Yes going fallow... Didn't qt and learned the hard way. Blue hippo tang got ich and wiped out the whole tank. The blue tang was scratching on the rocks so bad it was damaging it's own skin and leaving gashes. Gonna invest in a nice qt and qt all new fish. Starting over as far a fish are concerned. I still have invertebrates and will be adding corals. I will continue to feed the tank so the shrimp, crabs, and corals can stay healthy as well as the beneficial bacteria. Any comments or suggestion are appreciated... just be respectful about it. I have learned my lesson the hard way.
