My last of 4 fish died today.The 2 clowns and dottyback from ick and my firefish today. He hasn't had the spots for 2 weeks so I thought he was ok. I only have 1 shrimp,a few snails,and a few urchins in the tank now. Am I correct in saying I don't add anything else for 6 weeks and if it was ick then this will kill it? I think I will start 10 gal qt
tank now. Does it have to cycle? Do I do regular water changes in the qt
tank? I read where people set up and take down qt
tanks but how does that stay cycled?
