I am in the hobby 2 years and almost quit in the first year because of problems with ick. Have had no problems in over 1 year since I started to QT and hypo all new fish. I have had some die off of snails and crabs over time and am thinking about buying a new crew. I think I should QT them as well, though obviously not hypo. My question is do others QT new inverts and how long can inverts survive in a glass bottom QT? I'm thinking I should QT about 5 weeks, just like fish. My 20 gal QT has 2 Chromis to keep it cycled and has a few fake decorations, but no live rock. What should I do to help the inverts survive?
