You don't need the sand for QT. Bare-bottom with some fake plants for hiding (heater and filter) is all that you need.Thanks; as it's been a week, I take it I should go ahead and do this , as it doesn't seem likely that he's going to recover? Seems better to start now while he's eating? Also, I've read that I can set up a 10 gal hospital tank by taking 10 gal of my tank's water, and some of the sand, and a little bit of the biological media, adding a filter and bubbler, and put him in it? I didn't add iodine, I was nervous about taking him out, should I do that now?
