrasse, pair of clownfish, starry blenny, benggai cardinal, flame wrasse and a yasha goby). How would I go about setting up a qt tank for all these fish, (tank size, filtration, etc), would it be better to do two tanks? Or should I just wait on going fallow and see if the one fish gets better with good feeding as it settles in? Thanks
